This paper, made by transferring, pasting, or painting a coating of metal on ordinary paper, retains a comparatively dull and dead appearance even after glazing or polishing with the burnisher or agate. Galvanized or electroplated metal paper, on the other hand, in which the metal has penetrated into the most minute pores of the paper, possesses an extraordinarily brilliant polish, fully equal to that of a piece of compact polished metal. It is much more extensively used than the kind first mentioned.

The following solutions are recommended for making "galvanized" metal paper:

I

For silver paper: Twenty parts argento-cyanide of potassium; 13 parts cyanide of potassium; 980 parts water.

II

For gold paper: Four parts aurocyanide of potassium; 9 parts cyanide of potassium; 900 parts water.

Moth Paper

Naphthalene........ 4 ounces

Paraffine wax....... 8 ounces

Melt together and while warm paint unsized paper and pack away with the goods.

Lead Paper

Lay rough drawing paper (such as contains starch) on an 8 per cent potassium iodide solution. After a moment take it out and dry. Next, in a dark room, float the paper face downward on an 8 per cent lead nitrate solution. This sensitizes the paper. Dry again. The paper is now ready for printing. This process should be carried on till all the detail is out in a grayish color. Then develop in a 10 per cent ammonium chloride solution. The tones obtained are of a fine blue black.

Aluminum Paper

Aluminum paper is not leaf aluminum, but real paper glazed with aluminum powder. It is said to keep food materials fresh. The basic material is artificial parchment, coated with a solution of rosin in alcohol or ether. After drying, the paper is. warmed until the rosin has again softened to a slight degree. The aluminum powder is dusted on and the paper then placed under heavy pressure to force the powder firmly into it. The metallic coating thus formed is not affected by air or greasy substances.
