Kachi Mangrove Charcoal or Lump Charcoal Or Charwood
Mangrove Charcoal, sometimes called charwood or natural charcoal, is made from pieces of wood that have been burned down into charcoal using the same oxygen-controlled environments described above for briquettes. However, at the end of the process, the charcoal chunks are bagged and sold as-is. There are no "other ingredients" in Mangrove Charcoal.
