PREFACE

TO THE FIRST EDITION.


No product finds so many and ample applications as color. Nearly every
trade requires it for the decoration of its products so as to adapt them
more generally and pleasantly to the present demands.

The art of marbling is that branch of our trade, in which color is
brought into use for the decoration of bindings, yet it has not found
the desirable general introduction into our book-binderies because
practical men have not so intently employed their time and endeavors, to
overcome the difficulties, which resist its general application.

Who could solve easier and more correctly than the mechanics, to whom
these difficulties and obstacles offer themselves in practice? He is the
only one to find the remedy, scientific men not possessing sufficient
technical knowledge. Only he is ready and able to stand up for such
special trades, to work and to fight for them, who is himself interested
and who not only learned to understand the art of marbling from former
instructions and traditions, but from his own practical experience.

To him only, will it be possible to gain by close study true points, on
which to further develop the whole subject.

My original plan was, not only to remove the technical difficulties of
the art of marbling, but also to ascertain the correct colors from the
mass at present manufactured, for the purpose of manufacturing marbling
colors.

But in this I did not succeed as easily as I expected. Every color
manufactory possesses another system to produce its products, and after
thousands of experiments I was finally forced to resort to chemistry for
the purpose of gaining a knowledge of the raw products viz: earths,
metals, acids, bases and their conditions and qualities in order to
study their compositions and precipitations, the coloring composite of
lake colors and their bodies, and to subject them to investigation on
their effects on marbling size.

This was a tiresome work which demanded much patience and pertinacity.
During these investigations, I have learned to know the influence of
sizing upon colors and how it hindered or expedited a beautiful marbling
or comb edging.

Through these experiments I unexpectedly gained a certain knowledge
which enabled me to overcome the technical difficulties of the marbling
art. The greater the difficulties the more they aroused my zeal to
surmount them and the greater my joy when victory was won. During my
investigations I saw, that not the color itself, but its body, to which
the color is bound either in a natural or chemical way, forms the
important part of the colors necessary to our purpose. No branch puts so
many critical demands upon the preparation of colors as the art of
marbling, because, aside from the most careful grating which can only be
done by using the best of painter's colors, there must be a great power
of divisibility and excellent covering qualities so that the pigments do
not turn pale by the propelling power of the ox-gall expanding on the
size, but retain in a dry state, their full lustre. It is therefore
impossible without a more thorough knowledge of the chemistry of colors
to find from the legion of colors, which are thrown upon the market, the
ones best adapted to our art. So much more so as, in most recent times,
by simplification in the manufacture of most colors their quality, for
marbling, has most essentially deteriorated.

Colors which are used for painting, lithography and printing with the
greatest success may be entirely unfit for marbling. The cause is not to
be found in their preparation for our purposes, but in the manufacture
itself, as the qualities, which are indispensable are not known.

The main attention in the manufacture is directed to the finding of
colors free from poison and which will not fade, when exposed to light,
if they are intended for a wholesale consumption in painting and the
graphical art.

All colors which we intend to use for marbling purposes must have body,
because bodiless colors become mixed with the size and run off from the
paper in marbling, they therefore can be designated as useless for our
purpose. The most important composite parts of colors for marbling are
certain substances, among which hydrates of argillaceous earths, tin and
lead oxides and sulphate of barium are named as the best.

A great number of coloring matters of organic origin, which are soluble
in water, have the propensity in mixing with a solution of salts of
lead, tin, and argillaceous earths, with a metallic oxide to form a
compound which is soluble with difficulty (and is termed insoluble,)
when the latter is precipitated from the solution by an alkali. The
precipitations which are obtained in this way are known as lake dyes. Of
greater importance for the quality of the marbling colors are the
physical conditions of these precipitates, they are either crystallized
or amorphous, the former not possessing any value to us.

The serviceable, i. e. the amorphous precipitates, by their quality of
great divisibility give excellent colors.

Among the great number of numeral colors there are many which in spite
of their amorphous properties are bad marbling colors, such as the
compounds of copper, zinc and arsenic. Often it depends upon the manner
of manufacturing, even if the color have a good body whether it can be
used by us, as, for instance, white lead and barium both of which can be
produced as good or useless colors.

The general idea, that light colors are the best, is erroneous, even
heavy oxides of metal being excellent colors. Not in weight but in
divisibility rests the excellence, for instance I mention pure oxide of
iron, cadmium, sulphate of mercury and mercury iodide. These are all
heavy metallic oxides and good colors.

Exclusive of the colors the different ways of sizing are most essential
parts of marbling. They exercise a great influence on the success of
beautiful edges and for that reason I directed my closest attention to
them. The more homogeneous and the smaller the viscosity of the mucilage
of the sizing, the better for comb, peacock and bouquet edging.

Marbled and veined edges demand more viscosity of the mucilage, which,
if the sizing does not possess it, is usually formed during the first
stage of decomposition, when the normal time for using it for comb edges
has passed. I will mention further on the ox-gall and the sprinkling
water, which are indispensable on account of their binding and expanding
powers for the purposes of marbling.

It is an easy manipulation to prepare ox-gall, so that it does not
decompose, but on the other hand a much greater attention must be paid
to the binding and expanding powers of the same, as they may have, in
spite of its excellent qualities for color, by insufficient caution in
their handling the most deleterious influences on the colors as well, as
on the sizing and in most cases are the causes of the failure of the
edging. There are several substances, which possess qualities similar to
ox-gall and many others which possess only its expansibility.

To the former belong resins which are insoluble but which can be
dissolved by the addition of ammonia or borax, to the latter fatty acids
of alkali, which we know by the name of soaps and which I shall describe
in the article on ox-gall.

Sprinkling-water is mostly used on account of its greater expansibility
and its propensity to form circular spots on the marbling ground,
(sizing) for veined edges, or as an addition to the ground color of the
marble edge. Although it does not possess the binding power of ox-gall
for colors in such a degree, it is nevertheless, worthy of our
attention. It was the aim of my investigations during many years to
bring this all into a harmonious ensemble, and produce a fine and paying
work.

In composing this book, I have aimed to arrange it in such a way, that
it will be a guide not only to the uninitiated, but also to the
practical mechanic. For this reason the book will only give such methods
of the marbling as will be crowned with sure success and which have
given me satisfactory results.

As books, which are intended for practical men, can only obtain an
intrinsic value by combination of facts, gained by practical experience,
with scientific principles, I have attempted to attain this object and I
hope to have created a lasting work of our trade-literature.

PREFACE

TO THE SECOND EDITION.


It is a pleasure and a satisfaction to every author to write the preface
to the second edition of his work, as the sale of the first proves
sufficiently, that it has found recognition and commendation.

In the second edition, I have given the results of my uninterrupted
studies and the new observations I have made during the last five years.
It is my hope not only, that I shall make the study easier to the
inexperienced, but also to offer to the experienced marbler a practical
compendium in cases of frequently arising difficulties.

The publisher of this new edition has added to it a number of samples,
which were collected under my supervision and which certainly will be
highly welcome.

I hope and wish that the new edition with its practical arrangement,
with its description of my newest observations and with its tables of
samples and the other additions and improvements, will find the approval
of the trade and will increase the number of friends and patrons of the
marbling art.

    Budapest,
       Very respectfully,
                 JOSEF HALFER.

HISTORICAL.




HISTORICAL.


Every branch of industrial art possesses its champions and originators,
who have employed their whole intellectual and physical powers to solve
problems for the purpose of enhancing and furthering their material
welfare.

Often from small beginnings, within a longer or shorter period of time,
great enterprises spring into existence, which greatly further our
development in culture, science and arts, and are blessings to the whole
civilized world. The material welfare arising from them renders it
necessary that new champions continuously enter the arena and combat in
the cause of progressive industry.

The industries of color and paper making which play most important parts
in the art of marbling shall be the first subjects of my essay.

The paper industry which is very highly developed will have a much
better future on account of its possibilities in the line of
improvement. To-day, in the iron-age, we speak of a paper-age, and for
good reasons, because there hardly passes a year which does not bring
new discoveries, showing the extraordinary adaptability of paper. One
branch of the paper industry which to-day is considered as an especial
part of the industry is the manufacture of colored paper, the origin of
which, as far as our literature is able to state, extends as far back as
the first part of the last century.

From it springs the art of marbling, which in latter years was
introduced into our trade.

The manufacture of colored paper makes a second branch of industry
indispensable and one which stands on as high a stage of development as
the paper industry; this is the manufacture of colors, which deserve the
greatest attention on our part on account of the marbling art.

There is hardly a second branch of chemistry which is of such a great
old age, historically proven, as the color industry.

We hardly know of a nation on the whole globe which does not make use of
color in some way. The use of color for the purpose of embellishment and
adornment dates back to historical times. Nature itself, by the beauty
of the colors of her flowers and minerals acted as a teacher in the
artistic development of the human race.

Egyptian wall paintings show richly developed forms and figures adorned
with multi-colored fabrics.

This is a proof that the Egyptians not only understood the art of the
manufacture of colors but that they also knew the much higher art of
fastening the color on textile fabrics, i. e., the art of dyeing.

In olden times for the coloring of objects, mineral colors which occur
in nature the result of a decomposition of metals and earths and had
only to be put through a sieve and washed to adapt them to the painters
use, were exclusively used.

To alchemy, which was the origin of Chemistry of to-day, we owe a
surprisingly large number of artificial mineral colors, for the reason
that with predilection it brought metals, earths and mineral compounds
within the sphere of its researches which were aimed at the production
of gold, but which all were ineffective in this direction. But the time
and labor, which were employed in these investigations, were not thrown
away. By alchemy an immense number of chemical compounds became known,
without which knowledge the chemistry of to-day would not have reached
its exalted stage of perfection.

Exclusive of mineral colors several organic colors came into use, the
most being applied in the dyeing establishments as they were bodiless
colors and at that time the art of binding them to metallic oxides was
unknown.

By and by it became known in what way to bind the coloring matter of
plants to bodies and to make them serviceable in the art of painting and
the graphic arts. Since that time progress in this field has been so
rapid that we gaze in astonishment upon the achievements of the color
chemistry of to-day.

The progress which developed industrial art and caused it to flourish,
was enhanced by a new and highly important invention, the industry of
tar colors.

It is wonderful how man through the vigor of his intellect, tears from
nature her hidden treasures which have lain in obscurity for thousands
and thousands of years.

Who would have thought, that the antediluvian vegetation with its
splendor of thousands of colors should celebrate its resurrection in
aniline colors which by their splendid qualities of richness and
intensity over-shadowed everything before them? It is a pity that we are
only able to use these colors in limited numbers in our trade.

Up to this time they are used more for dyeing purposes, because they are
without body and possess two apparently insurmountable proclivities,
1st, they do not mix so intimately with oxides of metal as the organic
coloring stuffs of plants and they cannot for a long period withstand
the influence of light.

In the meantime it is to be hoped with confidence, that science will
soon find the solution for these difficulties. Already the forerunners
of body colors have been discovered, a few which could withstand light
have followed, as geranium lake in which the coloring matter is only
bound to oxide of lead by surface adhesion. Furthermore scarlet lake,
which, although bound to oxide of lead, has been put in such a state
that it does not run and lastly the artificial krapp-(madder) lake and
indigo, which have been produced from coal-tar and nearly equal to the
good color lakes of the animal and floral kingdoms.

The main attention in the production of these colors is directed to the
end of finding those which are free of poison and will not fade, to make
them serviceable to the historic art of painting.

For the aniline color there is therefore a wide field open to
experiment.

Whether our interests and demands in regard to colors will be fulfilled
is a question of time.

Even the newer productions of the animal and vegetable kingdom already
differ in quality from those indispensable to the art of marbling.

I recommend to my honored colleagues to read my book with attention, so
that the intended gain shall not be missed and the beautiful art of
marbling may attain a larger circle of friends.

                            THE AUTHOR.




THE SIZE.




THE SIZE.


The first process in marbling is the preparation of THE SIZE on which
the colors are to be floated.

By the name of size is meant a consistent glutinous mass, which is
obtained by boiling or dissolving with water certain bodies derived from
the vegetable kingdom.

Mucilage is found in many plants, especially in the outer skin of seeds,
also in many roots, barks, stems and leaves, but its solubility and
consistency are very much varied.

Generally the mucilage of plants is classed among the gums; but there is
a large difference from them in this, that it will not give a perfect,
diaphanous and homogeneous solution, but only swells in it to a thick,
massy and viscous fluid, which is similar to starch paste. It is
composed of small quantities of gum, starch, sugar and consistent
plant-mucilage. If prepared from certain plants, for example the algae
of the sea, it also contains small quantities of iodine.

Starch swells in hot water, while with mucilage the same result is
achieved by using cold water.

Smaller quantities of mucilage are found in every plant, but larger in
gum tragacanth, carrageen or Iceland moss, salep, the leaves of
mallows, or of colts foot or tussilage, the roots of marsh mallow,
seeds of plantago-psyllium, (flea-bane) linseed and quinces.

Of this number but few are of interest to us, which I shall mention
further on.

The density and proper consistency of the size depends on the bodies,
from which the viscous or glutinous substance is derived and also from
the quantity of water, in which it is dissolved. The consistency of the
size is also materially influenced by the temperature, the warmer, the
less substantial and the more pliable; the colder, the more consistent
and stiff it is.

A good marbling size should be an entirely homogeneous mucilage, i. e.,
a solution, which should be free of any vestiges of seeds or strings
undissolved. A less viscous size is more adapted to the production of
comb-edges, while a more viscous size to the production of marbled or
veined edges. The consistency of the mucilage of every kind of size will
soon experience an essential change, which becomes apparent by the fact,
that the size becomes less consistent, until finally an acid reacting
fluid remains, which has no more value for marbling purposes.

This chemical process is produced by the transformation of the sugar
parts of the dissolved starch contained in the size into acid and
lactic-acid. The more starch and sugar that is contained in the size,
the sooner the acid will be generated, while pure plant mucilage
containing but little sugar and starch will resist much longer
disintegration.

All plant-mucilages, which are soluble in cold water, i. e., swell, will
keep much longer than those dissolved in boiling water, because the
soluble parts remain inclosed in one cell which is only broken by the
boiling heat or by the formation of acid. This is the reason why they
only swell up in cold solution.

A homogeneous mucilage will serve for marbling much better, than that,
which is produced by swelling, because the latter has an injurious
influence on the fine distribution of color for veined, comb and other
edges. Although the surface of such a size seems to be smooth, the eye
will discover on closer investigation the undissolved bodies in the
small granules of the size.

The mucilages obtained by swelling are always milky-cloudy and never
permit the colors distributed upon them to expand with the same purity
and smoothness as the homogeneous varieties, on account of the small
granules hindering the drawing of the colors on their surface. On the
other hand there are varieties of size, which are very viscous on
account of a too homogeneous mucilage and therefore from their nature
are not adaptable to any kinds of edging which must be drawn by the
stylus. The colors can simply not be drawn on the surface, because this
very viscous mucilage is drawn along by the stylus instead of being cut
by it.

In investigating the different varieties of size I have noticed a very
surprising action of the extremely viscous mucilage, which nearly
confused me for the moment. I have scalded with boiling water
plantago-psyllium (flea-bane) and have beaten it with wicker-rods tied
together so as to produce in a better manner, the mucilage found on the
outside of the seed. After cooling it off, I filtered it through a linen
cloth and poured it into the trough but have not waited till the very
viscous thread of mucilage parted after the trough was filled to a
certain height, but have placed the vessel on the floor and to my utter
surprise the thread of the size spread out and reached the vessel on the
floor, becoming gradually thicker until finally the whole size flowed in
a white stream with great velocity over the rim of the trough (2 inches
high) and returned to the vessel standing on the floor until the trough
emptied. This was done in a very short time. The cause of my surprise
was in the very consistent mucilage which took along ever-increasing
quantities of the size and finally entirely emptied the trough.

Prepared colors, which on a less viscous size are normally distributed
expand with a greater velocity to a greater extent on a more viscous
size and therefore become pale.

For such kinds of sizes the earth colors are preferable but only for
marbled edges.

The normal strength of size can be discerned without araometer or other
recommended apparatus. My opinion is that 2/5 of an ounce of good
carrageen moss to a quart of water are sufficient, as carrageen excels
all other glutinous bodies by the quantity of mucilage contained in it.
To test the correct strength of the size pour some of it into a flat
vessel, as a plate or dish, and throw a drop of color upon it; if the
color does not spread out, but rather sinks down a drop of ox-gall must
be added. Renew the test and so on until the color spreads out to about
2 inches, then take the stylus and draw the color into lines as in
producing comb-edges. If the size be too thick the color will be drawn
along by the stylus and cannot be cut clean through. On the other hand
if the size be too thin it can be seen immediately in its quivering and
the running of the color, which cannot be drawn into straight lines. In
the former case some clean water must be added to the size, in the
latter case which, if the size be well boiled, seldom occurs, thick size
must be added by boiling more. The real consistency of the size is so
easily learned in practice that a mere feeling with the fingers will be
sufficient.

