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  
Start temperature assumed: 25°C or 75°F
