Take a $2 50c. piece of gold, and put it into a mixture of 1 ounce of nitric and 4 ounces of 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.
