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.
A limit timer is a safety device which is set to turn the kiln off after an amount of time that you set. For example, if you expect your firing to last 8 hours, you may set the limit timer to 10 hours. At 10 hours the kiln will turn off.
