Plainsman Typical Cone 04

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.

Step	°C	°F	Hold	Time
1	100°C/hr to 100C	180°F/hr to 212F	60min	2:02
2	150°C/hr to 960C	270°F/hr to 1760F	0	7:46
3	100°C/hr to 1060C	180°F/hr to 1940F	5min	8:51
4	Freefall°C/hr to 30C	0°F/hr to 86F		8:51

Start temperature assumed: 25°C or 75°F
