Charcoal is useful for reducing metallic oxides, because it can chemically combine with the oxygen in the metal oxide. This produces a gas (carbon dioxide), which escapes. This has been the method by which many elements were isolated. The same process, with another form of carbon (called "coke"), is used at an industrial level, for example, in making [[steel]].
