Charcoal is a lightweight, black residue made by heating wood or other organic materials in the absence of oxygen. This process, called pyrolysis, removes water and volatile substances. The result is a carbon-rich material used for various purposes. Charcoal is porous and flammable, making it ideal as a fuel. It's been used since ancient times for cooking, heating, and smelting metals.
