john commented on the word bone char
Animal byproduct, formerly used in the production of sugar.
"Bone char, also known as bone black or animal charcoal, is a granular black material produced by calcinating animal bones: the bones are heated to high temperatures in the absence of air to drive off volatile substances. It consists mainly of calcium phosphate and a small amount of carbon. Bone char has a very high surface area and a high absorptive capacity for lead, mercury, and arsenic."
