All Firing Schedules

C6PLST Firing Schedule

Plainsman Cone 6 Electric Standard

Typically we use an exhaust fan for a couple of hours at start of firing. Kilns are fairly empty, mainly test bars. Pieces in the kiln have not been bisque fired and are generally not glazed.

If the kiln is full, we lengthen the first step hold time to drive out all residual water from body and glaze.

We always include a self supporting cone. If the cone does not fall the correct amount, we adjust the firing schedule for next time.

Step	°C	°F	Hold	Time
1	55°C/hr to 121C	100°F/hr to 250F	60min	2:45
2	1944°C/hr to 1148C	3500°F/hr to 2100F	0	3:16
3	60°C/hr to 1204C	108°F/hr to 2200F	10min	4:22
