Process & Production

Unlike ordinary concrete, the fireproof concrete stands temperatures up to appr. 1400°C. High temperatures allows us to sinter porcelain and melt glass. Please find the firing sequence below.

Recipe Details

Firing sequence for refractory concrete, combined with Bullseye glass, full melting 1220 degrees.
Porcelain clay slip as an insulating layer between the concrete and the glass.
1. 0 – 150°C – Time: 6 hrs – Hold: 6 hrs
2. 150 – 300 °C – Time: 6 hrs – Hold: 1 hour per 25 mm material thickness
3. 300 – 1220 °C – Time: 14 hrs – Hold: 0 hrs
4. 1220 – 540 °C – Time: 0 hrs – Hold: 4 hrs
5. 540 – 450 °C – Time: 2 hrs – Hold: 1 hrs
6. 450 -0 °C – Time:06 hrs – Hold: 0 hrs
Total firing time = approx. 43 hours + cooling phases (approx. 3 days)
Only open the kiln when it is below 100 degrees (due to tension in the glass)
