C04PLTP Firing Schedule
Plainsman Typical Cone 04
Four-step to 1940F with short hold and free-fall
Start temperature assumed: 25°C
||Rate to Temp °C
||100°C/hr to 100
||150°C/hr to 960
||100°C/hr to 1060
||Freefall°C/hr to 30
*Rates are expressed as "Celcius/Fahrenheit degrees", temperatures as "Degrees celcius/fahrenheit"
In the Plainsman lab we have standardized on a simple firing curve for test specimens that provides a soak for final drying and then proceeds to 100 degrees below the final temperature at 400 degrees per hour, then slows to 100 degrees per hour for the final stage. The cool is freefall. Of course, depending on the kiln used, the rate-of-rise might be slower, especially in the later stages.
