IVORY BLACK (Noir d'ivoire, Fr.; Kohle von Elfenbein, Germ.) is prepared from ivory dust, by calcination, in the very same way as is described under BONE BLACK.
The calcined matter, being ground and levigated on a porphyry slab, affords a beautiful velvety black, much used in copperplate printing. Ivory black may be prepared upon the small scale, by a well regulated ignition of the ivory dust in a covered crucible.
