A Treatise on Etching Part 1

A Treatise on Etching.

by Maxime Lalanne.

PREFACE.

So much interest has of late years been shown in England in the art of etching, that it seems hardly necessary to apologize for bringing out an English edition of a work on the subject from the pen of an artist whom a weighty English authority has p.r.o.nounced to be the best French landscape-etcher of the day. It might be urged, indeed, that more than enough has already been written concerning the technical as well as the aesthetic side of etching. But this objection is sufficiently met by the statement of the fact that there is no other work of the kind in which the processes involved are described in so plain and lucid a manner as in M. Lalanne's admirable "_Traite de la Gravure a l'Eau-forte_." In the laudable endeavor to be complete, most of the similar books now extant err in loading down the subject with a complicated ma.s.s of detail which is more apt to frighten the beginner than to aid him. M. Lalanne's _Treatise_, on the contrary, is as simple as a good work of art.

It may, however, be inc.u.mbent upon me to offer a few words of excuse concerning my own connection with the bringing out of this translation; for, at first sight, it will, no doubt, appear the height of presumption, especially on the part of one who is not himself a practising artist, to add an introductory chapter and notes to the work of a consummate master on his favorite art. But what I have done has not, in any way, been dictated by the spirit of presumption. The reasons which induced me to make the additions may be stated as follows.

It is a most difficult feat for one who has thoroughly mastered an accomplishment, and has practised it successfully for a lifetime, to lower himself to the level of those who are absolutely uninformed. A master is apt to forget that he himself had to learn certain things which, to him, seem to be self-evident, and he therefore takes it for granted that they _are_ self-evident. A practised etcher thinks nothing of handling his acid, grounding and smoking his plate, and all the other little tricks of the craft which, to a beginner, are quite worrying and exciting. It seemed to me best, therefore, to acquaint the student with these purely technical difficulties, without complicating his first attempts by artistic considerations, and hence the origin of the "Introductory Chapter." Very naturally I was compelled, in this chapter, to go over much of the ground covered by the _Treatise_ itself. But the diligent student, who remembers that "Repet.i.tion is the mother of learning," will not look upon the time thus occupied as wasted.

The notes are, perhaps, still more easily explained. M. Lalanne very rarely stops to inform his reader how the various requisites may be made. Writing, as he did, at and for Paris, there was, indeed, no reason for thus enc.u.mbering his book; for in Paris the Veuve Cadart is always ready to supply all the wants of the etcher. For a London reader, Mr.

Charles Roberson, of 99 Long Acre, whom Mr. Hamerton has so well--and very properly--advertised, is ready to perform the same kind office. But for those who live away from the great centres of society, it may oftentimes be necessary either to forego the fascinations of etching, or else to provide the materials with their own hands. For the benefit of such persons, I have thought it advisable to describe, in the notes, the simplest and cheapest methods of making the tools and utensils which are needed in the execution of M. Lalanne's precepts.

By the arrangement of the paragraphs which I have ventured to introduce, M. Lalanne's pleasant little book has, perhaps, lost something of its vivacity and freshness, especially in the fifth chapter. But this dull, methodical order will be found, I hope, to add to the convenience of the work as a book of reference, which, according to M. Lalanne's own statement, is, after all, its main object.

It is due to the English public to say, that the additions were originally written for the American edition of this book, published by Messrs. Estes & Lauriat, of Boston, Ma.s.s. To free them from the American character which they very naturally bear, would have necessitated the resetting of a great part of the work, and a consequent increase in its cost. It has been deemed advisable, therefore, to leave the whole of the text in its original condition, more especially as the changes are such that they can easily be supplied by the reader, and do not in the least affect the value of the information conveyed.

INTRODUCTORY CHAPTER.

THE TECHNICAL ELEMENTS OF ETCHING.

As explained in the Preface, this chapter has been added to enable the beginner to master the most necessary technical elements of etching, without complicating his first attempts by artistic considerations. Let him learn how to use his ground, his points, and his acid, before he endeavors to employ these requisites in the production of a work of art.

All the materials and tools necessary for making the experiment described below can be bought at the following places:[A]--

NEW YORK: Henry Leidel, Artist's Materials, 341 Fourth Avenue.

PHILADELPHIA: Janentzky & Co., Artist's Materials, 1125 Chestnut Street.

BOSTON: J. H. Daniels, Printer, 223 Washington Street.

