Ivory black at 100x (visible light left; UV light right)

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.
