Wool grease, 46 parts, by weight; fire clay, 30 parts, by weight; paraffine, 5 parts, by weight; Canova wax, 5 parts, by weight; cocoa-nut oil, 10 parts, by weight; oil of mirbane, 1 part, by weight. After mixing these different ingredients, which constitute a paste, this is molded in order to give a cylindrical form, and introduced into a case so that it can be used like a stick of cosmetic.
Oxalic acid, 1 part; caput mortuum, 15 parts (or, if white pomade is desired, tripoli, 12 parts); powdered pumice stone, best grade, 20 parts; palm oil, 60 parts; petroleum or oleine, 4 parts. Perfume with mirbane oil.
Oxalic acid........ 1 part
Peroxide of iron
(jewelers' rouge).. 15 parts
Rotten stone....... 20 parts
Palm oil........... 60 parts
Petrolatum........ 5 parts
Pulverize the acid and the rotten stone and mix thoroughly with the rouge. Sift to remove all grit, then make into a paste with the oil and petrolatum. A little nitro-benzol may be added to scent the mixture.
Oleine............ 40 parts
Ceresine........... 5 parts
Tripoli............ 40 parts
Light mineral oil
(0.870).......... 20 parts
Melt the oleine, ceresine, and mineral oil together, and stir in the tripoli; next, grind evenly in a paint mill.
Boil about 10 to 15 parts of caustic soda or 100 parts of soda in 1,000 parts of water, immerse the parts to be cleaned in this for some time, or, better, boil them with it. Then rinse and dry. For small shops this mode of cleaning is doubtless the best.
Put sulphuric acid 100 parts and potassium nitrate (saltpeter) 10 parts in a vessel of stoneware or porcelain, heated on the water bath. When the silver has left the copper, rinse the objects several times. This silver stripping bath may be used several times, if it is kept in a well-closed bottle. When it is saturated with silver, decant the liquid, boil it to dryness, then add the residue to the deposit, and melt in the crucible to obtain the metal.
Stripping silvered articles of the silvering may be accomplished by the following mixture: Sulphuric acid, 60° B., 3 parts; nitric acid, 40° B., 1 part; heat the mixture to about 166° F., and immerse the articles by means of a copper wire. In a few seconds the acid mixture will have done the work. A thorough rinsing off is, of course, necessary.