The preparation of the colors is carried on separately on a small part
of the size, so that the whole quantity is not rendered useless. If the
colors are rightly prepared in proportion to their expansibilities in
relation to each other, the new size is to be poured into the trough and
the marbling may begin.

The mistake which is commonly made in marbling is, that too little
attention is paid to the size and color. Frequently the size is soiled
and the colors are spoiled by adding too much gall before an edge is
produced. For this there are generally three causes, either the size is
too fresh, too thick or the colors have been prepared on the same size
by which the edges are to be produced.

Each size which is boiled should only be taken into use after perfect
cooling and after several hours have elapsed, since in a warm state it
would not permit the colors to expand even by adding a large quantity of
gall. Only after the expiration of ten or twelve hours after boiling
will it have the correct quantity of mucilage and then only the size
possesses its full value. This time having elapsed, the size is filtered
through a cloth and is then ready for use.

A size when too thick, allows the colors to expand only with great
difficulty and demands a three fold larger quantity of gall than when it
possesses its normal consistency. It is very difficult to remove from a
too consistent size the remnants of colors.

They always unite with the size and in this way the size not only
becomes soiled but it is impregnated with a large quantity of gall. As I
said before, the colors should always be prepared on a separate size
which can be poured into a flat vessel as it is nearly impossible to
prevent several drops of color sinking to the bottom.

If this precaution be taken and if the colors are prepared according to
their relative expansibilities as they are used in the order prescribed,
the process will not meet with any obstruction or difficulty. As the
size plays such an important part in marbling, great attention must be
paid to its preparation if it is desired to make a good base for the
colors. I especially recommend to laymen that they direct their
attention to the consistency of the size, as this is always the key to
the production of good edges.

The different peculiarities of the varieties of sizes, viz; evaporation,
influence of temperature, starry formation of colors, formation of
angular scales in comb-edges, and all other things which have influence
on colors, will be treated of in a special article on the varieties of
size.




CARRAGEEN MOSS.




CARRAGEEN MOSS.


The Carrageen or Iceland moss, or lichen is one of the algae of the sea.
Chondrus Crispus grows on the cliffs of the Atlantic Ocean and the North
Sea. Carrageen smells slightly of iodine and when uncleaned tastes
offensively salty. Like all seaweeds it contains a great quantity of
mucilage and small quantities of salts of iodine and bromine. When
washed in sweetened water it becomes nearly tasteless and is without
smell. On account of the great quantity of mucilage contained in it, and
of its action as an alleviative to pulmonary complaints it has found
many applications in medicinal practice and is given to the patient
boiled in water, milk or bouillon or as gelatine in cases of coughs and
diarrhoea, being a slightly nutritious substance.

The carrageen moss or Iceland moss or weed is a lichen and consists of a
tuft of flat deeply divided cartilaginous fronds of an olive brown,
sometimes yellowish or reddish white color; the tuft is sometimes 2 to 5
inches long.

The moss is used in many ways; as size for marbling edges, for
clarifying beer, as linen-weavers starch, for finishing cloth and in the
production of iodine.

The good pure carrageen is horn-like, yellowish-white, contains a great
quantity of mucilage and gives the best size for marbling, as it
complies with all the requirements of a good size. It is homogeneous, of
great consistency, not extraordinarily viscous and cheaper than all the
other materials containing mucilage which are used for marbling, but is
inferior to gum tragacanth as far as durability is concerned, and that
it must be subjected to boiling, but this trouble is amply repaid by the
beauty of the productions.

On this size all varieties of edges can be produced, and by its
diaphanous watery mucilage it gives an excellent ground to work upon.

The preparation of carrageen size is confined to one ever recurring
manipulation, which must be repeated every eight days, if an always good
and useful size is desired; the expenses are very trifling, a few cents
for the best kind of carrageen. If bought in larger quantities the
expenses for carrageen can still be reduced. For the preparation of the
size take a new pot, which must always be used for this purpose
exclusively, pour in six quarts of water, which quantity is sufficient
to twice or three times fill the usual marbling trough, add 2-1/2 ounces
of Carrageen moss and boil until the water bubbles up several times. A
longer boiling is injurious because the mucilage becomes flaky and
muddy. 2/5 of an ounce of Carrageen to one quart of water is fully
sufficient to produce a consistent size, provided that only the best
Carrageen is used.

Soft water or rain water was formerly used exclusively for preparing the
size, as by using it a greater durability was obtained.

During my researches, regarding the durability of the varieties of
sizes, I found means by which the influence of hard water on the ground
can be suspended, so that spring and pump water can now be used without
any danger.

Every kind of hard water contains mineral salts, spring water especially
containing lime in smaller or larger quantities. This can be seen, when
the soap, which is used in such water, curdles, because of the
ingredients of soap stearine palmitic or fatty acids of sodium or
potassium, form a combination with the lime, to carbonate of lime, and
the potash soap is converted into an insoluble lime soap. If we add to
hard water a quantity of sodium or potassium, the carbonate of lime is
precipitated as a white or yellowish powder, according to the quantity
of iron contained in the water, and a soft water remains.

The sun produces on a great scale in nature, what the chemist achieves
on a smaller scale by evaporation or precipitation and cooling of steam,
a water free of all mineral salts, which we call distilled water. Rain
water is the same, but the flowing water derived from a river already
contains mineral salts in greater or smaller quantities, which are
brought into it by different springs and substances. The water gained by
precipitations is considered soft. Carbonates of sodium or potassium are
strong bases, exactly the opposite of acids, and they therefore prohibit
the oxidation in plant mucilages. This chemical reaction against the
formation of acids I used for the purpose of prohibiting a deterioration
of the size by adding sodium, in which I was thoroughly successful, as
it can easily be preserved in a cool place for even eight or ten days.

Two obstacles offered themselves, which I have overcome after a tireless
and thorough investigation, first the strongly alkaline property of the
size which was generated by the added carbonate of sodium and second the
fermentation of lactic acid which occurred notwithstanding the sodium
and made the size useless.

The presence of alkalies was injurious to such colors, chemically bound
to bodies, among which red is most affected. The coloring matter was
removed from the bodies and became mixed by running with the size,
causing the size to become soiled. Even the shade of the color was
changed to another which was nearer to purple, and in this way, the
beauty of the color was greatly lessened. The second obstacle is the
fermentation of lactic acids which always occurs where starch flour is
in the solution, causing in consistent sizes a gradual thinning out and
even a destruction of the size.

It was not my aim to save the size from destruction forever, as this is
impossible (laws of nature cannot be obliterated at will) but to keep it
useful for a certain period of time, and this I achieved after many
experiments by using borax.

Borax is a neutral salt of strongly antiseptic properties, prohibiting
fermentation and decomposition where neither base nor acid predominate.
Borax is produced by neutralization of boracic acid with carbonate of
sodium and can be bought at every drug-store.

This salt is sold in crystals of the size of walnuts; for our purpose it
is ground to powder and is kept for use in a closed vessel. The size is
first used without any addition of borax as it is then better adapted
for producing comb and other drawn edges, and only after some time has
elapsed, in summer 36, in winter 48 hours, are 150 grains of borax added
to the size, whereupon the size, having been repeatedly stirred to
dissolve the salt, will keep entirely good and useful for a period of
eight days without doing any harm to the colors. On a size which
contains borax, the colors expand in a much greater degree than upon
unadulterated size, without impairing the consistency of the mucilage.
An unadulterated size is therefore, better for marbled and veined edges,
but if it be desired to produce only marbled and veined edges on the
size, it is advisable to add borax to the water before boiling the
carrageen moss.

As the influence of temperature is important in marbling, and the
production of beautiful edges is often jeopardized by it, it should
therefore have the most careful attention. Every glutinous mass
acquires, according to the difference of the temperature of the size and
air, in one-half to one-quarter of a minute, a film (top) which forms
through natural evaporation.

On a size which has such a film, or top, the colors do not spread out in
such circular forms as on a size on which the colors are quickly thrown
right after the film (top) has been taken off, but form star-like veined
spots which are torn by the film in all directions.

Even in the normal expansion of the drops of color, it often happens,
that the rim of the drop is jagged, the cause being that the size
already possessed a thin top, which was not yet sufficient to prevent
the expanding of the colors. If the size be left standing for a
half-hour or an hour before throwing on the color without having at
first removed the top of the size, the drop will tear a hole into this
film and will sink, even if quite a large quantity of gall had been
added. This explains the contraction and the sinking down of colors on a
still warm size, inasmuch as the top is formed by evaporation of the
warm mucilage, so quickly and so thick, that the color which had already
begun to spread out is pressed together by it and is forced to sink.

The greater the difference of temperature between the size and air, the
quicker is the top formed. It is therefore a rule, that the size should
be allowed to cool off in the same room, in which the marbling occurs,
because in this way a symmetrical degree of heat or cold of the size and
air will be gained. On such a size, the formation of the top is much
slower and thinner, so that even after one to one and a half minutes
after removal of the top of the size, the colors can be thrown on
without the occurrence of the starry formation.

I will here mention a fact to show the importance of temperature. As
this point has given me much trouble and has taken much time and labor,
it was my aim to find that mysterious effect which I was unable to
overcome despite my numerous chemical experiments, until my eyes became
opened and I saw accidentally that this obstacle was the difference of
temperature of size and air. From that time on I was able to prosecute
my labors without the slightest difficulty.

To show the excellence of my marbling colors, I used a great number of
samples, perhaps several thousand, and in order to produce them I worked
on Sunday so that I could employ my whole time to the good purpose. It
was winter; on every Saturday I ordered two pots of size to be boiled,
and to cool them off I placed them in a room, in which there was no
heat. On Sunday morning I filtered the size through a loose linen cloth;
it was as clear as crystal, it possessed the necessary consistency, and
I was much pleased with the results, which I had expected to achieve.

I commenced the preparation of the colors in a separate flat vessel,
using but little size, so as to keep the rest from being soiled, but I
was greatly astonished, when the colors in spite of the addition of
gall, which of course was carefully done by drops, first spread out and
then again were contracted, the starry formation of the colors took
place, whenever I was not quick enough after the taking off of the top
to throw on the colors.

I was dumbfounded and could give no explanation for it; the size was
sufficiently cooled off, it had been standing the proper length of time,
the mucilage was excellent but in spite of all that, these difficulties
occurred.

Thinking that I might be more successful, if I should do the marbling in
the trough where there is more surface offered to the color to spread
out, I filled the trough with size of a sufficient height and then
commenced the marbling, but immediately after the first trial I
instantly recognized that even here my experiments would have the same
result. Although I threw on the color with great alacrity, right after
the top had been taken off, the first drop spread out normally 4 inches,
the second but three, the third two, and the fifth and sixth only one
inch. In this way I received instead of an equally wide band of thrown
on color, one which tapered to a point. If I had not worked according
to the system which I shall describe in the chapter of throwing on of
colors, I would have received already with the fourth drop, a star-like
formation.

Whatever I did to avoid this obstacle was worthless, it was and remained
a mystery and I was unable on that day to produce anything beautiful or
worthy of consideration. This happened several times until, by accident,
and through careful study I found the cause which was nothing but the
fact, that the size was much colder than the air in the room in which I
worked. The evaporation on the surface of the size was so great, that
the top was formed nearly as quick as on warm size and therefore a
favorable result was impossible.

Another abnormity which arises from cold temperature acting on the size
is the fig-like formation occurring during the drawing of the colors.
The cold in some way seasons the surface; this surface becomes mixed in
filtering with the liquid part of the size in numberless small particles
which although the size is well stirred up in the trough by the fingers,
are not dissolved and this hinders the drawing of the colors.

They adhere to the stylus and follow it and arrange themselves between
the color lines in a way similar to a green fig, having a broad upper
and a pointed lower end. Such an edge traversed by the comb will give an
ugly result. A difference of temperature of the size and the air can
also occur when the working room is suddenly heated, or, when in summer
time, the size is kept in a cold cellar. To effectively obviate this
difficulty it is necessary to bring the temperatures of the air and size
carefully to the same height which is made easy by leaving the size,
after boiling, in the room, where the marbling is executed.

In winter, when the room is heated, the size should be poured into the
trough one hour before using, in summer the thing regulates itself
because it is then unnecessary to keep the size in a cool place, the
addition of borax being a sufficient protection against spoiling. But in
spite of it all, in winter-time when in drawing the colors the fig-like
formation should occur, it is advisable to return the size to the pot
and to warm it up slightly so that the seasoned particles are dissolved,
until an equal temperature is reached, whereupon after the lapse of one
hour the marbling can again be proceeded with.

Should the size be too thick the trouble can be remedied by the addition
of some warm water.

The quantity of mucilage contained in carrageen moss varies greatly, and
the consistency of the size often depends upon the quality of the moss.
The quantity which I gave as essential to the preparation of the size
means first class moss.

Should the consistency of the size be insufficient after the first trial
then from 1/2 to 1 ounce of moss should be added as it is clear that
the carrageen moss is not of prime quality. Before I speak of another
variety of size, I will repeat the main condition which should meet with
the attention of every layman and which are as follows; the size must
not boil too long, in order that it may not become flaky and muddy, it
should remain for cooling in the same room in which the marbling is
carried on, so that the temperature of of it and the air are the same;
the colors should be prepared separately on a small quantity of size so
that the whole size cannot become soiled and, lastly, the top of the
size should be taken off before the colors are thrown on, so that no
film can form before the colors cover the surface of the size.

The quicker the manipulation of marbling is executed the prettier are
the edges produced. As soon as the size is covered with color, the
formation of the film is prevented.

As the size is one of the most important parts in the process of
marbling, I recommend these main points to the special consideration of
the reader.




GUM TRAGACANTH.




GUM TRAGACANTH.


Gum tragacanth, also called gum-dragon, is the product of various
species of astragalus which is found in Greece and Turkey and is a
natural exudation of shrubs and from exudations resulting from incisions
made in the stem near the root. This shrub is from 28 to 35 inches high
and two inches in diameter. It is collected in July and August after the
exudations have ceased. It is a hard, tough substance more or less white
according to its purity in very irregular flattened shapes and in
tortuous vermicular filaments. It contains aside from a little gum and
starch, a consistent plant-mucilage without smell or taste and it is
used in technical ways, in printing of textile fabrics and finishing, in
producing plastic masses, as a binding medium for the production of
confections and in the book-bindery for marbling size.

The leaf tragacanth of Smyrna is the best. It is brought to the markets
of the world via Constantinople or via Smyrna in boxes of 100 to 200
lbs.

It forms flat ribbon-like pieces which consist of peculiar layers of
horn-like consistency, white and diaphanous; when broken it is dull and
splintered.

An inferior quality is the tragacanth of Morea, which generally comes
from Greece via Trieste. This consists of oddly shaped, peculiarly
twisted pieces, partly of pure white, partly of yellowish and brownish
colors. For a long while, tragacanth was known as a good material for
marbling size and, for that reason, it is used to-day in a good many of
our book-binderies for this purpose.

It is much more liked than carrageen moss because the consistency of its
mucilage and its durability are great and the preparation of the colors
does not demand such great attention. But since my experiments and
investigations upon the excellent effects of borax on the durability of
carrageen size have become known, tragacanth has lost much of its
popularity, because with it the edges can never be produced in a similar
fine way as with carrageen size and besides the price is higher.
Tragacanth is one of these short-viscous plant mucilages which swell in
cold water but do not give a perfectly homogeneous solution. The
mucilage consists of innumerable small granules, in which the starch is
enclosed by cells.

These small granules prohibit, within the first two or three days of a
fresh tragacanth size, the drawing of edges, as they make the colors
thrown on appear rugged, and in drawing injure the fine hair lines. Five
or six days after the dissolving of the tragacanth, the mucilage becomes
more homogeneous and therefore better adapted for marbling.

