CHAPTER VIII.

CHEMICAL DEPARTMENT.

HOW TO IMITATE GOLD.—Take the following metals and melt them in a covered crucible; sixteen ounces Virgin Platina, twenty-four ounces pure copper.

SILVER.—Forty ounces Nickel, twenty ounces Copper, thirty ounces Block Tin.

ARTIFICIAL GOLD.—Sixteen parts of Virgin Platina and seven parts Copper and one of Zinc. Put these in a crucible with powdered charcoal, and melt them together till the whole forms a mass, and are thoroughly incorporated together. This also makes a gold of extraordinary beauty and value. It is not possible by any tests that chemists know of to distinguish it from pure virgin gold. All I ask of men is to use it for good and lawful purposes, for the knowledge that I here give you will bring you a rich and permanent reward without using it for unlawful purposes.

MANHEIM, OR JEWELER'S GOLD.—Three parts of Copper, one part of Zinc, and one part of Block Tin. If these are pure and melted in a covered crucible containing charcoal, the resemblance will be so good the best judges cannot tell it from pure gold without analyzing it.

BEST PINCHBACK GOLD.—Five ounces of pure Copper and one ounce of Zinc. This makes gold so good in appearance that a great deal of deception by its use in the way of watches and jewelry has been successfully practiced for several hundred years back.

SILVER FLUID.—For silvering brass and copper articles of every description.—Take an ounce of precipitated Silver to half an ounce of Cyanate of Potash and quarter of an ounce of Hyper Sulphate of Soda. Put all into a quart of water, add a little whitening and shake before using. Apply with a soft rag. This knowledge alone is worth one hundred dollars.
