Descripción
Material created by charring animal bones, black in color. Bone black is composed of about 10% carbon and 84% calcium hydroxyapatite along with smaller amounts of magnesium phosphate and calcium carbonate. It is used primarily as a pigment and as a decolorizing and deodorizing agent. As a stable blue-black pigment, it is dense and has a good working quality for oil paints and watercolors. It is also used in engraving inks and as a decolorizing agent for refining sugars and syrups.