If the swelled up mucilage is boiled, after the first or second day,
then the solution will become perfectly homogeneous and will be as good
as carrageen size except that the colors, which normally spread out on
carrageen size, will expand much more on tragacanth size as it possesses
more consistency and therefore they will become paler. The more dense
the size, the thicker colors and the less gall is necessary to produce a
normal expansion. The same difference in the power of expansion of the
colors as in carrageen and the tragacanth is noticed in colors which
normally spread out on tragacanth but which, very largely, expand on the
size of plantago-psyllium (flea-bane) because the latter has the most
consistency and homogeneity of them all. The different effects of the
varieties of size on the colors are due to the consistency and to the
different conditions of gravity. The objections of the consumers of my
marbling colors who use tragacanth, are, that they consider the edges
too pale. The cause of this is that my products are only prepared for
carrageen size, inasmuch as my investigations have shown that it is the
best, the cheapest and the most adapted for all varieties of edges.

The homogeneousness of the tragacanth mucilage in cold solution comes
naturally after the size is five or six days old, because within this
time fermentation of lactic acid occurs, which opens the cells of the
small granules of starch while at the same time boiling heat has an
immediate result in the same direction.

As soon as these cells are opened the formation of acids of the sugary
parts and the fermentation of lactic acid of the starch contained in the
size take place as fast as in any other variety of size, hence the size
of tragacanth has no superiority over any other, besides the best, or
picked-leaf tragacanth of Smyrna costs about four times the price of the
best Carrageen.

For the preparation of the size, take 3 ounces of tragacanth, pour two
quarts of water over it, leave it stand for 24 hours, then stir well and
leave it standing for 12 hours more, repeat this until the homogeneous
thick mucilage has been produced, then add 4 quarts of water, again stir
it up well and filter it and the size is ready for the marbling process.

For tragacanth size, colors of great consistency, mostly fine earth
colors are the best. They must be ground exceedingly well and very
little ox-gall is to be added. But as these earth colors lack in the
power to spread out and in divisibility, a characteristic of colors
prepared for carrageen size, and as they never will have such fineness
and smoothness, always appearing rugged, it is impossible for me to
recommend gum tragacanth for the preparation of size.

I must mention further an effect, which earth colors exert on tragacanth
size, viz., that they can be used on paper not prepared with alum,
without running, while this is not the case with colors, which were
prepared for the Carrageen size. In another chapter upon ox-gall I shall
explain why the colors used with Carrageen size must be transferred on
alum paper.




Salep, Plantago-Psyllium.




SALEP, PLANTAGO-PSYLLIUM (Flea-bane) AND THE OTHER GELATINOUS BODIES.


Radix salep are called the dried tubers of several species of orchids,
they are round, quite flat, yellowish white, horn-like, semi-diaphanous,
very hard and without taste or smell. Formerly salep was imported mostly
from Persia, but now the tubers of orchids grown at home are collected
and do not in any way differ from those coming from Asia. They contain a
good quantity of gum and on that account are used for finishing silks
and for medicinal purposes. It is sold ground, or as powder and can be
bought at every drug-store. As marbling size, salep possesses very
excellent properties, similar to carrageen moss, but its high price
prohibits its general application. In preparing size, use, to 6 quarts
of water 2-1/2 ounces of powdered salep which must be well boiled for a
long period so that it may become entirely dissolved. After standing 24
hours, it can be used in the same way, as carrageen size.

Plantago-Psyllium (Flea-bane, Flohsamen, Flohkrautsamen) is the seed of
different species of Way Bread belonging to the family of the
plantaginea viz., plantago-psyllium, Pl-Arenaria, Pl-Cynops, the second
of which is found in Eastern Germany, Switzerland, Hungary, etc. on
sandy fields, the other two on the sea-shores of southern Europe.

The seed is small with one side flat and the other concave and has a
furrow upon which is located the eye or navel. It is lustrous and of a
reddish brown color, the best varieties coming from southern France. In
consequence of the great quantity of plant-mucilage or gum, that it
contains, by treating with hot water a consistent mucilage or size is
obtained and used in the manufacture of marbled paper and for finishing
textile fabrics.

To prepare the size, place 4 ounces of flea-bane in a wide wooden tub,
pour 6 quarts of boiling water over it and beat well with a switch of
wicker-rods until the gum is entirely separated from the seeds, allow it
to cool and after 10 or 12 hours filter through a linen cloth, when it
is ready for use. The mucilage of flea-bane is quite homogeneous and of
great consistency, is very viscous, forming strings very readily and is
therefore not used for drawn edges since the colors will be drawn along
by the stylus without being cut. It is mostly used for producing thickly
veined, ordinary marbled edges, but flea-bane size is also much more
expensive than that of carrageen moss and on the other hand its quality
is so much inferior to that of the other that I cannot recommend it for
use as size.

I will briefly mention the other vegetable matters containing an
especially large quantity of gum or mucilage, but which have not come
into use for preparing marbling size on account of their cost and of the
less consistency of their mucilages.

The richest in this regard are the seeds of quinces and linseed. Their
mucilage is as viscous as that of flea-bane. Much less gum is contained
in the leaves of mallows of colts-foot or of marsh-mallows.

In closing this chapter upon the mucilages of plants and their
applications as sizing for marbling I again recommend carrageen moss as
the best size, because it has given me during my investigations and in
practice, surprising results of its usefulness for all kinds of marbled
edges.




OX-GALL.




OX-GALL.


THE CHEMICAL CONSTITUENTS OF OX-GALL.

In the bile of every animal are two peculiar acids both containing
nitrogen. One of them free of sulphur, the other containing it, both by
boiling with acids and alkalis yield the same acid free of nitrogen,
which is called cholic acid.

If these two acids be separated from each other in a chemical way we
obtain glycocholic acid, an acid free of sulphur and the other
taurocholic acid containing sulphur. The alkali salts contained in bile
are quite soluble in water or alcohol but insoluble in ether. To produce
it in a pure state mix the bile with as much animal coal, (spodium) so
that finally, on evaporation in the water-bath a dry powder results,
from which is drawn, by the use of absolute alcohol, the now colorless
cholic acid esters, cholesterine, choline, lactic acid, etc. When ether
containing a little water is added, the cholic acid esters are
precipitated as colorless plaster-like masses and crystallize, when left
in the fluid for some time.

The so-called crystallized bile is the final material for the
preparation of acids. The acids of ox-gall have been investigated in the
most thorough manner.

Glycocholic acid is obtained as a colorless precipitate from a watery
solution of crystallized ox-gall, by adding dilute sulphuric acid until
the fluid becomes flocculent, which after a while, especially, if the
water contains a little ether, is changed into a voluminous 'magma' of
fine white needles.

If collected upon a filter, these needles unite and form a lustrous
felt.

Glycocholic acid is sparingly soluble in water but soluble in alcohol.
It forms the principal constituent of bile, it reacts feebly with acid
and tastes bitter-sweet. Taurocholic acid is found only in small
quantities in ox-gall and has no important effect on the colors.


THE EFFECT OF OX-GALL UPON COLORS.

By chemical analysis we have seen that glycocholic acid is the principal
constituent of ox-gall and in combination with taurocholic acid, glycin,
choline and lactic acid is soluble in water. On the other hand, when
pure, it is soluble with difficulty and therefore is only of use to us
when in combination with other acids, as it must combine intimately with
water-colors.

The atomic weight of gall and the insolubility of pure glycocholic acid
in water are the most valuable properties of it for the marbling colors.

The first gives to the colors the expanding power, the latter the
adhesion to paper.

All the lower fatty acids, among which ox-gall may be numbered, possess
properties similar to fatty bodies, namely a less atomic weight than
water. They differ from fatty bodies in this, that they mix with water.

The expanding power and lightness of ox-gall are, consequently,
peculiarities of equal value. Marbling size forms the base for the
colors, which by the consistency of the glutinous mass and by the gall
added to them are prevented from sinking to the bottom. They float like
drops of oil upon the water and only differ from them by the fact that
the colors will spread out on the size, while the drops of oil on the
water are contracted to circular spots of small size. If a drop of oil
were thrown upon the size it would spread out very quickly.

This purely physical occurrence is caused by the different weights of
the bodies and the consistency of the size. The fatty bodies, which are
much lighter than water, float upon it but the gravity of the drop
itself prohibits its spreading out, as it sinks somewhat and is held
together by it. It is different with the size; by the consistency of the
glutinous mass the gravity of the drop is antagonized and as a result it
flattens and spreads out.

As I have already mentioned the insolubility of glycocholic acid binds
the color to the paper. To explain this I will mention a few examples;
the saturated alum solution will cause glycocholic acid to curdle. If,
therefore, we add to ox-gall which is basic the saturated solution of
alum, a soft plaster-like mass is precipitated which consists of
glycocholate of aluminium, insoluble in water. This chemical reaction
explains the durability of the colors. If we desire to marble books or
papers we impregnate them with alum water, allow them to dry partly and
take the edge from the size.

In the same moment that the paper soaked with alum comes in contact with
the colors, the latter become bound by the formation of glycocholates of
aluminium and do not run. They have the same property of fixing colors
that resinous soaps used in the paper manufacture for gluing machine
paper have. If this resinous soap were not too strongly basic, which is
injurious to many colors, it might be applied as a surrogate for
ox-gall.

As the resinous soap on account of its binding quality and insolubility
could also be used in marbling with such colors, upon which it exercises
no injurious effect, I will here give its preparation and former use in
the manufacture of paper. If 2-5 ounces of rosin be boiled with 1-1/3
ounces of sodium lye and if you add by teaspoonful from time to time so
much lye until a sample of it is dissolved by hot water to a clear
fluid, the mass on cooling congeals and forms a quite solid soap. If we
mix a solution of resinous soap with one of alum then we obtain an
insoluble compound of resinous acids and aluminium. In this way
resinous soap is used in gluing paper by adding to the paper pulp, first
resinous soap and then a solution of alum. During this process a thin
layer of insoluble soap of aluminium is formed around every particle of
the paper and thus the running of the ink is prohibited. The same
process occurs with ox-gall contained in the colors, when the edge is
lifted off on paper or book-edges impregnated with alum, by which the
running of the colors is prohibited.


THE PREPARATION OF OX-GALL AND ITS USES.

The preparation of ox-gall to be used in marbling is simple. Take a
quart of fresh bile (ox-gall or fish-gall), place in a bottle which
contains when filled from 1-1/2 to 2 quarts, add 1/2 pint of absolute
alcohol, shake well and leave stand for from 14 days to 3 weeks. Within
this time all particles of gum and all fatty substances which are
present in some galls in comparatively large quantities, will fall to
the bottom and the gall will be thin-fluid, pure and diaphanous,
brownish, yellow or greenish according to the nourishment of the animal
from which it was taken.

Cow-gall contains more gum and fatty substances, than ox-gall;
fish-gall, on the other hand, is thinner than ox-gall and would be the
most useful of them all, if it could be obtained in sufficient
quantities. If the gall is thin and pure it is filtered through paper
which is easily and quickly done as it runs like water. If by filtering
the dregs of the gall the filter should become clogged, a new one must
be used.

The addition of alcohol causes the precipitation of glutinous and fatty
substances and preserves the gall from decomposition. If prepared in
such a way it can be preserved for years without spoiling.

All colors which we intend to use for marbling must be bound to bodies
absolutely insoluble in water; it is therefore a mistake to say, that
the colors dissolve in water. You may grind the color on a marble slab
or in a machine as long as you please, but you will only obtain a great
degree of fineness of the bodies but never a dissolution of the same.

Each body possesses its limit of divisibility; in amorphous bodies the
high divisibility is but natural, but in crystalline bodies this
division must be produced by grinding or washing.

The gall does not combine with these bodies, nor does it penetrate them,
but only clings to them loosely. It can be readily removed in case the
colors should be rendered useless by the addition of too much gall. The
color is allowed to precipitate in the bottle and the water standing
above is poured off, fresh water is added and this manipulation is
repeated several times.

The gall which surrounds every particle of color forms, as it were, the
support of it and adapts it to float upon the size.

Bodiless colors, which give a complete solution with water will run
into each other on being thrown on the size and will flow from the paper
when it is lifted off. The insolubility of the color bodies therefore
prevents them from running although they are disarranged on the size in
drawing and although one color may be compressed or expanded by a
second, yet they all remain separate without mixing, except, perhaps,
that the shade of the first color becomes more intense, because its
color particles are pushed together by the more violent expansion of the
second color.

From this it will be seen that the colors, to be useful for our
purposes, must be thoroughly insoluble. The gall is added during the
process of grinding the color, so that the particles of colors are fully
surrounded by the gall. The gall has an excellent effect on the colors
but it also can act very injuriously if the necessary precautions are
not taken. Carelessness is mostly the reason that the edges do not
possess the demanded lustre of color and why they appear pale, as the
marbler often uses the gall too soon when he notices the smallest
obstacle, (due in most cases to the size.) It is therefore not
astonishing that brilliant comb or peacock-edges are so rarely seen.

It is an obstacle to marbling, that the gall mixes so easily with the
size. It often happens that the gall spoils the size before an edge was
ever produced on it. This happens especially when the size on which the
colors are prepared according to the old method, is too thick. The size
is frequently soiled and spoiled when the colors are prepared, because
the colors can not be perfectly drawn off on thick size. There will
always remain some particles which will not only soil the size but
impregnate it with gall, and which will cause the entire uselessness of
size and color.

A very consistent size will make the preparation of colors extremely
difficult, as they need a double quantity of gall for the purpose of
spreading out. If there is but one color used, the preparation on such a
size would be possible without spoiling it, but with four colors this is
entirely impossible because the repeated drawing off of the colors,
which always leaves particles behind, will, by and by, impregnate the
size so that when the fourth color is prepared the first will not spread
out any further.

The more the impregnation of the gall and size increases, the power of
expansion of the colors decreases and this continues until both
materials are useless.

It is therefore advisable, as I have already stated, in the chapter upon
the varieties of sizes that the colors should be prepared separately on
a small part of size to determine the correct consistency of the latter
and to prohibit the whole size being soiled.

The gall should be kept in a small bottle containing about 1/10 quart
with a perforated stopper from which a small tube protrudes and from
which the gall can be added to the colors in drops.

Although the preparation of the color in this way takes more time, this
trouble is amply repaid by the result.

Fatty bodies are injurious to the size, therefore they must be carefully
avoided because they have the same effect as the gall, they form,
although not insoluble in water, a combination with the size and
prohibit the colors from spreading out. Fatty bodies can be transferred
by glutinous fluids into a state of the most minute division and they
then form emulsions.

Natural emulsions are milk, the yolk of egg, and the milky saps of
plants. For this reason, in many establishments raw milk is used as a
propelling medium for hair-veined edges.

There are also fatty bodies which, in an artificial way, form an
emulsion even with water; for instance, almond, poppy and hemp, if they
are ground to a pulp with a little water yield a milky mixture. All
these emulsions artificial as well as natural, can be employed as
expanding mediums and give better results for marbling than petroleum or
naptha.




Substances Acting Similarly to Gall.




SUBSTANCES ACTING SIMILARLY TO GALL.


There are rosins which are soluble in ammonia or borax. These solutions
possess properties similar to gall and either can be used as an
expanding medium or as an addition to colors. Different experiments with
these solutions gave very good results.

To produce them pour a quart of water into a vessel, warm, add 2/5 of an
ounce of shellac or rosin and a 1/100 part of a quart of ammonia or 2/5
of an ounce of borax so that the rosin becomes dissolved, and then bring
the mixture to a boiling temperature.

Ammonia dissolves the rosins much more quickly and thoroughly than
borax, but the solution in ammonia has the property of gelatinizing the
colors after they have remained standing a short time. They therefore
can only be used in a greatly diluted condition. The borax solution, on
the other hand, has no such effect; not even the concentrated solution.
I mention these two solutions especially, to instigate further
investigations.




SPRINKLING WATER.




SPRINKLING WATER.


Sprinkling water is one of the newer discoveries in the art of marbling
and deserves full consideration on account of its good properties. Its
advantages consist in this, that it produces circular forms upon the
size and has a greater expanding power than gall.

Sprinkling water is used for hair-veined edges and as an addition to the
ground color in marbling.

To prepare it take 1-1/2 ounces of Venetian soap, finely chipped, place
them in a pot with a quart of alcohol, warm up some water in a second
and large vessel in which the pot containing the alcohol and soap is
put, bring the whole to boiling, when the soap will be entirely
dissolved in the alcohol. Keep a quintuple quantity of water in
readiness into which the solution of soap is poured and stir well, the
sprinkling water is then ready for use. The solution of soap in alcohol
is carried out in a water-bath to avoid the ignition of the volatile
vapors which are generated by this process. The alcohol prevents the
foaming of the soap, the soft water the curdling.

The solution when ready is to be kept in a closed bottle.

Generally to the colors which are used for hair-veined edges and marble
more gall is added than to those used for drawn edges. It is, therefore,
easily understood that with these, a more intensively acting expanding
medium must be used to spread out the strong colors into veins.

