White Charcoal and Black Charcoal

Description
There are two different ways to produce charcoal, and you can get White Charcoal and Black Charcoal depending on which you use. If the burnt wood is cooled by covering it with sand, you get white charcoal, and if it's cooled without covering it with sand, you get black charcoal.
