Hardwood lump charcoal is made from hardwood scrap from various sources. Branches, twigs, blocks, trim, and other scraps are carbonized. The result is lumps that are irregular in size. Often they are carbonized to different degrees because there are so many different size lumps. Lump leaves little ash since there are no binders as in briquettes.
