Description

An impure black carbon pigment originally prepared from charred ivory or horns. Ivory black is a fine-grain, dense black pigment. Current formulations of ivory black usually contain a fine grade of bone black with some Prussian blue. Bone black contains about 10% carbon along with 84% calcium hydroxyapatite with smaller amounts of magnesium phosphate and calcium carbonate. Ivory black is a stable blue-black pigment that is denser than carbon black and has a good working quality for oil paints and watercolors.
