Charcoal is just amorphous (non-crystalline) [[carbon]]. It is useful for reducing metallic oxides to the metal itself, because it can chemically combine with the oxygen in the metal oxide and turn into a gas (carbon dioxide), which escapes. This has been the method by which many elements were isolated, and is used at an industrial level, for example, in making [[steel]].
