Time and temperature
Time and temperature profile during the burn out period. Both time and temperature are important for proper burn out of the carbon. Some carbons require much higher temperatures that others. Oxidation should be completed below red heat (1400ºF). Carbon burns out from the surface first. As more oxygen penetrates the body, them more carbon is reacted to form the CO or CO2 gas and the burn out process continues. If there is sufficient time, temperature and oxygen, then complete burn out occurs. If these conditions do not exist, the resulting incomplete burn out is referred to as black coring (where the center of the piece has black or gray cast).
