Rublev Colours Pigment Bone Black - 4 oz

Although sometimes compared to ivory black, bone black is distinct in its composition and color. Unlike ivory black, traditionally made from charred ivory or animal horns, bone black is derived exclusively from animal bones, offering a unique depth and richness for artistic applications. This pigment is perfect for those seeking a historical and natural black colour in their art.

Rublev Colours Bone Black pigment is naturally derived from charring ground animal bones, namely bovine and porcine. We label it as an inorganic pigment to classify it in either of two categories: inorganic or organic pigments because the resulting product from bone char mainly consists of hydroxyapatite, calcium carbonate, and carbon, all of which are considered to be inorganic substances. Hydroxyapatite, also known as bone mineral, is a naturally occurring mineral form of calcium apatite. Although naturally derived, it is a synthetic substance since it has been altered by human intervention; namely, it was charred in a kiln. In reality, bone black still contains organic substances that are not entirely modified or vaporized by heating in a kiln.

Warning: Bone black is not considered hazardous, but care should be taken in handling the dry powder pigment to avoid inhaling the dust.
