To begin controlled cooling, allow the kiln to cool as fast as it can for the first 300Â° so the controlled portion of the firing is taking place about 300Â° lower than the cut-off temperature.
It also keeps fumes out of your kiln room by venting them outside. The exhaust fan automatically waits until the kiln turns on, then goes off when the firing is complete. When cooling, the fan turns back on at 1000F automatically and off at 140F for safe cooling to protect your pieces.