The sprinkling water is here of great service, because, although ox-gall
in its pure state possesses a sufficient expanding power it is here more
desirable to produce beauty of forms. In this respect the gall is much
inferior to sprinkling water, the former producing all kinds of forms,
the latter only beautifully round and oval ones.

For marbling, the ground color is prepared with gall so far, until it
slightly pushes the other colors aside and then, by and by, so much
sprinkling water is added until the desired expanding power is reached.

Every ground color which is prepared with sprinkling water spoils on
standing two or three days becoming slimy and viscous, and, for
economy's sake, not more color should be prepared with sprinkling water
than is required for one marbling process.

For hair-veined edges, the sprinkling water is used in the same way as
gall. Use a large painter's brush or whisk and move the colors by
beating into veins, with this brush or whisk through a slot, or throw
the sprinkling-water upon the color by means of the sprinkling brush and
sieve. In both cases the same result will be achieved.




ALUM WATER.




ALUM WATER.


In the chapter upon gall I have mentioned in a general way the action of
alum water upon the edges, it remains only therefore to explain the
preparation and application of the same.

To achieve beautiful results from the colors it is indispensable to wet
the book edges or the paper, to be marbled, with concentrated alum
water, so that no spot is left free from moisture, because at that spot
the color would not take.

Concentrated alum water is prepared in the following way; put 2 quarts
of water and 13 ounces of alum into a pot and heat until the alum is
entirely dissolved. This concentrated solution is permitted to cool and
is bottled tightly.

A solution of alum in cold water is much too weak for the above purpose
as alum is but sparingly soluble in cold water.

The book edge or paper, which is to be marbled, is wet with a sponge
dipped into this cold concentrated alum solution and must be allowed to
dry for from 5 to 8 minutes, after which the produced edge may be lifted
from the size. Generally this point finds but too little consideration
in our book-binding establishments.

Edges which have not been treated with this alum water show as a
consequence poor and blotted results, although such little trouble is
necessary to wet the edges with alum water.

With hair-veined edges, where colors are thrown on the size only in very
small quantities, this wetting may be omitted; but with comb, peacock
and bouquet edges, for which four to six colors are used, it is
unavoidably necessary to prepare the edges with alum water because the
glycocholate aluminium formed by the color while in connection with the
alum water is essential to fix the color in such quantities.

Therefore, if it is desired to produce clean and lustrous edges in which
the white lines appear without a trace of color, then this advice is to
be followed, the small trouble being amply repaid by the beauty of the
edges.

Ordinary earth and several of the lake-colors take without wetting of
edges with alum water, but these colors leave much to be desired in
their divisibility and fineness and always appear rugged.

A much finer fixing medium is the acetate of aluminium which can be
easily produced.

Dissolve 1 pound of alum in 3 quarts of warm water, prepare another
solution with the same quantity of soda, mix these two, whereupon the
hydrate of aluminium is precipitated. Allow the latter to settle, pour
the water above carefully off, and filter; the white body which remains
consists of hydrate of aluminium which is readily dissolved by a little
acetic acid, into a clear fluid and can be diluted with the same volume
of water. Then heat the whole liquid, when the excess of acetic acid is
evaporated, we have the desired acetate of aluminium which can be used
in the same way as alum water.

Edges and paper which are to be marbled should only be moistened with
alum water or aluminium acetate shortly before the marbling and should
stand not longer than a half-hour after the sizing of the edges, because
later on, an insoluble layer is formed which only takes color with great
difficulty. It is therefore best to prepare the colors before commencing
the sizing of the edges. If there are a large number of books, it is
better to divide them into two or three lots.




The Preparation of the Colors for Marbling.




THE PREPARATION OF THE COLORS FOR MARBLING.


The want of knowledge of colors gave me the greatest trouble when I
began their manufacture as I had no information as to why this or that
color was unfit for marbling.

The numberless experiments I made to this end remained without results.
It was an exceedingly great trial to my patience, but by the pertinacity
with which I clung to my investigations, I, at last, succeeded in making
the important discovery, that the real value of color for marbling
purposes is its body and that the color itself, which is bound to the
body either naturally or chemically, is of less importance. By this
discovery every difficulty that I had so long experienced was cleared
away and it was made manifest, why it had been impossible for the
marbling art to become sufficiently popular.

From this time on I had a foundation, upon which to continue my
investigations with greater surety. Finally I succeeded in finding that
the colors named later on are good and useful marbling colors.

When we look over the different special branches of our trade, we find
everywhere great progress, which is even noticeable in the smallest
workshop. Already, these wonderful achievements have become common
property, only the art of marbling stood still on account of
insufficient instruction and it has not made any progress in the last
decade. This was due to a large number of men in our trade using
mechanical marblers to avoid those obstacles, which had hitherto offered
themselves in marbling.

The expectations which were placed on the mechanical marblers were not
fulfilled, because, after a short use, and when not carefully kept
clean, they became sticky from dust and color mixing so that they gave
but very indifferent productions. The necessity of continually cleaning
these mechanical marblers and their lack of uniformity are by no means
recommendable properties.

Mechanical marblers should be retired to small book-binderies for use
upon single books, where they are eminently in the right place, driving
away the primitive sprinkled or starched edges.

The interest which was shown in mechanical marblers is a proof that all
members of our trade, who use them, possess a liking for the marbling
art and would be zealous friends of the same, if they but knew of the
methods of marbling, that would give beautiful results without great
difficulty.

To judge rightly the value of a new invention, we have only to see,
whether it is introduced into the wholesale trade and is in continual
use. This is the best test of inventions and the only proper basis,
upon which to judge them correctly. We find the mechanical marblers
exclusively in the small shop, because they do not answer the demands of
the wholesale manufacturer in any way.

What the marbling art is able to offer, a person can only judge, who has
seen exemplary edges and to whom marbling is not a stranger. No kind of
edge, to which color is applied, can be compared to the effective
splendor of marbled edges. In thousands of variations it imitates nature
and delights the eye by its products. Although marbling has hardly
reached the middle rung of the ladder of its development, it to-day
stands unrivalled.

It is clear, that such an art should be fostered and nursed, if it is to
grow to its full development. But here the investigation of one man is
insufficient, a general interest is demanded and I hope, that this will
be aroused by my work. After this slight diversion I will now begin to
treat my real subject, the preparation of colors, and for that purpose,
I will divide the marbling art into three important parts: the size, the
color and the technical application.

The size and the technical application of the colors demand great
attention and practice; on the other hand, the preparation of colors but
labor. The colors are divided into two groups, mineral and lake colors.
In the lake colors, if they are good and strong, the coloring matter
bound to the metallic oxides is equal to one-half of the whole weight of
the color, therefore they can be prepared as good marbling colors
without adding anything but gall. On the other hand, in mineral colors,
which in a natural or chemical way are bound to bodies, the body weighs
much more than the coloring substance and even if the metallic oxide is
the real coloring substance, as is the case with ferric hydrate, the
organic coloring matters derived from the vegetable or animal kingdom
are preferable to the inorganic substances.

Why this is the case we shall see further on. In those coloring
substances, which I have recommended as good marbling colors, the
aggregate state of the body is amorphous and admits of the greatest
divisibility. If such a coloring substance is ground in the finest way
possible, the division of the body is a very great one, but an intimate
union of the particles can never take place because first, the color is
insoluble in water and, second, because the division (diminution) of a
body has its limits. For this reason particles are isolated and lay
loosely alongside of each other.

If a mineral color is mixed with the necessary amount of water and gall
and thrown upon the size the drop expands to a round disc, which upon
close investigation, is found to consist of numberless small dots. When
such coloring stuffs are used, the union of the particles must be
brought about by some glutinous matter. This is unnecessary with lake
colors, where the coloring matter is as heavy as the body to which it is
bound, as all organic substances possess a sufficient quantity of
glutinous matter to form a union of the particles.

The clearest proof of the correctness of my allegations we find in a
mineral color, in which the metallic oxide was precipitated by a semi
organic salt, I mean French blue, which without any substance unites the
particles quite well if the washing of the precipitate after the
blueing, was a perfect one.

The glutinous matter used with mineral colors must be entirely free of
any acids as the smallest particle of acid, which in warm weather is
often formed after long standing causes an isolation of the coloring
matter in such a way, that it will become curdled when thrown upon the
size. The best glutinous matter, that can be used, is dissolved
isinglass or parchment-glue with gum tragacanth. As the first two named
materials are expensive they can be replaced by fine gum arabic free of
acid. Take 4/6 of an ounce of gum tragacanth let it swell in 1 pint of
water and dissolve fully by boiling. In this way we obtain a glutinous
mass, which is mixed by stirring with a thick solution of gum-arabic.
This mixture is used to unite the particles of the body of mineral
colors.

To grind the colors use a very smooth marble slab, a roller and a
palette knife, of wood or horn, as those of steel produce some change
upon red colors.

The colors which are sold in the market are either in the form of
grooved pieces, little cones, or powder. If the color is in pieces or
little cones, it is first ground to powder in a dry state and is then
mixed with a little water and from 10 to 15 drops of ox-gall to a thick
paste. If a mineral color, add a piece of the glutinous matter the size
of a nut, if, on the contrary, we have a lake color, the addition of
water and gall is fully sufficient.

Now commences the grinding. With a muller you continually run in a
circular motion over the color using a moderate pressure of the hands.
After about two or three hours have elapsed the color will have the
requisite fineness which is shown by its greasy, lacquer-lustrous
appearance. During the grinding, move the color from time to time into
the center of the marble with the palette knife and at the same time the
adhering color is removed from the roller.

When the color is ground fine it must be diluted with water in a glass
vessel and is then ready for use. Bottle tightly and keep it in a cool
place, best in the cellar.

For grinding the colors and diluting the same, river or rain water
should be used, of course, proportionately to the quantity of color so
that the latter will not become too thin.

The grinding of a color is done mostly by apprentices as the time of a
journeyman would be too valuable. In most cases this part of the
preparation gives the greatest trouble, since the colors are seldom
gotten to that fineness necessary to marbling. This is easily explained
as the grinding demands practice and a certain perseverance. From the
point of view that time is money, the majority of book-binders concluded
to use ready ground colors and this was profitable to them as they could
buy them better and finer ground and much cheaper. But, even here, we
sometimes find articles, which leave much to be desired, but which, in
most cases, can be used.

For fifteen years I have been carrying on the manufacture of marbling
colors and must always endeavor to keep pace with the progress of the
chemistry of the colors as new products are continually offered for sale
superior to the old in quality and beauty.

To give to the trade an idea of the manufacture of marbling colors I
will briefly describe it.

It is a well known fact that among the great number of colors produced
by a factory, there are always several, which excel by their especially
good quality. I selected, therefore, from among the colors of several
factories, those which were especially excellent and I now control an
assortment, which hardly any single factory is able to supply.

In preparing them 20 pounds are always ground at once. The color is
ground upon a large marble slab with water and gall, to mineral colors
the necessary glutinous matter is added and this is formed to a thick
paste and then ground in the color-mill. The grinding in the mill is
essential to obtain a homogeneous mass and then this paste is ground
twice on a color grinding machine with three porphyry rollers in the
finest possible way.

The color having been diluted is then prepared on a size, which is
gotten up for this purpose and then preserved in stone jugs.

It is easily explainable, that the best results must be obtained with
such a carefully and excellently prepared color, I, therefore recommend
to my fellow marblers, the marbling colors manufactured by me.[A]

 [A] The publisher of this book, having accepted the sole agency
  for the United States and Canada of these colors, pledges the closest
  and most prompt attention to all orders, despatch in delivery and most
  reasonable prices.

  See price list at the end of this book.

Before using, the color must always be well shaken and there must only
be taken from the bottle enough necessary to one marbling process. The
remaining portion of the color must not be poured back into the bottle,
because if this be repeated several times the whole color would be
spoiled by the gall.

A small quantity of, say from 40 to 50 drops of color, is sufficient for
marbling the edges of even a large number of books, the colors must
always be kept tightly bottled up as they may be spoiled by being
exposed to the air for a longer period.




The Marbling of Book Edges and Paper.




THE MARBLING OF BOOK EDGES AND PAPER.


The Marbling consists, generally speaking in this, that finely ground
fluid colors are thrown in drops by the aid of brushes on a thickly
fluid size contained in a flat trough, that then by the aid of gall,
different marble-like designs are formed, that they are lifted off the
size by immersing the edge of the book and by that are transferred on
this edge.

Before speaking of the different kinds of edges, I will mention
something of the harmony of colors, as in drawn edges the real
harmonious combination of colors is of great influence on their beauty.
The application of color in the art of marbling gives us certainly
extraordinary freedom and a wide range to our fancy, but nevertheless
there are certain principles or laws necessary to make the colors appear
in an effective and beautiful way. Those tones of color which lie
between yellow and reddish yellow are called warm, those between blue
and the middle of reddish blue, cold colors. In the center lies red by
its strength and effectiveness forming the dividing line between the
warm and cold.

To explain the principles of color harmony, the colors are divided into
three groups, first, primary colors, second, secondary, and third,
tertiary.

Primary colors are those which cannot obtain their inherent purity by
any mixture, namely red, yellow, blue, white and black. Secondary are
those which are generated by a combination of two primary colors, for
instance, orange, purple, green and grey. Tertiary, or broken colors,
are those which are obtained by mixing two equally powerful secondary
colors, for instance, brownish red, olive, slate grey, etc.

In the harmony of colors luminosity and intensity play the main parts.
The darkest color must occupy three times as much space as the lightest
and the succession must be kept up in this way always taking into
consideration the luminosity of the colors.

Which colors must now be placed alongside one another to produce a
harmonious effect? The laws for this are founded on the peculiarity of
the power of man's vision. The eye, demands to be satisfied, an accord
of primary colors. Red requires to annihilate one sided irritation the
two primary colors, yellow and blue. The secondary green is obtained by
a combination of yellow and blue, for that reason green is the color
demanded by red to please the eye. But there must be a contrast of
colors, for instance light red and dark green or dark red and light
green must be brought together. The same thing is the case with other
primary colors. The primary color yellow demands the secondary purple,
blue, the secondary orange, the tertiary color olive, the secondary
orange, brownish red and green, brimstone yellow and violet.

The correct treatment of the shadow tone of a given color depends upon
the knowledge of the laws of the annihilation of color effect. As in
nature, a shadow is formed by obstructing the light, so in the technic
of coloring the shadow is obtained by the annihilation of the
light-color. By combination of a primary color with a harmonizing
secondary color of equal strength, we obtain the right shadow tone of
the first color. In this way, by experiments in mixing, the right shadow
tones, which form in a multi-colored edge, the gradual transitions of
primary colors can be easily detected.




THE COMB MARBLE.




THE COMB MARBLE.

(SEE SPECIMEN PLATES.)


The comb or nonpareil marble belongs to those edges which are not so
frequently used, although it is superior in brightness and variety of
colors to other marbles, provided the combination of colors is a correct
one and there are no entire blotches of the same color present. For the
comb-marble in general use, four colors are mostly employed, namely
black, blue, yellow and red. To these white is added, but not as a
color, as it is formed by the stylus in drawing the colors.

For precaution's sake let me here repeat the description of the
preparation of colors: before using them shake well and then pour into
the different small vessels as much of the same as is necessary for one
marbling operation only, then put them away handy for use in the
following order, black, blue, yellow and red. Black is used for shading
all other colors, therefore, it should be thrown on first as the ground
color. As I mentioned before, the colors are to be prepared upon a small
surface of size so that the whole size may not be soiled, as it is
nearly unavoidable during the preparation to prevent several drops from
sinking. Whether the colors are suitable to each other as regards their
expanding power or whether the size is too thick or too thin for
comb-marble is determined in the following manner; draw off the size in
a dish, by a strip of paper, throw on a drop of black, which if size and
color are correctly proportioned must expand to a spot of 4 inches in
diameter. If the drop does not expand in this way the size is either too
thick or more gall must be added to the color. Add from 5 to 10 drops of
gall to the black color and repeat the experiment. If then the color
does not expand to the given diameter take a stylus and draw it in wavy
lines such as used for comb-marble. If the color can be drawn into
beautiful straight lines, without following the stylus, the size
possesses the normal consistency and more gall must be added to the
color, until it reaches the aforementioned diameter, but if the color is
drawn along by the stylus or cannot be easily cut by it, then the size
is too thick and must be carefully diluted with water. If, on the other
hand, the color in drawing with the stylus should run, then the size is
too thin. This can also be easily seen by the extraordinary quivering of
the size. Such a size cannot be used for comb-marble, either you must
add some thick size or you must use it for common marble edges. The
black color is the key to the success of a beautiful edge; the other
colors must be prepared according to the strength of the black.

