I'm looking at different firing schedules for my kiln.
One I've looked at begins as follows:
1st ramp @ 50°F per hour to 220°F
I work in centigrade with my kiln so this converts to:-
1st ramp @ 10°C per hour to 104°C
If we start with an ambient temperature of 70°F it will take 3 hours to reach 220°F
Convert that to Centigrade:-
If we start with an ambient temperature of 20°C it will take 8 hours+ to reach 104°C
What am I missing?
