The latter is composed of 2 parts carmine-lake, 1 part black and 3 parts sprinkling-water.
THE PLAIN-GRAY MARBLE.
This kind of marbling is the most profitable of the veined marbles because it can be produced very rapidly.
For this purpose prepare the black color with gall in such a way, that a drop will spread out on the size to a spot of about 5-1/2 inches in diameter, then add an equal quantity of sprinkling water, dip a large broom-corn whisk or a bristle-brush into the color and throw it by beating on a board upon the size which has been cleaned off by a strip of paper. The color appears on the size a gray color with white veins, from which the edge can be taken.
THE BLUE MARBLE.
To produce this use the following colors; black, orange or citron yellow, Indian red with a little black and Oriental blue, finally adding gall water and the body color. This ground color consists of 1 part Indigo and 1 part sprinkling water.
THE BROWN MARBLE.
This marble is one of the most common, but if the colors are well selected as given in the following paragraph it will give a fine effect.
Black first, Havana brown second, chamois third, gall water, and, as ground color, humin-brown with a little carmine lake and one part sprinkling water.