When the ground color has spread out to the desired dimension, throw on
the black a drop of blue, then yellow on the blue and red on the yellow
which must all expand to a diameter of 1-1/2 inches. Should this not be
the case then several drops of gall are to be added in the order
aforesaid. The three latter colors must be prepared by themselves, and
if, after throwing a drop of blue on the black, the former does not
reach the necessary expansion, gall must be added in drops until this is
achieved, then the yellow is manipulated in the same way.

When all colors are toned in regard to their power of expansion, then
and not before then, can the marbling commence.

With a little experience or practice the whole manipulation is finished
in less time than it takes to describe it.

Pour the size into the trough, take the top of it off with a thin piece
of wood which fits into the trough closely, smooth it over with the wood
so that the surface is free of bubbles, then throw on, by the aid of a
hair brush, the black in the direction of the length of the trough
towards the centre of the size in such a way that the first drop comes
in contact with the rim of the second, the second with that of the
third, the third with the fourth, etc., so that a ribbon from 4 to 5
inches wide is formed. Then throw on the blue in drops at both sides of
the black following the length of the trough, but the joining of the
drops must be avoided. Yellow is thrown on at both rims of the black
just as the blue was but in such a way that each drop of blue has a
yellow centre. Finally red is thrown on the yellow so that each drop of
yellow receives a red centre. By this means we produce a beautiful
combination of colors. Then take a thick knitting needle or a thin
stylus of wood and draw the colors in wavy lines through each other but
so that the stylus will pass the boundary of the black. By doing this
white lines will be produced between the colors, adding at the same
time, the fifth color white which causes the marble to attain a brighter
aspect. If then the comb is drawn across, beautiful scales will be
produced.

The books which have been wetted shortly before with alum water, are now
placed between boards or clamps and are dipped from right to left,
somewhat obliquely, into the trough so that the left end of the book
touches the size first, and then with a firm hand the book is inserted
towards the right until the right end has touched the size. This must be
quickly done to avoid the formation of air bubbles. As soon as the
marble edge is taken off, the superfluous size is carefully removed from
the edge by a moist, soft sponge so as to prohibit moisture from
penetrating too much into the leaves of the book. In this operation
great care must be exercised to prevent the marble edge being rubbed out
or spoiled.

The remainder of the color is to be taken off the size by the aid of
strips of paper and this is done in the following way: one strip is
inserted into the size at the left end of the trough in such a way that
it slightly enters the size, then by the aid of a second strip of paper,
the top of the color is taken off beginning at the right end of the
trough and moving the film to the left till it is brought between the
two strips of paper and can be removed from the trough into a basin
which is kept ready, to receive the waste color. If the colors are
quickly removed in this way, the size itself remains perfectly clean
even though a large number of books be treated.

On good work, the book at first is only cut in front. As soon as the
front edge is marbled and dry the book is backed, and cut at the top and
bottom; both edges are wetted with alum water and again the colors are
thrown upon the size taking care, that the scales of the upper edge run
in the same direction towards the fore-edge as those of the lower one.
In more common bindings, all three sides are cut together and after the
front edge is marbled and the book is rounded and backed, the marbling
of the upper and lower edges is executed without delay.

The rounding of the book must be done before the marbling of the upper
and lower edges, because the comb would become disarranged, if the
rounding were executed afterwards. Remember that always before throwing
on the colors, the top of the size must be taken off by the aid of the
piece of board, as, by evaporation, a film is formed over the surface
which does not permit the expanding of the colors. The quicker the
marbling is executed, so much more beautiful will be the edges.




PEACOCK MARBLE.




PEACOCK MARBLE.

(SEE SPECIMEN PLATES.)


Peacock marble is one of the newest and prettiest of marbles. It has
been much used in recent times for end papers of books, which receive
the same edges and in this connection gives a beautiful effect. The
method of preparation is generally the same as that of the comb-edge,
the difference being this, that, after the colors have been drawn by the
stylus into wavy lines, it is drawn by the aid of a movable comb, (the
preparation of which I shall describe among the tools) in such a way,
that for a distance of 1/2 inch the comb is made wider and again after a
distance of 1/2 inch is made narrower. This is continued until the
entire marble is crossed by this opening and closing comb; of which a
trial is all that is necessary to make it all clear.




THE BOUQUET MARBLE.




THE BOUQUET MARBLE.

(SEE SPECIMEN PLATES.)


There is no doubt that from among the drawn marbles the bouquet marble
is one of the most brilliant, as it can be compared to a number of
buttonieres placed alongside each other, if the combination of colors is
a good one.

In the manufacture of colored paper, the bouquet marble is mostly
produced from two or three browns and one black, and is often used for
lining end papers in fine books.

After the colors have been thrown on, drawn by the stylus and combed in
the ordinary way, a rake-like wooden instrument is moved through the
colors right and left across the whole surface of the size so that in
moving the rake the teeth of the second row trace those of the first row
precisely, and so on until the rake has been moved over the whole
surface from the right end of the trough to the left. A somewhat changed
design is produced by treatment of the colors in the same way leaving
out the marbling comb and spreading the drops of color thrown on only by
the aid of the stylus into very narrow cross-lines and then using the
aforementioned rake as already explained. The rake consists of a piece
of board of hard wood, of about 1 inch less in length, than the width of
the trough, 1-1/4 inches wide and 1/2 inch thick, into which are
inserted two rows of sharply pointed wooden teeth about 1 inch distant
from each other and leaving a space of about 1 inch between the two
rows, in such a way that the teeth of the second row are situated
precisely between the teeth of the first row.




ENTWINED COMB MARBLE.




THE ENTWINED COMB MARBLE.

(SEE SPECIMEN PLATES.)


This comb-marble, produced by drawing the comb back, is a great favorite
on account of its beautiful designs, but is more adapted for thicker
books as on those only can the pattern be seen to full advantage.

The production is entirely the same as that of comb marbles, but the
teeth of the comb must be about 1/2 inch distant from each other and the
comb must be 1/2 inch less in width than the trough so that it can be
moved right and left at will, when the marble is drawn by this comb the
latter is drawn back in such a way that the teeth cross the centre of
the scales.




THE SNAIL MARBLE.




THE SNAIL MARBLE.

(SEE SPECIMEN PLATES.)


The production of this marble is very simple. The colors are thrown on
as for comb-marble and are drawn by the stylus into wavy lines and then,
one by one, by the aid of the stylus, snail forms are produced.


THE GRAY SNAIL MARBLE.

The manner of production is the same as that of the plain gray marble,
with the exception that so much green is added till a desired tone is
obtained. After this ground-color has been thrown on, the marble is
drawn by the aid of the stylus into snails and then taken off.


THE COMMON GREENISH-GRAY SNAIL MARBLE.

To produce this the colors are thrown on in the following order, black,
light-blue (two parts water, one part Oriental blue,) Indian yellow,
pink, light red, gall water, and, finally, the body color, composed of
one part black and two to three parts sprinkling water according as the
demand is for a lighter or darker body color. Throw the colors on the
same as in producing the grey marble, (see marbled edges) and when the
ground color is thrown on draw the marble into snails and take off.


THE DARK BLUE SNAIL MARBLE.

To all the dark marbles, which should have an especially brilliant
effect, and are adapted for light-colored bindings, there is always
added one or two parts of a solution of shellac and ammonia to the body
color, in addition to sprinkling water. To produce this marble take
black, light brown, light blue, (one part Indigo, two parts white,)
lemon yellow, gall water and the body-color, which consists of two parts
Indigo, one part black, from one to two parts sprinkling water and the
same quantity of shellac-ammonia solution. After everything is thrown on
the snails are formed.


THE DARK-RED SNAIL-MARBLE.

This marble has a beautiful effect and is especially adapted for fine
half bindings with light-colored leather backs and corners and end
papers of the same pattern as the edges. To produce this the colors are
thrown on in the following order, black, light red, pink, light gray,
(four parts white, one part black,) gall water and the body color
consisting of two parts of carmine lake, one part of black and two parts
of sprinkling water and shellac-ammonia solution. After throwing on the
ground color the snails are drawn.


THE GRAYISH-GREEN SNAIL-MARBLE.

To produce it the colors are thrown on in the following order, black,
claret red (two parts carmine lake and one part of black well mixed,)
pink (ten parts of white and one part of scarlet red) gall-water which
forms the white veins, and, finally, the body color, which consists of
one part of black, three parts of sprinkling-water and an addition of
green according to what shade of green is desired.




GENERAL REMARKS UPON DRAWN MARBLES.




GENERAL REMARKS UPON DRAWN MARBLES.


All marbles that are drawn by the stylus or knitting-needle are, in
their treatment, more or less similar to the comb-marble, therefore the
way to produce them is similar to that described in the former article
upon comb-marbles.

To produce a pretty coloring, it is unavoidable, to use those four
colors which I have named in the former article on comb-marble.

If it is desired, to use more colors than the four named, greater
perfection in marbling is essential and it takes a perfect practical
marbler to achieve beautiful products with eight colors, but practice
and a zealous heart will even overcome these difficulties. The lustre of
the colors is due to their combination, according to their power of
spreading out and to their harmony.

Wall-paper will frequently show what beautiful and fine effects can be
produced by three, or at the most four colors.

If the colors are separated by white, they develop a greater lustre,
while black employed in the same way is productive of a more sombre
effect.

The separation of colors by white and black is most decidedly more
profitable and effective, than a marble in which the different
variegated colors immediately touch each other. It is therefore
advisable always to take black as the ground-color, white will be
produced without adding any coloring matter whatever by the drawing of
the colors with the stylus.

Black is the ground-color, upon which all the rest, blue, yellow, red
are thrown; it is understood, that they must expand in the proper
proportion, to produce a clear marble.

The lustre of the colors is mainly a result of white and black, which
form, as it were, a frame about the other colors by their own
durability.

The other colors, which we may add to the four nonpareil colors, are,
different shades of red and yellow. A bottle is filled to one half its
height with carmine-lake, then black is added until a very deep purple
is obtained; another color is a powerful orange, which, if not on hand,
can be produced by mixing red and yellow. To produce a beautiful
combination use the following colors, black, light blue, orange, light
yellow, purple and finally scarlet red, (a color which I have recently
introduced under the name of safflower carmine) this combination of
colors gives a surprisingly beautiful result. To produce the nonpareil
(or comb) marble with eight colors, two more mixed colors are used, one
of which serves as a shade to light blue, while the other enhances the
lustre of the lighter colors. To this end, pour a little dark-blue into
a glass bottle and mix it with the same quantity of green, obtaining a
dark bluish-green. As a second color mix green and white until the color
is pale green. To produce a desirable effect with these eight colors we
must observe the following order, black, light blue, dark bluish-green,
orange, light yellow, purple, pale green and scarlet-red.

In this wise numberless variations and combinations can be obtained, but
it should always be taken care, that the primary colors only receive
shading tones of secondary or tertiary colors. The mode of throwing the
colors on the size is always the same as I described it for nonpareil
marbles namely; form a ribbon of black from 4 to 5 inches in width in
the prescribed way and throw the other colors into the black and at both
rims of it but so that they are situated within the black. The same
colors which are on one rim must also be thrown upon the other rim in
the most uniform way possible. The marble therefore, before it is drawn
is similar to a ribbon which has in its centre the black stripe about 2
inches wide, and on each side, a border of different colors 1 to 1-1/4
inches wide.

The more colors are used for the drawn marble, the less of each color
except black should be thrown on the size. Although the colors have been
adapted to each other in regard to their power of expansion before using
them, it is indispensable in producing these marbles with such a large
number of colors to assist the expansion of one color or the other by a
few drops of ox-gall.

It is necessary to see, that the second color should not too greatly be
displaced by the third, the third by the fourth, etc., because the
color, which is mostly displaced would not appear in the marble at all.

In producing peacock marbles, I obtained most excellent results even
without primary colors. They were not so bright and lustrous in their
general color effect, but their most subdued tones were most pleasing to
the eye.

To one of these marbles I used the colors in the following order; black,
medium olive green, dark bluish-green, bronze or ochre yellow, dark blue
and bright chrome yellow, (to obtain the olive, use the following
mixture; 3 parts light orange, 1/2 part dark blue; bluish-green as
described above; ochre yellow, 2 parts light chrome yellow, 1 part
brown; blackish-blue, 2 parts dark-blue, 1 part black; light chrome
yellow, 2 parts light orange, 2 parts white.)

Beautiful bouquet marbles are obtained from the following colors;
blackish-green, 2 parts black, 1 part green; yellowish-green, 2 parts
yellow, 1 part green; light-brown, dark bluish-green as above,
scarlet-red and light ochre yellow. In this way many combinations of
color can be obtained, and it is left to the judgment of the marbler to
select colors and make the mixtures. Having succeeded in producing
beautiful marbles with few colors, it will be easy for anyone to produce
others with more colors.




MARBLED EDGES.




MARBLED EDGES.

(SEE SPECIMEN PLATES.)


Many of my colleagues are of the opinion, that marbled edges are
inferior to drawn edges, but this is a great mistake, and here we are
able to show in what directions the marbling art is able to develop to
its full glory.

The field for marbled edges is so large and prolific in the variations
of shade, that there are really no limits to its capabilities.

While making experiments in this field, by accident I came across some
edges without having an idea of the effect of the combination which so
astonished me by its beauty.

It would be endeavoring too greatly to describe the method of producing
all effective marbled-edges which came to my knowledge in my many years'
experience, I therefore name but a few which will certainly invite
imitation and study.

Marble is the design of an edge of a book, which has a ground or back
color and over which a net of veins of different colors is stretched.

For the production of marbled edges, the following preparation of size
is advisable and in general use: boil 7 quarts of water and 3-1/5 ounces
of carrageen moss, after boiling add 1 quart of cold water, in which
one ounce of common soda has been dissolved, allow it to stand for 12
hours, and filter it through a linen cloth when it will be ready for
use.

The preparation of colors is effected as with drawn marbles on a small
surface of size, but it is necessary, that the colors for marbled edges
expand more than the others. As first color, black is generally used,
which is thrown on by a brush in the same way as in making nonpareil
marble, but the other colors must be thrown on by a broom-corn whisk and
the more colors are used, the smaller must be the drops of the colors
which are thrown on the size, and it is further essential that they
should be evenly divided around. Then use gall-water which consists of
10 parts water and 1 part gall and serves to arrange the different
colors so that one color can be concentrated in one point, secondly, it
has the effect of forming a white network of veins, which enhances the
effect of the other colors, and finally, the ground color comes into
play, putting the whole carpet of colors into motion. This color is
nothing but a common nonpareil color and is used either by itself or in
a mixture with other colors.

In preparing the ground or body color, enough of gall is added so as to
slightly force the other colors into veins. An equal part of
sprinkling-water is added to it, to give it the energetical power of
spreading out essential to the formation of a beautifully veined net.
The body-color is thrown on by a medium sized bristle brush, which must
be tied near the end for this purpose. This brush is to be equally
moistened with the body color, the best would be to moisten it by the
aid of a common brush. When this is done throw the color by beating the
bristle brush on a small board upon the carpet of colors. By this
process larger or smaller specks of the body-color are formed.


THE DARK-RED MARBLE.

The marbled edges are always named from the body-color, as the latter
always occupies the largest space on the edge. For dark-red marble the
following colors are used: black, light pink (10 parts white, 1 part
safflower-carmine), light-grey (10 parts white, 1 part black),
gall-water and, finally, the ground color.

The latter is composed of 2 parts carmine-lake, 1 part black and 3 parts
sprinkling-water.


THE PLAIN-GRAY MARBLE.

This kind of marbling is the most profitable of the veined marbles
because it can be produced very rapidly.

For this purpose prepare the black color with gall in such a way, that a
drop will spread out on the size to a spot of about 5-1/2 inches in
diameter, then add an equal quantity of sprinkling water, dip a large
broom-corn whisk or a bristle-brush into the color and throw it by
beating on a board upon the size which has been cleaned off by a strip
of paper. The color appears on the size a gray color with white veins,
from which the edge can be taken.


THE BLUE MARBLE.

To produce this use the following colors; black, orange or citron
yellow, Indian red with a little black and Oriental blue, finally adding
gall water and the body color. This ground color consists of 1 part
Indigo and 1 part sprinkling water.


THE BROWN MARBLE.

This marble is one of the most common, but if the colors are well
selected as given in the following paragraph it will give a fine effect.

