charcoal

Product Description

Charcoal, a form of amorphous carbon, is produced when
wood, peat, bones, cellulose, or other carbonaceous
substances are heated with little or no air present. A
highly porous residue of microcrystalline graphite
remains.
Charcoal is a fuel and was used in blast furnaces until the
advent of coke. Today most charcoal is used for recreational,
restaurant, and home cooking in the form of
charcoal briquettes. A small amount of charcoal is used
in certain metallurgical processes and as a filter to
remove organic compounds such as chlorine, gasoline,
pesticides, and other toxic chemicals from water and air.
