n. The product of heating carbonaceous materials, such as wood, at 900-1100F in a low-oxygen environment; the resulting material contains 80 to 98 percent carbon.

When wood is heated at temperatures in the range of 900-1100F in a low-oxygen environment, it loses more than half of its volume and weight due to the loss of moisture and volatiles.  The resulting fuel contains a higher amount of heat per unit volume than the parent wood.  Charcoal is a product commonly produced in third world countries as a major cooking and heating fuel.
