Stoneware glaze firings
- Pottery
- 20 Feb 2021
Below is a record of stoneware glaze firing schedules I have used with my electric kiln.
My kiln controller splits the firing into segements. They consist of
- a heating ramp (°C/h)
- a target temperature (°C)
- a soak period (h.mm)
🔥 Normal speed (low)
| Segment 1 | Segment 2 | Segment 3 | ||
|---|---|---|---|---|
| Ramp (°C/h) | 120 | 150 | 80 | End |
| Temp (°C) | 700 | 1120 | 1200 | |
| Soak (h.mm) | 0.00 | 0.00 | 0.30 |
Notes:
- Leave bung in from start to finish
- Open kiln when temperature is below 50°C
- Using a soak to achieve a ‘greener’ firing option in which energy and wear and tear on the kiln is less
🔥 Normal speed (mid)
| Segment 1 | Segment 2 | Segment 3 | ||
|---|---|---|---|---|
| Ramp (°C/h) | 120 | 150 | 80 | End |
| Temp (°C) | 700 | 1160 | 1220 | |
| Soak (h.mm) | 0.00 | 0.00 | 0.40 |
Notes:
- Leave bung in from start to finish
- Open kiln when temperature is below 50°C
- Using a soak to achieve a ‘greener’ firing option in which energy and wear and tear on the kiln is less
🔥 Normal speed (high)
| Segment 1 | Segment 2 | Segment 3 | ||
|---|---|---|---|---|
| Ramp (°C/h) | 120 | 150 | 80 | End |
| Temp (°C) | 700 | 1160 | 1240 | |
| Soak (h.mm) | 0.00 | 0.00 | 0.40 |
Notes:
- Leave bung in from start to finish
- Open kiln when temperature is below 50°C
- Using a soak to achieve a ‘greener’ firing option in which energy and wear and tear on the kiln is less
🔥 Slow more cautious
| Segment 1 | Segment 2 | Segment 3 | ||

| Temp (°C) | 680 | 1160 | 1220 | |
