The Direct Method. This is perhaps the easiest way to make charcoal. The direct method is to make a fire in a container, then add wood to it. Once it is burning, you cover the container loosely with a metal sheet to restrict the air. Watch as white smoke and steam from the wood comes out of the gaps around the cover.
