A test of insulation and mass.

[Joe Campbell]

Saturday I fired the oven and at one point the ceiling was near 1200F degrees. Sunday morning when we woke up, we had about an inch of snow, even on the roof of the oven. I had not put the door in place either. Outside air temp was in the 20s. Inside the oven, the floor was about 190F and the ceiling was 310F. This was 14 hours after baking pizzas.

Excellent. What details can you provide about your oven related to insulation, materials, mass??
