Charcoalis
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.
