Charcoal is carbon in its non-crystalline form. It is used for a variety of purposes, including fuel for fire and steel production.


  • Charcoal briquettes (commonly produced by partially burning wood) are used for outdoor barbecues. They burn slowly and without flames, providing steady heat for cooking picnic food
  • 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
  • Charcoal chemically bonds with a variety of substances. It is often "activated" (given a much greater surface area) and used for filtration. It can remove a wide variety of impurities from liquids and gasses. Carbon filters remove allergens and odors from air, chlorine and other contaminants from water, and even strip impurities from some forms of whiskey[1]
