Granite.—There are several varieties of granite, the principal being termed "grey" and "red" respectively. To mix the former ground, add a little black and Prussian blue with just a touch of Indian red to white. The grounds for red granites can be produced by mixing Venetian red and white.
Rouge Royal.—A mixture of Indian red, Venetian red and vegetable black, with a little white, will make the correct colour for the ground of this beautiful marble. It is very necessary that the ground be quite "solid," and to produce this, two, or even three, coats may be necessary.
Egyptian Green.—The ground should be a dead black.
Verd Antique.—The same as above.
Devonshire Marble.—Venetian red and ochre with a little white to produce a light terra-cotta ground.
Black and Gold.—A dead black ground should be used.
Dove.—In this case a white ground without gloss may be employed, but a grey is better, such as that produced by tinting white with Prussian blue, a little black and a very little Indian red.
Grey.—The same as "dove."
St. Anne's—A dead black ground should be used.
