The Progress of the Marbling Art.
by Josef Halfer.
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 ma.s.s 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 l.u.s.tre. 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 a.r.s.enic. 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 h.o.m.ogeneous and the smaller the viscosity of the mucilage of the sizing, the better for comb, peac.o.c.k 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 pa.s.sed. 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 pa.s.ses 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.