But any one living within reach of a druggist, a paint-shop, and a hardware-store can do just as well with the exercise of a little patience and a very little ingenuity. For the benefit of such persons all the necessary directions will be given for making what it may be impossible to buy.

[A] In London, Mr. Hamerton recommends Mr. Charles Roberson, 99 Long Acre.

1. =Definition of Etching.=--To be able to get an impression on paper from a metal plate in a copper-plate printing-press, it is necessary to sink the lines of the design below the surface of the plate, so that each line is represented by a furrow. The plate is then inked all over, care being taken to fill each furrow, and finally the ink is cautiously wiped away from the surface, while the furrows are left charged with it.

A piece of moist paper pressed against a plate so prepared, will take the ink up out of the furrows. The result is an impression. In _engraving proper_ these furrows are cut into the plate by mechanical means; in _etching_ chemical means are used for the same purpose. If nitric acid is brought into contact with copper, the acid corrodes the metal and finally eats it up altogether; if it is brought into contact with wax or resinous substances, no action ensues. Hence, if we cover a copper plate with a ground or varnish composed of wax and resinous substances, and then draw lines upon this ground with a steel or iron style or point, so that each stroke of the point lays bare the copper, we shall have a drawing in lines of copper (which are affected by nitric acid) on a ground of varnish (which is not thus affected). If now we expose the plate to the action of nitric acid for a certain length of time, we shall find, upon the removal of the ground by means of benzine, that the lines have been _bitten into_ the plate, so that each line forms a furrow capable of taking up the ink. The depth and the breadth of the lines depends upon the thickness of the points used, and upon the length of time allowed for biting; or, in other words, by varying the size of the points and the time of exposure the lines may also be made to vary. This is the whole of the _science_ of etching in a nutsh.e.l.l.

2. =Requisites.=--The following tools and materials are the only ones which are absolutely necessary for a first experiment:--

1. A COPPER PLATE on which to execute your etching. Do not waste your money on a large plate. A visiting-card plate is sufficiently large. If you happen to have an engraved plate of that kind, you can use the back of it. If you have none, get one at a card-engraver's. The price ought not to be over fifteen cents. If you do not live in any of the large cities named above, or cannot find a card-engraver, send fifteen cents in stamps to Mr. Geo. B. Sharp, 45 Gold St., New York, N. Y., who will forward a plate to you by mail. Be very particular in giving your full and correct _post-office_ address. These plates only need cleaning to fit them for use.

2. BENZINE, used for cleaning the plate, sold by grocers or druggists at about five cents a pint for common quality.

3. WHITING or SPANISH WHITE, also for cleaning the plate. A very small quant.i.ty will do.

4. CLEAN COTTON RAGS.--Some pieces of soft old shirting are just the thing.

5. ETCHING-GROUND, with which to protect the plate against the action of the acid. This ground is sold in b.a.l.l.s about the size of a walnut. If you do not live in a city where you can buy the ground, you may as well make it yourself. Here is a recipe for a very cheap and at the same time very good ground. It is the ground used by Mr. Peter Moran, one of the most experienced of our American etchers. Buy at a drug-shop (not an apothecary's) or painter's supply-store:--

Two ounces best natural asphaltum (also called Egyptian asphaltum), worth about ten cents.

One and a half ounces best white virgin wax, worth about six cents.

One ounce Burgundy pitch, worth say five cents.

Break the wax into small pieces, and reduce the Burgundy pitch to fine powder in a mortar, or have it powdered at the drug-shop. Take a clean earthenware pot glazed on the inside, with a handle to it (in Boston you can buy one for fifteen cents at G. A. Miller & Co.'s, 101 Shawmut Avenue), and in this pot melt your asphaltum over a slow fire, taking very good care not to let it boil over, or otherwise you might possibly set the house afire. When the asphaltum has melted add the wax gradually, stirring all the while with a clean gla.s.s or metal rod. Then add the Burgundy pitch in the same way. Keep stirring the fluid ma.s.s, and let it boil up two or three times, always taking care to prevent boiling over! Then pour the whole into a pan full of tepid water, and while it is still soft and pliant, form into b.a.l.l.s of the required size, working all the while under the water. If you touch the ma.s.s while it is still too hot, you may possibly burn your fingers, but a true enthusiast does not care for such small things. You will thus get about eight or nine b.a.l.l.s of very good ground at an outlay of about thirty-six cents in cash, and some little time. Nearly all recipes order the wax to be melted first, but as the asphaltum requires a greater heat to reduce it to a fluid condition, it is best to commence with the least tractable substance. For use, wrap a ball of the ground in a piece of fine and close silk (taffeta), and tie this together with a string.

