A black, porous carbonaceous material. Charcoal is the carbon containing residue from burned wood (e.g., willow, maple, beech, linden or (tree) plum) or other organic containing materials such as bone, plants or animals. Charcoal contains 80 to 98% carbon with some ash and moisture. Charcoal has been used since ancient times as a drawing material and pigment (see black charcoal black). Charcoal is also sold commercially as a fuel, abrasive, sorbent, filter media, and decolorizer.
