Temperature: 750 - 850

Description:Amorphous cargon burns from Texas Talc
Type:Decomposition

Notes

Texas talc contains carbon as CO2 in the dolomitic part of the ore (thus it is not detected as stand-alone talc in typical carbon burnoff testing). About 7% of the mass of the talc is expelled as gas. If you are single-firing glazed ware consider slowing the heating rate through this zone to allow for a more gentle gas evolution.
