Bone char is primarily made from cattle and pig bones; however, to prevent the spread of Creutzfeldt–Jakob disease, the skull and spine are no longer used. [2] The bones are heated in a sealed vessel at up to 700 °C (1,292 °F); the oxygen concentration must be kept low while doing this, as it affects the quality of the product, particularly its adsorption capacity.
Terra preta is characterized by the presence of low-temperature charcoal residues in high concentrations; [2] of high quantities of tiny pottery shards; of organic matter such as plant residues, animal feces, fish and animal bones, and other material; and of nutrients such as nitrogen, phosphorus, calcium, zinc and manganese.

Bamboo charcoal. Bamboo charcoal is charcoal made from species of bamboo. It is typically made from the culms or refuse of mature bamboo plants and burned in ovens at temperatures ranging from 600 to 1,200 °C (1,100 to 2,200 °F). It is an especially porous charcoal, making it useful in the manufacture of activated carbon. [1]
