What are bone black and coke examples of?

Bone black and coke are examples of carbonaceous materials. Bone black, also known as animal charcoal or bone char, is produced by the carbonization of animal bones and is primarily used as a pigment and in filtration processes. Coke, on the other hand, is a porous, carbon-rich material derived from the destructive distillation of coal and is used primarily as a fuel and reducing agent in metallurgical processes. Both materials play significant roles in various industrial applications due to their carbon content.
