muriatic acids, (glass vessels only are to be used in this work,) when it is all cut dissolve 1/2 an ounce of sulphate of potash in one pint of pure rain water, and mix the gold solution, stirring well; then let stand and the gold will be thrown down; then pour off the acid fluid, and wash the gold in two or three waters, or until no acid is tasted by touching the tongue to the gold. Now dissolve one ounce of cyanuret of potassium in one pint of pure rain water, to which add the gold, and it is ready to use. Clear the article to be plated from all dirt and grease with whiting and a good brush; if there are cracks it may be necessary to put the article in a solution of caustic potash. At all events every particle of dirt and grease must be removed; then suspend the article in the cyanuret of gold solution, with a small strip of zinc cut about the width of a common knitting needle, hooking the top over a stick which will reach across the top of the vessel or bottle holding the solution. If the zinc is too large the deposit will be made so fast that it will scale off. The slower the plating goes on the better, and this is arranged by the size if the zinc used. When not using the plating fluid keep it well corked and it is always ready to use, bearing in mind that it is poison as arsenic, and must be put high out of the way of children, and labelled poison, although you need have no fear using it; yet accidents might arise if its nature were not known.
9. ELECTRO SILVERING--USUAL METHOD
This is done every way the same as gold plating (using coin) except that rock salt is used instead of the cyanuret of potassium to hold the silver in solution for use, and when it is of the proper strength of salt it has a thick curdy appearance, or you can add salt until the silver will deposit on the article to be plated, which is all that is required. No hesitation need be felt in trying these receipts, as they are obtained from a genuine source, and are in every day use.
10. GOLD PLATING FLUID
Warm six ounces of pure rain water, and dissolve in it 2 ounces of cyanide of potassium, then add a 1/4 ounce oxide of gold; the solution will at first be yellowish, but will soon subside to white; then half fill a bottle with whiting, fill it up with this solution and shake it well; you may now take a piece of old cotton, wet it with the solution, rub it well over brass, copper, &c., and it is nicely washed with gold.
11. SILVER PLATING FLUID
Dissolve one ounce of nitrate of silver, in crystal, in 12 ounces of soft water; then dissolve in the water two ounces of cyanuret of potash; shake the whole together and let it stand until it becomes clear. Have ready some 1/2 ounce vials, and fill them half full of whiting, then fill up the bottles and it is ready for use. The whiting does not increase the coating powder--it only helps to clear the articles and save the silver fluid by half filling the bottles. The above quantity of materials will cost about $1.62c., so that the fluid will be about 3 cents a bottle. It is used in the same way as the gold plating fluid.
12. QUICKSILVER PLATING FLUID
Take of quicksilver one ounce, one ounce nitric acid, one ten cent piece, rain water 1/2 pint to a pint, put the three first articles into a tumbler together; let them stand until dissolved, occasionally stirring, then add the water, and it is ready for use. This is used in the same way as the silver and gold plating fluid.
13. TO GILD STEEL
Pour some of the ethereal solution of gold into a wine-glass, and dip into it the blade of a new penknife, lancet, razor, &c., withdraw the instrument and allow the ether to evaporate, the blade will then be found to be covered with a beautiful coat of gold; the blade may be moistened with a clean rag or a small piece of very dry sponge dipped into the ether, and the same effect will be produced.
14. TO GILD COPPER, BRASS, &c.--BY AN AMALGAM
The gilding of these inferior metals and alloys of them is effected by the assistance of mercury with which the gold is amalgamated. The mercury is evaporated while the gold is fixed by the application of heat, the whole is then burnished of left mat in the whole or in part, according as required.
