Wood Charcoal

Wood

Wood is a natural, lignocellulosic material derived primarily from the secondary xylem of trees and other woody plants, where it provides mechanical support and in the functional sapwood, conducts water and dissolved minerals. Being a natural material, it is characterized as an organic material – a natural composite of cellulosic fibers that are strong in tension and embedded in a matrix of lignin and hemicelluloses that resists compression.

Charcoal

Charcoal is a lightweight black residue made of carbon that is produced by strongly heating wood 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 kiln, 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 briquettes used for outdoor cooking may contain many other additives, e.g. coal.
