Charcoal

タイトルまたは説明

Charcoal is a lightweight black carbon residue produced by removing water and other volatile constituents from animal and plant materials. Charcoal is usually produced by slow pyrolysis — the heating of wood or other organic materials in the absence of oxygen. This process is called charcoal burning. The finished charcoal consists largely of carbon.
The advantage of using charcoal instead of just burning wood is the absence of water and other components. This allows charcoal to burn at higher temperatures, and give off very little smoke (regular wood gives off a good amount of steam, organic volatiles, and unburnt carbon particles — soot — in its smoke).
