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.
Divide the temperature the kiln cooled by the hours of cooling. That is the kilnâs natural cooling rate. To avoid error messages, program a slow cooling segment at a slower rate than your kilnâs natural cooling rate.
