Charcoal is normally obtained from the burning of wood, peat, bones, cellulose, or other carbonaceous substances with little or insufficient air. It is an amorphous carbon in the form of highly porous microcrystalline graphite. When charcoal is used as an additive to clay, it can help save energy in brick production.
How is charcoal made naturally?
'Natural' charcoal is produced when the raw material is carbonised at a 500 – 5500C over a period of days. At this temperature vital nutrients in the wood are not driven off / carbonised. The charcoal produced is in chunks and can then be rendered into smaller pieces by crushing.
How is charcoal wood formed?
