The following colors, are fusible by heat, and are all suitable for the decoration of china and glass. In the following collection of recipes certain terms are employed which may not be quite understood by persons who are not connected with either the glass or porcelain industries, such as "glost fire" and "run down," and in such cases reference must be made to the following definition's:

"Run down." Sufficient heat to melt into liquid.

"Glost fire." Ordinary glaze heat.

"Grind only." No calcmation required.

"Hard fire." Highest heat attainable.

"Frit." The ingredients partly composing a glaze, which require calcination.

"Stone." Always best Cornwall stone.

"Paris white." Superior quality of whiting.

"Parts." Always so many parts by weight, unless otherwise stated.

"D. L. Zinc." Particular brand not essential. Any good quality oxide of zinc will do.

Ruby and Maroon

Preparation of silver:

Nitric acid.......... 1 ounce

Water.............. 1 ounce

Dissolve the silver till saturated, then put a plate of copper in the solution to precipitate the silver in a metallic state. Wash well with water to remove the acetate of copper.

Flux for Above

Six dwts. white lead to 1 ounce prepared silver.

Tin Solution

Put the acid (aqua regia) in a bottle, add tin in small quantities until it becomes a dark-red color; let it stand about 4 days before use. When the acid becomes saturated it will turn red at the bottom of the bottle, then shake it up and add more tin; let it stand and it will become clear.

Aqua Regia

Nitric acid.......... 2 parts

Muriatic acid........ 1 part

Dissolve grain gold in the aqua regia so as to make a saturated solution. Take a basin and fill it 3 parts full of water; drop the solution of gold into it till it becomes an amber color. Into this solution of gold gradually drop the solution of tin, until the precipitate is complete. Wash the precipitate until the water becomes tasteless, then dry slowly and flux as follows:
