No. 1. Flesh Color

Red lead, 1 oz.; red enamel (Venetian glass enamel, from alum and copperas calcined together): grind them to a fine powder, and work this up with alcohol upon a hard stone. When slightly baked, this produces a fine flesh color.

No. 2. Black Color

Take 14 ½ oz. of smithy scales of iron; mix them with 2 oz. of white glass; antimony 1 oz.; manganese, ½ oz.: pound and grind these ingredients together, with strong vinegar.

No. 3. Brown Color

White glass or enamel, 1 oz.; good manganese, ½ oz.: grind together.

No. 4. Bed, rose and Brown Colors are made from peroxide of iron, prepared by nitric acid. The flux consists of borax, sand and minium, in small quantities.

Red Color may likewise be obtained from 1 oz. of red chalk, pounded, mixed with 2 oz. of white, hard enamel, and a little peroxide of copper.

A Bed may also be composed of rust of iron, glass of antimony, yellow glass of lead, such as is used by potters (or litharge,) each in equal quantities; to which a little sulphuret of silver is added. This composition, well ground, produces a very fine red color on glass.

No. 5. Green

2 oz. of brass, calcined into an oxide; 2 oz.; of minium, and 8 oz. of white sand: reduce them to a fine powder, which is to be enclosed in a well-luted crucible, and heated strongly in an air-furnace for an hour. When the mixture is cold, grind it in a brass mortar. Green may, however, be advantageously produced, by a yellow on one side, and a blue on the other. Oxide of chrome has been also employed to stain glass green.

No. 6. A Fine Yellow Stain

Take fine silver, laminated thin, dissolve in nitric acid, dilute with abundance of water, and precipitate with solution of sea-salt; mix this chloride of silver in a dry powder, With three times its weight of pipe-clay, well burnt and pounded. The back of the glass pane is to be painted with this powder; for; when painted on the face, it is apt to run into the other colors.

A Pale Yellow can be made by mixing sulphuret of silver with glass of antimony and yellow ochre, previously calcined to a red-brown tint. Work all these powders together, and paint on the back of the glass. Or silver laminae melted with sulphur, and glass of antimony, thrown into cold water, and afterwards ground to powder, afford a yellow.

A Pale Yellow may he made with the powder resulting from bra . sulphur and glass of antimony, calcined together in a crucible till they cease to smoke, and then mixed with a little burnt ochre.

The Fine Yellow of M. Meraud is prepared from chloride of silver, oxide of zinc, and rust of iron. This mixture, simply ground, is applied on the glass.

Orange Color

Take 1 part of silver-powder, as precipitated from the nitrate of that metal, by plates of copper, and washed; mix with 1 part of red ochre, and 1 of yellow, by careful trituration; grind into a thin pap, with oil of turpentine or lavender; apply this with a brush, and burn in.
