Description

Common charcoal is made from peat, coal, wood, coconut shell, or petroleum.
Sugar charcoal is obtained from the carbonization of sugar and is particularly pure. It is purified by boiling with acids to remove any mineral matter and is then burned for a long time in a current of chlorine in order to remove the last traces of hydrogen.
 Activated charcoal is similar to common charcoal but is made especially for medical use. To produce activated charcoal, its  heat common charcoal in the presence of a gas that causes the charcoal to develop many internal spaces or "pores." These pores help activated charcoal trap chemicals.
Lump charcoal is a traditional charcoal made directly from hardwood material. It usually produces far less ash than briquettes.
Pillow shaped briquettes are made by compressing charcoal, typically made from sawdust and other wood by-products
