SILVERING (Cycl.)~- This is a fpecies of gilding, and may be done thus : take as much aqua fortis as you think there is occafion for, put it into a glafs, which fet in warm afh.es ; then put in your quantity of filver, after having beaten it very thin, and cut it into little flireads. When the filver is dif- folved, take it off the afties; and, mixing that liquid with as much white tartar as will make it like parte ; rub with this mixture the metal you want to filver. Copper, brafs, or any other metal may be thus made to appear like filver itfelf.
Copper, brafs, fleel, or iron may be filmred, fo as not to come off, unlefs made red-hot, in the following manner. Take urine which is made in the morning, cover it, and let it ftand a whole month, and it will ferment; put it after- wards into an earthen pot, and let it boil ; fkirn it, and when the third part is evaporated, take to two pints of urine one ounce of tartar, and one ounce of galiz-ftone ; mix them all together, and let them boil once up. When you would fil- ver any metal, rub it well with brick-duft on a wet woollen rag, till it is clean and fine, then put it twenty-four hours in the prepared urine ; afterwards dry it, and where you defign to filver y rub it over with quick-filver, which muft be laid on thin with an iron fpatula that has alfo lain two hours in urine. The quick-filver thus laid on, muft be then rubbed on with a foft woollen rag, and it will make a tine filver- ing.
Brafs may befilvered, by boiling it with filings of good pew- ter and white tartar, in equal quantities. There are feveral other methods of filvering, for which fee Smith's Laboratory, p. 37. feq.
