PLEASE NOTE: COPPRclay must be embedded in activated coconut carbon in sealed vessel during firing. Carbon and container are sold separately.
Firing Temp.: Ramp at full speed to 1,700°F–1,800°F (927°C–982°C) and hold for 3 hours (total firing time, including ramp-time, will be about 4 hours). Most firings perform well at 1,700°F; however, if you discover that your pieces are not sintering properly, try firing them at 1,800°F. If blistering occurs at 1,800°F, slightly decrease the firing temperature. If you plan to enamel the piece, please follow the recommended firing schedule listed in the included instructions.
