So the kiln hit 2030 or so degrees at about 9:15. I had to shut it off. I think it should have shut itself off, but I'm not sure. There is some difference between the cone types and the temperature they bend at. The cone had not bent at 2030. So ... this will need to be tested again. This time it will be at cone 04 which the chart shows at 1915 to 1971 degrees. That'll take less time and I want to fire a glaze next time. The glaze I got is a cone 04 glaze.

Need to figure out where the computer runs relative to the chart and if it compensates for heating rate. Oh, this was all at the medium or standard heating rate.
It's about 1:15 a.m. now and it's down to 868 degrees. No longer glowing inside.
The front of the control box probably got up to 150. The shed stayed cool to the touch actually. The top of the shed was warm, but not at all hot.
Good night.
