Oven floor heat

[mgraban]

I burned my 4th curing fire today, the oven dome reached just over 400F, burned just a few logs in the front/center of the oven.

After about 75 or 90 minutes, I pushed the fire to the side and measure my floor temp under where the fire had been:

1:00 PM 620 F
1:15 PM 400
1:30 PM 319
1:45 PM 300
2:00 PM 274
2:15 PM 244

With a very small minimal (burning out) fire and embers, that was the cooling profile of the oven floor.

Anyone else ever taken measures like that? I have the SuperIsol underneath the oven floor for insulation. Seem about right?
