I found this formula, how to silvering surface of brass:
1.You have to get silver. The best to use for silvering is AgNa3. This is the chemical used by illnesses of skin and eyes and You should get it in Your pharmacy. If not You can use everything, what is made from silver ”“ broken spoon, old coins etc. The problem is, most things like these are made not from pure silver, but from alloy of silver, copper, nickel and tin in most cases. Pure silver is too soft.
2.Drop Your silver in glass with 10% solution of HNO3 and put the glass in hot water to warm it. DO IT OUTDOOR!!! IT WILL BE TOXIC !! :shocked2:
3.I the second glass put a little salt from your kitchen in water and pour it into first glass. Slowly and still string. You will see the white deposit falling on the bottom. It is AgCl, what You exactly will need to work. Pour more water with salt. If the white deposit falls no more stop it ”“ You have now all silver from the solution on the bottom of glass.
4.Now when all deposit is fallen on the bottom, carefully pour out rest of the solution from glass. Keep the fur on the bottom!
5.Pour pure water into glass with AgCl on the bottom and mix it; and when the deposit will be fallen again, pour the water out carefully again. Do it 8-10 times to have only solution AgCl + pure water in glass, without rest of another metals (copper, nickel, tin from the thing, that You dropped in HNO3 before). Now pour the water out last time, but not all and put your AgCl with a little water in very dark glass. It must be protected from light !!
[url] 6.In[/url] dark room get 10 grams AgCl, 8 grams salt and 8 grams potassium bitartrate. Rub it all together to pulp in some ceramic or plastic. Use not any metal thing to do it ! Use wooden or plastic stick only.
7.Apply this mixture rubbing in surface of brass with piece of flannel or cotton.
8.Polish silvered surface.
