Ivory Black is named so because the pigment used in its creation was derived from the charred bones of dead animals, a practice accredited to the ancient Romans. The pigment from the bones was further refined and added to oil where it was used as a primitive form of oil paint.
There were originally two forms of black paint, one a more basic type that was made from the bones of ordinary animals, and another higher grade that was made from ivory, resulting in a purer denser colour. Naturally, ivory is no longer used in the creation of pigment of this paint, but the name and the reference remain.