6. MEANS OF HEATING THE PLATE.--Any source of heat emitting no smoke will do, such as a kitchen stove, a spirit lamp, or a small quant.i.ty of alcohol poured on a plate and ignited (when the time arrives).

7. A HAND VICE with a wooden handle, for holding the plate while heating it; price about seventy-five cents at the hardware-stores. But a small monkey-wrench will do as well, and for this experiment you can even get along with a pair of pincers.

8. A DABBER for laying the ground on the plate. Cut a piece of stout card-board, two or three inches in diameter; on this lay a bunch of horse-hair, freed from all dust, and over this again some cotton wool.

Cover the whole with one or two pieces of clean taffeta (a clean piece of an old silk dress will do), draw them together tightly over the card-board, and tie with a string. When finished the thing will look something like a lady's toilet-ball. The horse-hair is not absolutely necessary, and may be omitted.

9. MEANS OF SMOKING THE GROUND.--The ground when laid on the plate with the dabber, is quite transparent and allows the glitter of the metal to shine through. To obtain a better working surface the ground is blackened by smoking it. For this purpose the thin wax-tapers known to Germans as "Wachsstock," generally sold at German toy-stores, are the best. They come in b.a.l.l.s. Cut the tapers into lengths, and twist six of them together. In default of these tapers, roll a piece of cotton cloth into a roll about as thick and as long as your middle finger, and soak one end of it in common lamp or sperm oil.

10. STOPPING-OUT VARNISH, used for protecting the back and the edges of the plate, and for "stopping out," of which more hereafter. If you cannot buy it you can make it by dissolving an ounce of asphaltum, the same as that used for the ground, in about an ounce and a half of spirits of turpentine. Add the asphaltum to the turpentine little by little; shake the bottle containing the mixture frequently; keep it in the sun or a moderately warm place. The operation will require several days. The solution when finished should be of the consistency of thick honey.

11. CAMEL'S-HAIR BRUSHES, two or three of different sizes, for laying on the stopping-out varnish, and for other purposes.

12. ETCHING POINTS OR NEEDLES, for scratching the lines into the ground.

Rat-tail files of good quality, costing about twenty cents each at the hardware-stores, are excellent for the purpose. Two are all you need for your experiment, and even one will be sufficient. Still cheaper points can be made of sewing, knitting, or any other kind of needles, mounted in sticks of wood like the lead of a lead-pencil. Use glue or sealing-wax to fasten them in the wood.

13. AN OIL-STONE for grinding the points.

14. AN ETCHING-TRAY to hold the acid during the operation of biting.

Trays are made of gla.s.s, porcelain, or india-rubber, and can generally be had at the photographer's supply-stores. A small india-rubber tray, large enough for your experiment, measuring four by five inches, costs fifty-five cents. But you can make an excellent tray yourself of paper.

Make a box, of the required size and about one and a half inches high, of pasteboard, covered over by several layers of strong paper, well glued on. If you can manage to make a lip or spout in one of the corners, so much the better. After the glue has well dried pour stopping-out varnish into the box, and float it all over the bottom and the sides; pour the residue of the varnish back into your bottle, and allow the varnish in the box to dry; then paint the outside of the box with the same varnish. Repeat this process three or four times. Such a tray, with an occasional fresh coating of varnish, will last forever.

For your experiment, however, any small porcelain (_not_ earthenware) or gla.s.s dish will do, if it is only large enough to hold your plate, and allow the acid to stand over it to the height of about half an inch.

15. A PLATE-LIFTER, to lift your plate into and out of the bath without soiling your fingers. It consists of two pieces of string, each say twelve to fifteen inches long, tied to two cross-pieces of wood, each about six inches long, thus [Ill.u.s.tration]. It is well to keep the fingers out of the acid, as it causes yellow spots on the skin, which remain till they wear off.

16. NITRIC ACID for biting in the lines. Any nitric acid sold by druggists will do, but the best is the so-called chemically pure nitric acid made by Messrs. Powers & Weightman, of Philadelphia. It comes put up in gla.s.s-stoppered bottles, the smallest of which hold one pound, and sell for about sixty cents.

17. WATER for mixing with the acid and for washing the plate.
