*Charcoal* is a light black residue consisting of carbon, and any remaining
ash, obtained by removing water and other volatile constituents from animal
and vegetation substances. Charcoal is usually produced by slow pyrolysis,
the heating of wood or other substances in the absence of oxygen (see
pyrolysis, char and biochar). It is usually an impure form of carbon as it
contains ash; however, sugar *charcoal* is among the purest forms of carbon
readily available, particularly if it is not made by heating but by a
dehydration reaction with sulfuric acid to minimise introducing new
impurities, as impurities can be removed from the sugar in advance. The
resulting soft, brittle, lightweight, black, porous material resembles
coal.^[1]