Black first, Havana brown second, chamois third, gall water, and, as
ground color, humin-brown with a little carmine lake and one part
sprinkling water.


THE GRAY MARBLE.

To produce this the following colors are necessary, black, dark purple,
light bluish green, gall-water and a mixture of black with sprinkling
water, by which the ground shade, gray, is obtained. A lighter or darker
gray is obtained by adding more or less sprinkling water to the ground
color.


THE OLIVE-GRAY MARBLE.

This marble has a very beautiful effect although in producing it but
three colors are used. It belongs to the so called large-veined marbles
and forms an olive grayish ground with a fine net of veins of black,
dark-brown and white. It is produced in the following way; first black
is put on with the brush, then brown is squirted on by the aid of a
broom-corn whisk and then gall water and finally the body color is
added. The body color consists of 2 parts black, 1 part green and the
necessary sprinkling-water. If the shade of the body color is too deep,
some pure water is added. For producing large veined marbles, the brush
must be well filled with color, so that in throwing on of the color
quite large drops will fall.


THE BLACK MARBLE.

It was formerly an unknown thing to produce a black marble over which a
net of light-colored veins was stretched. My investigations have
resulted in my becoming able to produce this brilliant and effective
marble.

The colors used are scarlet-red, bluish-green and gall water, the latter
representing the white, this network of veins comes out excellently from
the dark ground-tone. The scarlet-red color is first taken and must
spread out in a like way, as the black in the other two marbles. Then
follows bluish-green and gall-water and finally the body color is added.
The latter makes a special preparation necessary. Take 3/5 of an ounce
of ivory-black add 1/6 of an ounce of a thick solution of gum, grind the
whole mixture with a mixture of shellac-ammonia which has been diluted
with a little water. If the color is ground perfectly fine it is diluted
with the solution of shellac-ammonia and is ready for use. Should it
not be powerful enough to force the colors into veins, a few more drops
of gall must be added. This body color is likewise thrown on by the aid
of the large bristle brush as all other body colors.

As beautiful as this kind of marbling may be, there is a disadvantage in
its use as the body color must always be newly prepared, because on the
second day after standing it curdles, and cannot be used any more.


THE BLUISH-GRAY MARBLE.

By mixing the colors very beautiful effects may be obtained. One of
these fine marbles is the bluish-gray. To prepare it the following mode
is used; claret red (2 parts carmine-lake and 1 part black) and as body
color, Oriental blue mixed with black and sprinkling-water.


GRAY MARBLE WITH A NET OF COLORED VEINS.

To produce this the following colors are used; black, yellow,
cinnabar-red or Indian-red, Oriental blue and gall water and finally the
gray body color.

The colors are put on in the following way; first black with the brush
into a ribbon-like form, then yellow is squirted on in small drops by
means of a broom-corn whisk, then follow red, blue and gall water which
are treated like yellow, and finally, the body color is squirted on by
the aid of a whisk or the large brush. The latter forces the colors by
its great spreading power into beautiful veins, after which the edge
can be taken off. The body color consists of 1 part black and 2 parts
sprinkling water.


THE GRAYISH GREEN MARBLE.

This is one of the most beautiful specimens of marble and according to
the shading of the body color most beautiful effects can be produced by
it. The following colors are used to produce it; black, carmine-red (1
part carmine lake and 1/2 part black), gray (1 part black and 10 parts
white), finally gall-water and the body color.

The mode of producing it is the same as described before. The body color
consists of 1 part black, 2 parts of sprinkling water and as much green
as is necessary to produce the desired shade.

Before adding sprinkling water to the body color, black, only so much
gall is added that it will but slightly push the different colors thrown
on.




HAIR MARBLE.




THE HAIR MARBLE.

(SEE SPECIMEN PLATES.)


These marbles are in great use and are much liked on account of their
rapid and easy production, especially when many books are to be marbled;
they appear very elegant on account of their fineness.

For hair marbles but one or two colors are employed which are diluted
with water to 1/3 their volume. Add enough of gall to the first color so
that in throwing the same on the size it will spread sufficiently to
form a ribbon from 5 to 6 inches wide. Take a whisk and throw on the
second color in drops that are not too large and as nearly as possible,
equally distributed, then, with the bristle-brush, or sieve and brush
throw sprinkling water on the colors. In this way hair veins are formed,
showing more or less ground according to the quantity of sprinkling
water thrown on.

The size is produced for all hair-marbles alike. In the morning boil
3-1/5 ounces of carrageen moss in 7 quarts of water and after the
boiling add 1 quart of cold water, stir the whole mixture several times
and allow it to stand during the day until it is fully cooled off. In
the evening the size must be again diluted by another quart of water and
it is then filtered through a piece of linen and left to stand over
night. The next day it is ready for use. This holds good during the
summer months as the temperature of the air will just make the size
useful for this purpose. During the winter months the size must be
allowed to stand for 36 hours before use.


BLACK HAIR MARBLE.

To produce this variety of marble there is a screen or sieve necessary
as well as a wide brush having stiff bristles. By adding gall from time
to time, the black is made so expansive that a single drop will be
spread out to a spot of about 8 inches in diameter. Dip the brush into
sprinkling water, shake the brush well so that the superfluous water is
thrown out, hold the sieve above the size and move the brush quickly and
lightly over it. In this way the hair marble is finished and may be
taken off.


RED HAIR MARBLE.

For this to be produced the best color is Indian or mineral red since
all other chemical coloring substances which are bound to bodies will
usually run, on strong compression, into hair veins. Only the excellent
lakes of Munich will withstand this treatment, but the fineness of the
veins leaves much to be desired, whereas Indian red answers every
purpose.


BLUE HAIR MARBLE.

The mode of producing it is the same as applied in producing black
hair-marble, but, instead of black, Indigo is used. Indigo is the only
one among blue coloring matters that admits of the necessary expansion
for the production of hair veins without running off or gathering into
small lumps.


RED AND BLACK HAIR MARBLE.

For the production of this marble, black and Indian red are taken. The
black is first thrown upon the size as in black hair-vein marble, the
red is then treated by adding gall until a drop thrown upon the black
will spread to about 2 inches in diameter. The trial is made with a
brush, but for the purpose of producing the marble a whisk is taken, by
means of which the red is thrown upon the black in very small drops and
close to each other.


BLUISH-BROWN HAIR MARBLE.

To produce this marble Indigo and Vandyke brown are taken. The Indigo is
put on first then the Vandyke brown is thrown on by a whisk, and
finally, the carpet of colors is forced into forming veins by sprinkling
water, which is applied by aid of the brush and sieve.




Rules in regard to the Marbling Table.




RULES IN REGARD TO THE MARBLING TABLE.


The table upon which marbling is to be executed must be firm and
immovable. On it the utensils necessary to marbling are placed. The
trough, colors, gall in a closed bottle with stopper pierced by a tube,
a vessel with water, the comb, the size skimmer are all to be within
easy reach. They should be placed about in the following order; in
front, nearest to the workman and to the right, the trough, the
receptacle for the waste color and board for skimming off the size to
the left, beyond the trough the vessels in which the colors and gall are
kept, behind the first vessels containing the colors the dish containing
water, and alongside this the bottle containing gall and next to it the
comb and stylus. On the left side of the trough there must be a
sufficiently large space for the books to be marbled.




PRECAUTIONS.


Before closing the article on marbling, I will add a few words to the
precautions to be observed while marbling. Before all else, see that
the air in the room, where the marbling is to be done, is free of dust,
as the falling dust, especially in drawn marbles will form many white
spots, which spoil the effect of the marbling.

Cleanliness should always be observed, as the beauty of the marbles and
their rapid production depend on it. Protect the size from dust by a
lid, which you place on the vessel, and have a large soft sponge ready
to remove the superfluous size after each immersion of the book, by
which a rapid drying is obtained and the moisture is prohibited from
impregnating the book.




SUPPLEMENTARY REMARKS.


A NEW EXPANDING MEDIUM.

I must mention here a newly discovered medium which has been found
essential in the formation of beautiful veins in plain marble; take 1/10
quart of shellac orange, add 1/8 quart spirits of ammonia, allow the
whole to boil for 5 minutes stirring repeatedly (by which a uniform
solution of shellac in ammonia is obtained), take it from the fire and
dilute the solution with about 2 quarts of water. Throw the fluid by
means of the brush on the size and then throw on the body-color, _see
plain gray marble_. In this way beautiful white veins will appear,
which is explained by the fact, that the surface of the size is covered
with an expanding medium, which can be forced together by the
body-color, but is strong enough to hinder the union of the latter.




MARBLING OF GILT EDGES.




MARBLING OF GILT EDGES.


If gilt, silver or aluminium edges are to be marbled, burnish slightly
and moisten by a soft brush with a solution of powdered alum in hot
water which is of the consistency of a thin pap.

The marbling of the gilt-edge is then executed in the usual way before
the coating of alum is entirely dry.

After the marbling is done, water is poured over the edge until it is
entirely clean.

When the edge is completely dried it is rubbed over with a waxed rag and
is then burnished in the usual way. For marbling the usual marbling
colors are applicable, but it should here be added, that very dry edges
will not take the marbling colors readily.




MARBLING ON A LARGE SCALE.


For the purpose of marbling on a large scale especial arrangements have
to be made, and it is wonderful how elegant and practical are the
marbling rooms of large establishments. For instance the tables and
floors are of stone and cement, or of wood covered with zinc plates,
and the troughs and receptacles to take off the fluids which have been
employed are to be found in universal use. Even large iron cranes are
erected to hold the books together and lift them off, and to transport
them to the revolving drying apparatus, which can be heated.

These arrangements are in keeping with the extent of the business and
can here only be lightly passed upon.




THE UTENSILS.




THE UTENSILS.


THE MARBLING TROUGH.

The marbling trough is a long flat oblong box of about 20 inches in
length, 10 inches wide, and 1-1/4 inches deep inside, and should be
painted within with white oil-paint so that the size appears light
making the colors more readily discernible.

This trough must have inserted on one side a sloping partition of sheet
zinc so that the waste of color may be skimmed over it by aid of paper
slips or a piece of wooden board without running it over the top.

In addition to the trough containing the marbling size, a second smaller
trough or basin of 10 inches width, and 1-1/4 inches depth is necessary
for the reception of the waste of color. This is to be placed, while
marbling, immediately to the left of the first trough.


SIZE SKIMMER.

This is a piece of wooden board about 2 inches high, about 1/4 inch
thick and of the exact width of the trough. At both ends the board is
slightly wider than the trough, protruding, and while the larger part of
the board moves over the surface of the size, the projecting ends act as
guides by sliding over the rim of the trough. In this way the board is
always kept in a like position and serves to remove the air bubbles and
films and also the color waste.

Recently, strips of blotting paper 1 inch wide have been frequently and
successfully used for the removal of waste of color. They are applied in
the same manner as the board.


THE STYLUS

of wood or bone, is used for the drawing of the colors in producing
nonpareil marbles. This was described in the chapter on nonpareil edges.


THE COMB.

For the production of nonpareil marble, the comb is employed, made in
the following way; take two strips of heavy pasteboard, 12 inches long
and 2-1/2 inches wide, divide one of these exactly where the needles are
to be inserted, draw grooves so that the needles can be laid in; glue
the part in which the needles are to be laid, insert the needles in the
grooves as aforesaid, and, after drying, the second strip of pasteboard,
is glued upon the first.

The needles best adapted to comb making for use in comb marbling are
fine pearl needles of steel; they are preferable to the common pins
because they do not bend and do not offer any resistance to the size
while drawing the colors, and also because they cut the colors easily
without forming furrows.

The comb is so prepared that the pasteboard protrudes slightly at both
ends, by this the movement of the comb is defined by the rim of the
trough. It is advisable to prepare about three such combs with the
needles separated from each other about 3/32, 3/16 and 1/4 inch
respectively.


THE PEACOCK COMB.

The peacock comb consists of two common combs having strong needles
separated from one another by 1/2 inch. These two combs are put together
by means of a pasteboard frame in such a way that they can be moved 1/4
inch to the side.

Moved sideways the needles of one comb move to the centre between the
needles of the other comb, they cover each other as soon as both combs
are moved 1/4 inch in the opposite direction.


THE BRUSH.

To distribute the colors equally for drawn edges it is necessary to
divide the color around on the size as explained in the chapter on
nonpareil marble. This is almost impossible if a common brush is
employed as the drops cannot be voluntarily directed by it, I have had,
therefore, brushes made with bent bristles which make the distribution
of the drops easier.


THE BROOM-CORN WHISK.

This whisk is made of soft broom-corn about 1 to 2 inches thick. The
upper end is tightly bound with string or wire so that about 5 inches of
straw protrude. These whisks are used in producing marble-edges.


THE BRISTLE BRUSH.

A bristle brush 3 inches long and from 2 to 2-1/2 inches thick is bound
by a well waxed packing-thread about 1-1/4 inches from the top so that
the bristles are open for a length of 1-3/4 inches. This brush is very
well adapted for distributing the drops.

In marbling large lots of books, large broom-corn whisks are profitably
used for throwing on the body color or sprinkling water. Being possessed
of the above mentioned utensils which only are expensive at first,
nothing is further necessary for the production of beautiful edges.


THE BOOK CLAMP.

[Illustration]

The clamp is used to hold several books together which are to be
immersed at the same time into the marbling trough. They are of iron
entirely, are eccentrical in their movement and make a very quick
handling and an easier holding of the books possible.


APPARATUS FOR THROWING ON COLORS.

For the purpose of producing nonpareil marble an equal distribution of
color is desirable.

[Illustration]

It consists of four small color receptacles and apparatus from which
protrude needles equi-distant from each other in the form of a rake.

The throwing of marble-colors at equal distances and in equally large
drops on the size is made possible by it in a very certain and easy way
and is even a good help to the inexperienced marbler in the production
of even and exemplary edges. For the production of comb-marble on a
large scale this apparatus is especially profitable as by using it much
time is saved.

APPENDIX.


Colored AND Decorated Edges.

ACCORDING TO THE

NEWEST DISCOVERIES

BY

Eminent Specialists.




STARCHED EDGES.




STARCHED EDGES.


A great similarity to marble edges have the so called starched edges.

To produce this kind of an edge no especial practice and no important
preparations are necessary, but it permits of many varieties.

For this purpose, books already cut are placed into the hand press, and
in such a way, that the edge is horizontal.

Dissolve a small quantity of pure rice starch in water until it has the
consistency of a paste, add the different colors, which must be soluble
in water in order to color properly, such as carmine or vermilion,
cinnabar, Turkey, burnt umber, Prussian-blue, ultramarine, etc.

When the color added has been carefully united by stirring with the
solution of starch, throw, by the aid of a small whisk, the solution so
colored in drops that are not too small on the edge placed horizontally,
so that the edge is covered as uniformly as possible.

As soon as the starch thrown on is dried, sprinkle on by the aid of a
sprinkling brush and sieve, a darker color over the whole surface and
allow the whole edge to dry again, then brush off the superfluous
starch, and the colored and spotted edge will appear with veins
interspersed.

The edge will be more effective and more similar to marble, if, for
example, bluish-gray colored starch and then other starch mixed with
red, the former in small the latter in larger drops, are thrown on so
that the edge is quite well covered. Finally, a dark-brown color is
sprinkled over the whole surface.

Such edges have the effect of bluish-gray marbling imitations which are
interspersed by dark veins. If you sprinkle on fluid gold bronze i. e.
bronze finely ground in gum-arabic, instead of the dark-brown color, you
obtain the celebrated gold veined edge in connection with the starched
edge.

Unsized paper is the best for producing starch edges because it quickly
absorbs the moisture of the starch and color.

To sized paper the color does not stick so readily and for that reason
often runs together. To prevent this, moisten the edge before applying
the starch color, with some ox-gall, and allow the first color to dry
thoroughly before applying the second.




The Production of Colored Edges.




THE PRODUCTION OF COLORED EDGES.


The beautiful marbled edges have nearly driven every other kind of edges
entirely out of the market.

Aside from marbled edges, colored edges are mostly used. They will keep
their place on account of the simplicity of their production and their
bright coloring effects.

Red-edges, especially when prettily made, give a dignified aspect to a
book, so to speak, and they are therefore frequently and properly
employed.

Our highly developed color industry offers to us a very great number of
red colors, especially the carmine, vermilions and cinnabars, all of
great value in our trade. These colors will not fade, the former carmine
possesses great intensity, and cinnabar has the power to obliterate
colors underlying it.

