Hardwood Charcoal

タイトルまたは説明

Hardwood Charcoal.
Charcoal is a lightweight, 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
Today, the process of making lump charcoal typically begins by stacking wood logs in underground pits and covering them with sheet metal and dirt. The logs are lit at one end of the pile and the wood smolders for a few days. During this time, the oxygen-starved fire burns off water, sap and other volatile substances in the wood. What's left is almost pure carbon, also known as char or lump charcoal
