I.—Blue.—Boil 106 parts of sand and 4 of Berlin blue with a small quantity of water, stirring constantly, and dry as soon as the sand is thoroughly colored.
II.—Black Sand.—Heat very fine quartz sand, previously freed from dust by sifting, and add to every 1/4 pound of it 6 to 8 spoonfuls of fat. Continue the heating as long as smoke or a flame is observed on stirring. The sand is finally washed and dried. This black sand will not rub off.
III.—Dark-Brown Sand.—Boil white sand in a decoction of brazil wood and dry it over a fire.
