Velvety top tone. It has a brownish undertone and makes brownish greys with white. It is moderately strong and is suitable for scumbling. This Ivory Black is opaque but not as opaque as Mars Black. It has a slightly warm, brown undertone. The name Ivory conveys a little about the history of the pigment, though it is no longer made from ivory. Sometimes, it's called Bone Black now since it comes from charred animal bone. Ivory Black is an all-purpose black and is a solid choice for mixing greys and creating coloured shades in our encaustic line.

Properties
Ivory Black is a cool, semi-transparent blue-black with a slight brownish undertone and average tinting strength. It mixes well with any colour and creates a range of dull greens mixed with yellow. It has good properties for use in oil, can be slow to dry in oil form, and should never be used in underpainting or frescoing. Ivory Black is denser than Lamp Black.
Permanence
Ivory Black is very lightfast and has good permanence, though it is considered the least permanent of the primary black pigments.
Toxicity
Ivory Black has no significant hazards.
History
Ivory Black is a carbon-based black first named Elephantium and was described in the 4th century BCE as being produced by heating ivory scraps in clay pots to reduce the ivory or bone to charcoal. The deviation in names is because the more expensive varieties of this pigment were made by burning ivory, and the less expensive ones by burning animal bones. In the 19th century, the name Ivory Black was finally permitted to be applied to Carbon Black pigments made from bone. Genuine Ivory Black is rare in modern times due to the protection of ivory, and the synthetic variety produced today was discovered in 1929. Bone Black is made as an industrial pigment.
