Stoneware glaze firings

Stoneware glaze firings

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
Ramp (°C/h) 100 120 80 End
Temp (°C) 680 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