When cheap colored edges are to be produced even aniline colors can be
taken into consideration. For instance, eosine is a red color, which
used by itself or in combination with carmine and other red colors makes
a beautiful color for edges but it will fade on exposure to the sun.

The preparation of these colors is of importance. Genuine carmine
should, after the different pieces have been crushed, be ground for a
short time with a little spirits of ammonia and then allowed to stand
until completely dissolved. To dilute it, a thin solution of gum or
water (the best is rain water) may be used. If too much spirits of
ammonia has been employed the color will assume a bluish hue.

The heavy cinnabar makes a more powerful binding medium necessary, the
best being a paste of starch or a solution of gum-arabic. Careful
crushing and a thorough grinding of the color are essential.

Genuine carmine has a red color with a slight bluish cast whereas
cinnabar approaches yellowish-red. A pleasing, pure red can be produced
by using Turkish red. A bright lustrous shade is obtained by adding some
red aniline color.

If edges have to be colored blue, use ultramarine blue for dark, or
cobalt blue for light.

Both colors must be mixed with gum-arabic or paste by grinding, and, if
necessary, be diluted with water.

To produce yellow edges, chrome yellow is mostly used. It is for sale in
all different shades from the brightest greenish-yellow, to the darkest
orange-yellow.

In using it, like any other mineral or earth colors, it is finely ground
and mixed, for use, with paste.

Green edges are often produced by using Schweinfurt's green or
silk-green. By mixing light chrome-yellow with cobalt-blue, a beautiful
rich green results.

For brown and black the well known colors umber, sepia, vegetable
lamp-black, drop ivory-black and others are employed.

The color for producing violet edges can be best obtained by mixing
cobalt-blue with Turkish-red or carmine.

It is always the most essential part of the process to grind the color
uniformly with the paste, if it is desirable to obtain an edge of the
same intensity of color.

A peeling off of the color while the edges are being burnished is due to
a lack of paste, or of a too great consistency or too insufficient
fineness of the color.

Recently our industry has taken this article in hand and furnishes a
large number of beautiful, cheap and well prepared colors for producing
edges which can be bought more profitably than they can be laboriously
made.

As all colored edges, to give a beautiful effect, must be burnished
after coloring, it is advisable to execute the coloring while the books
are in the press, place the books after their front edges have been cut,
by the aid of gilding boards into the hand-press and with a soft brush
apply the color thinly. If the color does not thoroughly cover on one
application, the operation must be repeated after the first coat has
completely dried. When a uniform color is obtained allow the edge to
dry in the press and then burnish it well with a broad burnisher.

By using a little wax you will render the burnishing more successful.

The color will sometimes enter into unsized or wood paper
notwithstanding heavy pressure.

To avoid this the edges must be moistened with a thin paste to which
some alum is added. It is still better to use the grounding substance
manufactured by William Leo, of Stuttgart.

If beautiful edges are to be produced, then, in cutting the book it is
necessary to see that the knife of the machine is free from nicks, so
that the cut is clean and smooth.

At the fore-edge of the book there will always appear some small parts
of the different sheets protruding slightly. If this is to be overcome,
these edges are to be treated as hollow edges which means that they must
be scraped hollow before coloring and must be burnished with the
round-burnisher.

The use of colored edges is always left to individual taste. The
following rule may be of some advantage; colored edges must have a
binding of an opposite color. A red edge will appear to most advantage
with a white, gray, dull-green, dark-brown or antique binding.

Bindings of a reddish-brown color would lose in their general aspect by
the employment of a red edge.

If books with red edges are to be covered with red, it is then essential
that the colors of both are corresponding.




GILT EDGES.




GILT EDGES.


In the production of gilt edges, there have not been any essential
improvements noticed.

If the gilt-edge is to-day produced more beautifully and perfectly than
formerly, it is due in part to a more extensive experience and practice,
and also to the excellent quality of gold-leaf now on the market.

No edges contribute so greatly to the generally elegant appearance of a
book as gilt-edges; they are lustrous and rich and are more pleasing to
the eyes of most men than the plain and unseemly colored edges, though a
great deal of trouble and industry is necessary to the production of
these beautiful effects.

A principal condition in the production of gilt-edges is the utmost
cleanliness and skill in executing the necessary manipulations.

In cutting the book, great care must be taken that the cuts are entirely
smooth and clean, without any blemish. Sharp knifes are therefore
indispensable in this kind of work.

Gilt-edges demand an entirely smooth surface which is only produced by
carefully scraping the surface with a steel scraper. The edge must be
scraped perfectly smooth so as not to show the marks of the knife in
cutting or those of the scraper. To this end the books, the edges of
which have already been cut, are placed between gilding-boards in hand
presses in such a way that the fore-edge protrudes but slightly over the
cheeks of the press. After the press has been tightly drawn down and has
been fastened firmly, the scraping of the edges can be begun. When this
tiresome work has been finished, and an entirely smooth surface has been
obtained, the surface is moistened with a paste-water and rubbed dry
with clean paper-shavings. By this grinding and rubbing off, the edge
becomes shiny and dry, and gains in the power of resistance, which is of
great importance for the burnishing that occurs in the later stage of
gilt-edging.

The smooth, hard ground of paste is not sufficient for the production of
gilt-edges that are perfectly beautiful.

They must be colored lightly with bolus or chalk, (the most adapted to
this work is the finely washed Armenian bole.)

The book-binders supply establishment of Wm. Leo, of Stuttgart, provides
an excellent article.

This bole after it has been finely ground and scraped, must be mixed
with a solution of albumen (the white of the egg) such as is used for
laying on gold leaf, and must be spread lightly and evenly over the edge
by a fine broad hair brush or with a fine sponge, to prohibit the
scaling off of the gold.

This process must be repeated. The ground of bole gives the gilt-edge a
dark shade and a high lustre and glow.

When the grounding of bole is entirely dry, and all the parts clinging
to the edge have been carefully brushed off, we begin the most difficult
part in the production of gilt-edges, the laying on of the gold.

As binding medium between the gold-leaf and the edge of the book, a
solution of the white of the egg is used. Carefully separate the white
of the egg from the yolk and dilute the same with 1 pint of water and
stir until a perfect mixture of the two results. After this fluid has
stood for several hours, it becomes perfectly clear, the froth of the
egg floating upon the surface is removed and the solution is ready for
use.

Paper containing lime makes a stronger size necessary.

To transfer the gold-leaf, which has been cut on the gold cushion to the
size required, on to the edge, a rectangular light wooden frame of wood
or paste board is used, across which two horse hairs or silk threads are
stretched parallel to the long sides of the rectangle in such a way that
they can be moved at will nearer to or farther from one another.




LAYING-ON APPARATUS.




THE LAYING-ON APPARATUS.


[Illustration]

Much more practical than this frame is the laying-on apparatus. It can
be more easily and securely handled, and the laying on strings can be
more easily set.

By means of this simple instrument the sheets of gold-leaf which are
laying ready on the cushion and which must be so wide that they not only
cover the edge entirely but also protrude about 1/8 inch beyond the
gilding boards are transferred on to the sized edge. The sizing must be
done with a soft camels hair brush, not too thin and it is essential
that the gilding boards also become moistened.

The strings of this laying on apparatus or of the frame must be so far
distant from each other that they reach from gilding board to gilding
board.

The sheets of gold leaf that have been cut before must then be carefully
transferred, one by one, on the sized edge.

To make the gold-leaf adhere to the strings of the frame, the strings
are rubbed slightly upon the hair of the head by which means they absorb
sufficient fatty substance to hold the light sheets of gold.

If after the gold is laid on it should contain any imperfections or
breaks, other portions must be applied to these abrasions. The press is
then placed aside until the edge is entirely dry. In treating the upper
and lower edges i. e. after the book has been rounded, care must always
be taken that in sizing, not too much moisture impregnates the back part
of the edges as there is no pressure to prevent the size from running
in.

If the gilt-edge is to have lustre and glow by burnishing, great care
must be taken to dry the edge well.

An edge, which is not sufficiently dried, will exhibit breaks in the
gold on burnishing, and an edge which is too dry will never have the
desired lustre.

It is impossible to name the time within which gilt-edges become dry.
This depends upon the temperature of the room, the quality of the paper
in the book and on the quantity of albumen solution which has been put
on the edge.

The safest way to find out whether the edge is dry or not is to blow
upon it. If the lustre of the gold is dimmed for several seconds, the
edge is still too moist, but if the cloud vanishes immediately the edge
is sufficiently dry.

We can also determine by a careful easy burnishing whether the edge is
dry enough to be worked further.

The burnishing should always be executed with a flat agate burnisher,
and afterwards followed by a flat blood stone. The burnishing should be
commenced by covering the edge with a piece of thin smooth paper that
has been rubbed with wax.

First burnish the gold laid on slightly, afterwards continue with greater
force.

By this the edge acquires a uniformly dull aspect but a strong union of
gold and paper is thereby established.

Before beginning the real burnishing rub the edge with a soft rag upon
which a small quantity of pure white wax has been rubbed. This thin film
of wax renders the burnishing much easier because the burnisher is made
to glide more readily and securely over the edge.

The burnishing must first be executed lightly and then with greater
force.

The repairing of gilt-edges should be avoided as much as possible.
Should it become, nevertheless, unavoidable, then moisten the spots to
be repaired with the solution of albumen described above, lay on gold
leaf, allow the spots which you wish to repair to become dry, rub off
and burnish as usual.

In place of albumen solution, sulphuric ether can be used for repairing.
The latter has the advantage of causing the spots so repaired to become
dry immediately, but it causes a lighter spot to appear in the
gilt-edge. Alcohol, lightly applied, can also be used for this purpose
and with more security. The gilding of the hollow edge is produced in
the same way as that of the level edge. In scraping, curved scrapers are
used. To lay on the gold use the frame. Transfer the gold leaf from the
gold cushion to the strings of the frame, then carefully bring these
strings closer to each other, so that the gold leaf is no longer
straight, but somewhat hanging down. Then transfer it to the sized edge.

To burnish give the hand press an oblique position, making the front of
the press lay lower than the rear so that one half of the hollow edge
has a more horizontal position, and burnish it with a flat burnisher in
the same manner as the level edge. This being done, the remainder of the
hollow edge is likewise treated at the same time, giving the press a
different position. Only after the edge has been burnished on both sides
with a flat burnisher, is the round burnisher (tooth) used to finish the
hollow edge on its length.

Gilding on a colored, especially a red edge is very effective. These
gilt-edges with an underlying red-edge are of English origin and are
used generally for Bibles and prayer books. The fore edge of such books
is colored in an oblique position of the edge, and they therefore have
not a golden, but a red effect, when opened.

The production of such edges demands a certain experience, if the
coloring of the fore-edge shall have a correct effect, and the leaves of
the book are to be as little as possible impregnated by the color.

This color must be mixed like any other edge colors with gum-arabic,
starch paste or the white of an egg.

All etching substances, such as spirits of ammonia, must be avoided as
they often cause the color to soak too deeply into the paper.

In manipulating the fore edge, open the book slightly, fasten the edge
in this oblique position and then lightly apply the color.

When this has thoroughly dried, open the edge towards the other side and
continue with the same procedure.

The different leaves are thus not only colored at the edges proper, but
the color has also been slightly imparted to the upper and lower sides
of the leaves at the same time, and for this reason the edge of the
book, after it is gilded, appears reddish when the book is opened out.

The upper and lower edges must be treated as all other colored edges.

In producing the gilt-edge in the way above mentioned, rubbing off with
paste and grounding with bole must of course not be employed.

The production of edges with metal leaf or aluminium, is under the same
rules as for gilt edges.

To produce silver edges, a sizing material of a solution of gelatine
(one half of a gelatine cake to one cup of water) is used as a surrogate
to the albumen. This can also be employed in the laying on of aluminium.

For base metal leaf care should be taken that a soft, thin article is
used, the one of a light hue is more pliable on account of the larger
quantity of tin contained in it than is in the darker copper one.

The more pliable French aluminium is preferable to the brittle German
article.

If gilt-edges are to be produced upon unsized paper, the edges must be
sized with a solution of gelatine.




Colored Edges with Front and End Gilding.




COLORED EDGES WITH FRONT AND END GILDING.


The effect of edges gilt front and back with marbling between is
beautiful. This edge is especially applicable to books of large size.

The plain red-edge (carmine) and every marbled edge can be used in this
connection.

Antique marbles are greatly adapted to this kind of book-edge
decoration.

[Illustration]

The production of these edges does not offer any especial technical
difficulties. The book block must be treated as a hollow edge and must
be scraped and then decorated with antique marbling or red color.

This having been done, insert the book into the hand-press and mark
correctly how far the gilding is to be done.

To put on the gold, a solution of albumen is applied to the spots to be
gilded and then a good and substantial gold leaf is laid on. As soon as
the edge is dry, burnish as any other gilt-edge.

A fine chased pearl line at the meeting of the two edges, will greatly
enhance the effect of this beautiful edge.




The Punched or Chased Gilt-Edge.




THE PUNCHED OR CHASED GILT-EDGE.


The procedure by which the effect of the gilt-edge is enhanced and
enlivened by chasing is very old, in fact nearly as old as the gilt-edge
itself. It has been driven out of the market as many another thing by
over production and has finally become obsolete. In recent times it has
been taken up again on account of the progress in the industrial arts
and is now very highly esteemed. The design for such a decoration of
gilt-edges should always be prepared by an artist and should always
conform strictly to the decorations of the cover.

Technically, the production of such edges is not difficult. Some talent
for drawing and a sure hand are necessary, but the artist is repaid for
his labor by the interest he derives from the execution of such kind of
work.

There are two ways of producing them.

The first makes the ornament appear bright, while the ground remains
dull, in the other the dull ornament appears on the shining ground
surface.

The first is the more effective and the more easily produced.

The gilt-edge is here to be treated like every other plain gilt-edge, to
produce dull ground, burnish with a piece of paper between the book edge
and the burnisher.




CHASED EDGES.




[Illustration: Fd. Tondorf ClichË,--Property of OTTO SPAMER.]

CHASED EDGES.


Transfer the design on thin tissue paper, lay the paper carefully upon
the edge of the book placed in the press so that design and edge tally
perfectly, and fasten the paper by pasting it on the gilding boards.

If you now by the aid of a dull awl or a pin trace the design of the
tissue paper on the edge, it will appear and will be the gilder's guide.
When this has been done with all necessary care, remove the paper and
burnish the parts of the edge between the tracings by means of a small,
pointed burnisher.

This alone relieves the ornament from the dull gilt ground.

The full effect of such edges will be imparted when the outlines of the
ornaments are pressed in. To do this, fine steel stencils or stamps are
best used, the same as are used for fine leather work. These stamps and
the above mentioned agate burnishers can be obtained from Wm. Leo,
Stuttgart.

Take the point stamp in one hand and a light hammer in the other and
with an easy, equal, hammering make dot after dot of the marked pattern.
If the dull ground is then profusely marked with the small pearl stamp
as shown in the illustration, the effect of such edges leaves nothing to
be desired.

The effect is still more surprising when the ornaments are produced in
gold of a different hue or of silver or color. In the former case the
ornaments are carefully penciled in with albumen solution, gold of a
lighter hue, silver or aluminium is put on, and, when completely dried,
is burnished.

Colored ornaments are likewise scraped out and then produced by
painting.

It is a question though, whether the total effect of this last named is
a refined one.




BRONZED EDGES.




THE BRONZED EDGE.


Produced by printing over colored edges. It is certainly proper to
endeavor to brighten colored edges by spreading on bronzed color.

That this process has fallen more or less into disuse is probably due to
the tiresome labor necessary for the making of such edges. It gives us
the possibility of producing manifold changes in edges because silver or
gold ornaments can be put on any color as well as on the white edge.

We have here the possibility of adapting the design of the edge to that
of the cover, which under other conditions can only be done with chased
edges.

It is an erroneous idea to disfigure genuine gilt-edge by putting on
bronze ornaments. The base and perishable bronze can never be the
correct material to brighten the effect of genuine gold.

The bronzing of edges can only be applied to colored or white edges but
not to genuine gilt-edges.

For the production of bronzed edges, the following articles are
necessary.

First, Engraved plate or Cliche representing the ornament with which the
edge is to be decorated.

Second, Thin leaves of roller composition for the transfer of the
ornament from the plate on to the edge.

Third, Roller for rolling in the gravure.

Fourth, Thick, fluid, strong amber-lacquer, as binding medium between
the bronze and the color of the edge.

The following rules should be observed.

The treatment of the book block is similar to that of the hollow edge,
therefore the book, after the fore edge has been cut and rounded must be
scraped hollow.

