In a perfect world, charcoal would be pure carbon. In practice it contains some uncharred cellulose and wood ash. Many sources approximate charcoal with the formula C7H4O Charcoal fires with forced air can attain higher temperatures than wood fires because less energy is given over to the vaporization of water, which is produced when the cellulose in wood is burned.
