THE DARK-RED MARBLE.
The marbled edges are always named from the body-color, as the latter always occupies the largest space on the edge. For dark-red marble the following colors are used: black, light pink (10 parts white, 1 part safflower-carmine), light-grey (10 parts white, 1 part black), gall-water and, finally, the ground color.
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.