As colors for the edge, the above mentioned colors, carmine, cinnabar,
cobalt-blue and others are recommendable.

As binding medium a strong albumen or gum-arabic should be used. Aniline
colors can be used for this purpose, but they must be dissolved in
alcohol.

Such edges have a bewitching appearance if they are made in the same
shade of color as the cover, but they render a certain practice in the
mixture of colors necessary.

The coloring and burnishing of the edges is executed in the same manner
as described in the article upon the production of colored edges. After
the burnishing of the edge is executed, the time has arrived to imprint
the ornament upon it.

Cut off of the thin leaf of roller composition, a strip slightly larger
than the surface of the edge. Put a little of the thick, fluid
amber-lacquer upon the roller, and move the roller forward and back on a
smooth stone (marble slab) until the lacquer is equally spread out over
the surface of the roller. When this is done, the gravure can be rolled
over by aid of this roller.

The thin strip of roller composition is then carefully placed on the
gravure, pressed on lightly and evenly with cotton wadding or a soft
rag. By this means the ornament of the gravure is transferred to the
roller composition.

To transfer this ornament on to the surface of the edge, it is necessary
to lay the strip of roller composition carefully on the edge and
carefully and evenly press it on.

The bronze is not to be put on to the edge on which the design is
printed before the lacquer is quite dry, only then can the blurring of
the ornament be avoided and the bronze be made to retain its specific
metallic lustre.

After the lapse of several hours, the bronze will be dry, and then the
cleaning of the edge is done with soft cotton wadding.

The strips of roller composition so used must be cleaned immediately
after use with clean turpentine and, after they are dried, they can be
again used.

In order to produce the necessary transfer strips use only the best
English roller composition. Cut this mass into small pieces, place them
in an earthen vessel, subject them to a moderate heat until they become
entirely fluid and pour the fluid mass on a piece of glass or a smooth
sheet of tin. After this has cooled it should be carefully removed. To
render this easier, the plate of glass or the piece of tin should be
lubricated with some fine oil.




Producing Marble on Gilt Edges.




PRODUCING MARBLE ON GILT EDGES.


If gilt, silver or aluminium edges are to be marbled, they must be
thoroughly dried, burnished slightly and rubbed off with a small piece
of linen, silk or leather, and any blemishes or spots from which the
gold or other metal has blistered must be repaired.

The dull gilt-edge is now to be moistened by means of a soft brush with
a solution of powdered alum in hot water after this has formed a thin
paste.

The marbling of the gilt-edge is executed in the usual way, before the
layer of alum is entirely dried. After the completion of the marbling
the edge must be washed with water until it is entirely clean.

After the edge has become dry, it is rubbed with a waxed rag and
burnished over.

For marbling, the common marbling colors can be used.

It remains only to add that too dry edges do not take marbling colors
readily.

*** END OF THE PROJECT GUTENBERG EBOOK THE PROGRESS OF THE MARBLING ART ***

Updated editions will replace the previous one--the old editions will
be renamed.

Creating the works from print editions not protected by U.S. copyright
law means that no one owns a United States copyright in these works,
so the Foundation (and you!) can copy and distribute it in the
United States without permission and without paying copyright
royalties. Special rules, set forth in the General Terms of Use part
of this license, apply to copying and distributing Project
Gutenberg-tm electronic works to protect the PROJECT GUTENBERG-tm
concept and trademark. Project Gutenberg is a registered trademark,
and may not be used if you charge for an eBook, except by following
the terms of the trademark license, including paying royalties for use
of the Project Gutenberg trademark. If you do not charge anything for
copies of this eBook, complying with the trademark license is very
easy. You may use this eBook for nearly any purpose such as creation
of derivative works, reports, performances and research. Project
Gutenberg eBooks may be modified and printed and given away--you may
do practically ANYTHING in the United States with eBooks not protected
by U.S. copyright law. Redistribution is subject to the trademark
license, especially commercial redistribution.

1.E.8.

1.B. "Project Gutenberg" is a registered trademark. It may only be
used on or associated in any way with an electronic work by people who
agree to be bound by the terms of this agreement. There are a few
things that you can do with most Project Gutenberg-tm electronic works
even without complying with the full terms of this agreement. See
paragraph 1.C below. There are a lot of things you can do with Project
Gutenberg-tm electronic works if you follow the terms of this
agreement and help preserve free future access to Project Gutenberg-tm
electronic works. See paragraph 1.E below.

1.C. The Project Gutenberg Literary Archive Foundation ("the
Foundation" or PGLAF), owns a compilation copyright in the collection
of Project Gutenberg-tm electronic works. Nearly all the individual
works in the collection are in the public domain in the United
States. If an individual work is unprotected by copyright law in the
United States and you are located in the United States, we do not
claim a right to prevent you from copying, distributing, performing,
displaying or creating derivative works based on the work as long as
all references to Project Gutenberg are removed. Of course, we hope
that you will support the Project Gutenberg-tm mission of promoting
free access to electronic works by freely sharing Project Gutenberg-tm
works in compliance with the terms of this agreement for keeping the
Project Gutenberg-tm name associated with the work. You can easily
comply with the terms of this agreement by keeping this work in the
same format with its attached full Project Gutenberg-tm License when
you share it without charge with others.

1.D. The copyright laws of the place where you are located also govern
what you can do with this work. Copyright laws in most countries are
in a constant state of change. If you are outside the United States,
check the laws of your country in addition to the terms of this
agreement before downloading, copying, displaying, performing,
distributing or creating derivative works based on this work or any
other Project Gutenberg-tm work. The Foundation makes no
representations concerning the copyright status of any work in any
country other than the United States.

1.E. Unless you have removed all references to Project Gutenberg:

1.E.1. The following sentence, with active links to, or other
immediate access to, the full Project Gutenberg-tm License must appear
prominently whenever any copy of a Project Gutenberg-tm work (any work
on which the phrase "Project Gutenberg" appears, or with which the
phrase "Project Gutenberg" is associated) is accessed, displayed,
performed, viewed, copied or distributed:

  This eBook is for the use of anyone anywhere in the United States and
  most other parts of the world at no cost and with almost no
  restrictions whatsoever. You may copy it, give it away or re-use it
  under the terms of the Project Gutenberg License included with this
  eBook or online at www.gutenberg.org. If you are not located in the
  United States, you will have to check the laws of the country where
  you are located before using this eBook.

1.E.2. If an individual Project Gutenberg-tm electronic work is
derived from texts not protected by U.S. copyright law (does not
contain a notice indicating that it is posted with permission of the
copyright holder), the work can be copied and distributed to anyone in
the United States without paying any fees or charges. If you are
redistributing or providing access to a work with the phrase "Project
Gutenberg" associated with or appearing on the work, you must comply
either with the requirements of paragraphs 1.E.1 through 1.E.7 or
obtain permission for the use of the work and the Project Gutenberg-tm
trademark as set forth in paragraphs 1.E.8 or 1.E.9.

1.E.3. If an individual Project Gutenberg-tm electronic work is posted
with the permission of the copyright holder, your use and distribution
must comply with both paragraphs 1.E.1 through 1.E.7 and any
additional terms imposed by the copyright holder. Additional terms
will be linked to the Project Gutenberg-tm License for all works
posted with the permission of the copyright holder found at the
beginning of this work.

1.E.4. Do not unlink or detach or remove the full Project Gutenberg-tm
License terms from this work, or any files containing a part of this
work or any other work associated with Project Gutenberg-tm.

1.E.5. Do not copy, display, perform, distribute or redistribute this
electronic work, or any part of this electronic work, without
prominently displaying the sentence set forth in paragraph 1.E.1 with
active links or immediate access to the full terms of the Project
Gutenberg-tm License.

1.E.6. You may convert to and distribute this work in any binary,
compressed, marked up, nonproprietary or proprietary form, including
any word processing or hypertext form. However, if you provide access
to or distribute copies of a Project Gutenberg-tm work in a format
other than "Plain Vanilla ASCII" or other format used in the official
version posted on the official Project Gutenberg-tm website
(www.gutenberg.org), you must, at no additional cost, fee or expense
to the user, provide a copy, a means of exporting a copy, or a means
of obtaining a copy upon request, of the work in its original "Plain
Vanilla ASCII" or other form. Any alternate format must include the
full Project Gutenberg-tm License as specified in paragraph 1.E.1.

1.E.7. Do not charge a fee for access to, viewing, displaying,
performing, copying or distributing any Project Gutenberg-tm works
unless you comply with paragraph 1.E.8 or 1.E.9.

1.E.8. You may charge a reasonable fee for copies of or providing
access to or distributing Project Gutenberg-tm electronic works
provided that:

* You pay a royalty fee of 20% of the gross profits you derive from
  the use of Project Gutenberg-tm works calculated using the method
  you already use to calculate your applicable taxes. The fee is owed
  to the owner of the Project Gutenberg-tm trademark, but he has
  agreed to donate royalties under this paragraph to the Project
  Gutenberg Literary Archive Foundation. Royalty payments must be paid
  within 60 days following each date on which you prepare (or are
  legally required to prepare) your periodic tax returns. Royalty
  payments should be clearly marked as such and sent to the Project
  Gutenberg Literary Archive Foundation at the address specified in
  Section 4, "Information about donations to the Project Gutenberg
  Literary Archive Foundation."

* You provide a full refund of any money paid by a user who notifies
  you in writing (or by e-mail) within 30 days of receipt that s/he
  does not agree to the terms of the full Project Gutenberg-tm
  License. You must require such a user to return or destroy all
  copies of the works possessed in a physical medium and discontinue
  all use of and all access to other copies of Project Gutenberg-tm
  works.

* You provide, in accordance with paragraph 1.F.3, a full refund of
  any money paid for a work or a replacement copy, if a defect in the
  electronic work is discovered and reported to you within 90 days of
  receipt of the work.

* You comply with all other terms of this agreement for free
  distribution of Project Gutenberg-tm works.

1.E.9. If you wish to charge a fee or distribute a Project
Gutenberg-tm electronic work or group of works on different terms than
are set forth in this agreement, you must obtain permission in writing
from the Project Gutenberg Literary Archive Foundation, the manager of
the Project Gutenberg-tm trademark. Contact the Foundation as set
forth in Section 3 below.

1.F.

1.F.1. Project Gutenberg volunteers and employees expend considerable
effort to identify, do copyright research on, transcribe and proofread
works not protected by U.S. copyright law in creating the Project
Gutenberg-tm collection. Despite these efforts, Project Gutenberg-tm
electronic works, and the medium on which they may be stored, may
contain "Defects," such as, but not limited to, incomplete, inaccurate
or corrupt data, transcription errors, a copyright or other
intellectual property infringement, a defective or damaged disk or
other medium, a computer virus, or computer codes that damage or
cannot be read by your equipment.

1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right
of Replacement or Refund" described in paragraph 1.F.3, the Project
Gutenberg Literary Archive Foundation, the owner of the Project
Gutenberg-tm trademark, and any other party distributing a Project
Gutenberg-tm electronic work under this agreement, disclaim all
liability to you for damages, costs and expenses, including legal
fees. YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT
LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE
PROVIDED IN PARAGRAPH 1.F.3. YOU AGREE THAT THE FOUNDATION, THE
TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE
LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR
INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH
DAMAGE.

1.F.3. LIMITED RIGHT OF REPLACEMENT OR REFUND - If you discover a
defect in this electronic work within 90 days of receiving it, you can
receive a refund of the money (if any) you paid for it by sending a
written explanation to the person you received the work from. If you
received the work on a physical medium, you must return the medium
with your written explanation. The person or entity that provided you
with the defective work may elect to provide a replacement copy in
lieu of a refund. If you received the work electronically, the person
or entity providing it to you may choose to give you a second
opportunity to receive the work electronically in lieu of a refund. If
the second copy is also defective, you may demand a refund in writing
without further opportunities to fix the problem.

1.F.4. Except for the limited right of replacement or refund set forth
in paragraph 1.F.3, this work is provided to you 'AS-IS', WITH NO
OTHER WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT
LIMITED TO WARRANTIES OF MERCHANTABILITY OR FITNESS FOR ANY PURPOSE.

1.F.5. Some states do not allow disclaimers of certain implied
warranties or the exclusion or limitation of certain types of
damages. If any disclaimer or limitation set forth in this agreement
violates the law of the state applicable to this agreement, the
agreement shall be interpreted to make the maximum disclaimer or
limitation permitted by the applicable state law. The invalidity or
unenforceability of any provision of this agreement shall not void the
remaining provisions.

1.F.6. INDEMNITY - You agree to indemnify and hold the Foundation, the
trademark owner, any agent or employee of the Foundation, anyone
providing copies of Project Gutenberg-tm electronic works in
accordance with this agreement, and any volunteers associated with the
production, promotion and distribution of Project Gutenberg-tm
electronic works, harmless from all liability, costs and expenses,
including legal fees, that arise directly or indirectly from any of
the following which you do or cause to occur: (a) distribution of this
or any Project Gutenberg-tm work, (b) alteration, modification, or
additions or deletions to any Project Gutenberg-tm work, and (c) any
Defect you cause.

Section 2. Information about the Mission of Project Gutenberg-tm

Project Gutenberg-tm is synonymous with the free distribution of
electronic works in formats readable by the widest variety of
computers including obsolete, old, middle-aged and new computers. It
exists because of the efforts of hundreds of volunteers and donations
from people in all walks of life.

Volunteers and financial support to provide volunteers with the
assistance they need are critical to reaching Project Gutenberg-tm's
goals and ensuring that the Project Gutenberg-tm collection will
remain freely available for generations to come. In 2001, the Project
Gutenberg Literary Archive Foundation was created to provide a secure
and permanent future for Project Gutenberg-tm and future
generations. To learn more about the Project Gutenberg Literary
Archive Foundation and how your efforts and donations can help, see
Sections 3 and 4 and the Foundation information page at
www.gutenberg.org

Section 3. Information about the Project Gutenberg Literary
Archive Foundation

The Project Gutenberg Literary Archive Foundation is a non-profit
501(c)(3) educational corporation organized under the laws of the
state of Mississippi and granted tax exempt status by the Internal
Revenue Service. The Foundation's EIN or federal tax identification
number is 64-6221541. Contributions to the Project Gutenberg Literary
Archive Foundation are tax deductible to the full extent permitted by
U.S. federal laws and your state's laws.

The Foundation's business office is located at 809 North 1500 West,
Salt Lake City, UT 84116, (801) 596-1887. Email contact links and up
to date contact information can be found at the Foundation's website
and official page at www.gutenberg.org/contact

Section 4. Information about Donations to the Project Gutenberg
Literary Archive Foundation

Project Gutenberg-tm depends upon and cannot survive without
widespread public support and donations to carry out its mission of
increasing the number of public domain and licensed works that can be
freely distributed in machine-readable form accessible by the widest
array of equipment including outdated equipment. Many small donations
($1 to $5,000) are particularly important to maintaining tax exempt
status with the IRS.

The Foundation is committed to complying with the laws regulating
charities and charitable donations in all 50 states of the United
States. Compliance requirements are not uniform and it takes a
considerable effort, much paperwork and many fees to meet and keep up
with these requirements. We do not solicit donations in locations
where we have not received written confirmation of compliance. To SEND
DONATIONS or determine the status of compliance for any particular
state visit www.gutenberg.org/donate

While we cannot and do not solicit contributions from states where we
have not met the solicitation requirements, we know of no prohibition
against accepting unsolicited donations from donors in such states who
approach us with offers to donate.

International donations are gratefully accepted, but we cannot make
any statements concerning tax treatment of donations received from
outside the United States. U.S. laws alone swamp our small staff.

Please check the Project Gutenberg web pages for current donation
methods and addresses. Donations are accepted in a number of other
ways including checks, online payments and credit card donations. To
donate, please visit: www.gutenberg.org/donate

Section 5. General Information About Project Gutenberg-tm electronic works

Professor Michael S. Hart was the originator of the Project
Gutenberg-tm concept of a library of electronic works that could be
freely shared with anyone. For forty years, he produced and
distributed Project Gutenberg-tm eBooks with only a loose network of
volunteer support.

Project Gutenberg-tm eBooks are often created from several printed
editions, all of which are confirmed as not protected by copyright in
the U.S. unless a copyright notice is included. Thus, we do not
necessarily keep eBooks in compliance with any particular paper
edition.

Most people start at our website which has the main PG search
facility: www.gutenberg.org

This website includes information about Project Gutenberg-tm,
including how to make donations to the Project Gutenberg Literary
Archive Foundation, how to help produce our new eBooks, and how to
subscribe to our email newsletter to hear about new eBooks.
