Re: Elkington & Co. - Information and Advertisements
In preparing articles for plating, they must be completely freed from grease by washing in an alkaline ley, and dipped into very diluted nitric acid to remove any traces of oxide. The object is then suspended in the decomposing trough and connected with the negative pole of the battery, the positive pole being connexion with a sheet of silver in the solution. Silver is immediately deposited, and the plating process proceeds as long as the object continues immersed. An ounce and a half of silver to one square foot of surface gives an excellent plating.
The articles when taken out of the solution are white, the silver being afterwards polished on the parts required to be bright. A bright deposit may, however, be made by adding a little sulphuret of carbon to the solution. When a thin coating of silver is deposited on a bright surface, the silver is also bright ; and in order to obtain a coating of dead silver on a medal, it should have a thin film of copper deposited over its surface before it is immersed in the silver solution, by which means the silver, even when very thin, will be white. In operating on a large scale, the decomposing trough is upwards of two yards long, one yard deep, and one yard wide, and contains about 250 gallons of the solution. At Messrs. Elkington's establishment at Birmingham, several of these troughs are in continual use. The silver plates in a single trough expose a surface of nearly thirty square feet, and the articles to be plated are suspended from metal rods that are connected with the positive pole of the battery. The voltaic batteries used by Messrs. Elkington generate large quantities of electricity of low intensity. When we inspected their manufactory, the deposition of each trough was effected by plates the zincs of which were three feet long by eighteen inches wide.

PRACTICE OF ELECTRO-METALLURGY
Mr. Napier, superintendent of the scientific department of Messrs. Elkington's Works, has explained at the Royal Institution, some curious points in the practice of electro-plating,—a new application of electricity in reducing metals from ores which, like that of copper, can be fused by a flux.
1. As to Electro-plating: —Mr. Napier commenced by noticing the known difference between solid and liquid conductors of electricity — i. e., that the latter are decomposed by the current which they convey ; on this property the principle of all the electro processes rests. The mode in which the copper is deposited from the liquid sulphate on a surface connected with the zinc terminal of the battery was then illustrated theoretically by a diagram, and practically by a large sheet of cloth covered by these means. The object of this fabric is to furnish a roofing for houses, lining and ornamenting rooms, and covering railroad carriages ; —not only waterproof, but also not liable to be set on fire by sparks falling on it. Mr. Napier here noticed the difficulty of maintaining that equable diffusion of the copper-salt through the solution which should insure the uniform deposit of the metal. This can only be effected by keeping either the liquid or the article in constant motion, or else by placing the latter horizontally at the bottom of the former—care being always taken to insure the solution being constantly saturated by suspending crystals of the salt in it. In plating goods with gold or silver, recourse is had to the cyanides of those metals. The preparation of the cyanide of potassium from the common yellow ferro-cyanide was described. This salt separates silver from the nitrate, and gold from the chloride, forming the required cyanide. An instantaneous gilding of several articles was effected before the audience. The subsequent process of brushing and burnishing, by which the soundness of the work is tested, were then exhibited.
2. As to the fabrication of solid silver articles: —On a model of metal, or plaster of Paris, or any other suitable material, is poured a compound of 12 parts of glue and 3 of treacle, melted together. This, when cooled, forms a perfectly flexible mould, from which any sculptured surface, even if there be much under-cutting on it, can be easily detached. Into a mould so prepared is poured a mixture of 3 parts tallow, 1 wax, and ½ resin. This dissolves at a low temperature ; and when liquid, and previously to being poured into the mould, it receives half an ounce of phosphorus, dissolved in sulphuret of carbon. This, diffused through the melted mass thus described, gives it the property of reducing silver from its nitrate. The new model, then, taken from the mould, is moistened with nitrate of silver, and becomes covered with a thin film, of that metal, on which copper is deposited by the battery-current. When this second mould is considered sufficiently thick, the fusible compound is melted away, the copper mould is protected at the back by non-conducting surface, generally a mixture of pitch and tar. Silver is then deposited within this mould, of any required solidity, from the solution of cyanide of silver and the battery-current ; and, finally, the copper mould is dissolved by the perchloride of iron, leaving the silver pure. By the same process, delicate organic textures are gilded. In all cases where it is desired to insure perfect metallic coating, the article, (after having been washed with the sulphuret of carbon and phosphorus,) is immersed first in a solution of nitrate of silver, and then of chloride of gold, both very dilute.
3. As to the reduction of copper, etc. from their ores by electricity : —Mr. Napier has proposed the following process for applying this discovery to practical purposes. He mixes the roasted ore with soda and lime, and places the whole on a bed of blacklead tiles in a reverberatory furnace ; these are connected with the zinc terminal of the battery, and the surface of the mass, when fused, is covered with an iron plate, which is put into connexion with the copper terminal. At the expiration of a period depending on the power of the battery, the complete extraction of the copper takes place, which is found collected at the bottom, amounting to, according to present experience, from 12 to 16 times the weight of the zinc dissolved in the battery-cell. Whether these results are dependent throughout on the direct electrolyzation of the fused mass, or if electrolyzation be the primary effect, deranging the constitution of the compounds, and which, in connexion with the intense heat, produces the results referred to, Mr. Napier cannot as yet say.

Re: Elkington & Co. - Information and Advertisements
Messrs. Elkington & Co. have despatched to the Paris Exhibition a shield which has just been completed, after more than two years of diligent labor, by M. Morel-Ladeuil, the artist by whom the “ Milton ” shield, now at South Kensington, was produced, and who is also well known by many other specimens of repousse'e work of the highest excellence. The “ Bunyan ” shield is the same size as the “ Milton,” and consists, like the latter, of five plates or medallions of beaten silver mounted in iron; but the shape of the plates is different from that of those in the Milton shield. The central plate represents the combat between Christian and Apollyon; and the time selected by the artist is when Christian is delivering his final blow, which secured to him the victory over his adversary. The faces of both the combatants are in the highest degree vigorous and expressive; and the accessories of the scene, the attendant fiends and angels, are introduced with great skill and judgment. At the feet of Christian is the helmet, which he lost early in the encounter, and he is repelling the last of Apollyon’s darts with the shield of faith, while his right hand swings back the sword of the spirit in a pose which is full of life and earnestness. Immediately beneath this medallion, in the iron, is a figure of John Bunyan, sleeping, and much refined upon the actual representations of the worthy cobbler. The two lower medallions exhibit the Valley of the Shadow of Death, thronged with shapes hideous and horrible, among which the narrow road is seen winding; while the upper medallions represent the road to the Celestial City, passing through the “glorious company of Seraphim and Cherubim, the Elders with their golden crowns, and the Virgins with their harps.” Beneath the silver bas-reliefs, and in the iron work, are escutcheons bearing devices emblematical of the three Christian virtues, faith, hope, and charity. The surfaces of iron between the medallions are further embellished with appropriate arabesques, here and there enriched by gold inlaying; but the general effect is somewhat more severe than that of the Milton shield, as befits the subject. The hammer work, taking it as a whole, is of extraordinary excellence, and the relief, in some parts, is wonderfully high and sharp, as, for example, in the wings of Apollyon and the sword of Christian.
