Is Boneblack Vegetarian?

Boneblack is a form of charcoal derived from animal bones, primarily used in industrial applications. It is produced by heating bones to high temperatures in an oxygen-deprived environment, resulting in a black, porous material. Historically, boneblack has been used as a filtration medium in the sugar refining process to decolorize and purify the product, although its use has decreased with the development of alternative refining methods. In addition to sugar production, boneblack has applications in water filtration and as a pigment in some art materials.
