The ground is composed of Venetian red, red lead, and a small quantity of chrome yellow, mixed with oil and turpentine in equal parts; but additional brilliancy may be given the color by vermilion or lake, instead of Venetian red. While the ground is wet, dab on spots of white, using either a piece of sponge or a tool, and soften with a badger, subsequently repeating the white touches in parts, giving them increased brilliancy. Spots of blue, brown, yellow, etc. may, in the same manner, be added. When nearly dry, veins and threads may be put in with a camel's-hair pencil.

The name of the stone is derived from its granular formation. There are many kinds of granite used in the arts. Among these are the gray, red, green, violet, rose colored, etc. Those best known for architectural purposes are the gray Aberdeen granite and the reddish-colored Peterhead granite.
For gray granite, the ground is a gray made by mixing black and white; over this, spots are splashed with black and white, used separately, the work being carried out as set forth under the heading of porphyry. For the various shades of red granite, the ground is composed of Venetian red and white, the spots being black, white, and vermilion. In the same way, any of the other kinds may be reproduced.
