a fine black pigment consisting of almostpure carbon collected as soot from thesmoke of burning oil, gas, etc.
BONE BLACK
.............................
Bone black is an impure black carbon pigment prepared from charring animal bones. Bone black is described in literature as being a deep blue-black to brown black color.

A fine particle size and high carbon content grade of bone black is sold commercially as ivory black.
