Description

Charcoal is a lightweight black carbon residue produced by strongly heating wood(or other animals andplant materials) in minimal oxygen to remove all water and volatile constituents. In the traditional version of this pyrolysis process, called charcoal burning, often by forming a charcoal klin the heat is supplied by burning part of the starting material itself, with a limited supply of oxygen. The material can also be heated in a closed retort. Modern "charcoal" briquettesused for outdoor cooking may contain many other additives.
