charcoal Grade ACommercial charcoal is found in either lump, briquette, or extruded forms:

  • Lump charcoal is made directly from hardwood material and usually produces far less ash than briquettes.
  • Pillow shaped briquette are made by compressing charcoal, typically made from sawdust and other wood by-products, with a binder and other additives. The binder is usually starch. Some briquettes may also include brown coal (heat source), mineral carbon (heat source),borax,sodium nitrate (ignition aid),limestone (ash-whitening agent), sawdust (ignition aid), and other additives.
  • Extruded charcoal is made by extruding either raw ground wood or carbonized wood into logs without the use of a binder. The heat and pressure of the extruding process hold the charcoal together. If the extrusion is made from raw wood material, the  logs are then subsequently carbonized.
  • Japanese charcoal removes pyroligneous during the charcoal making. Therefore when burning, there are almost no stimulating smells or smoke. The charcoal of Japan is classified into three kinds.
    • White charcoal (Binchtan) is very hard and has a metallic sound.
    • Black charcoal
    • Ogatan is made from hardened sawdust. It is most often used in Izakaya or Yakiniku.
