The kiln shut off just about the time I figured on after 24 hours and 20 minutes. I watched it just hit 2061 degrees and then it went to the 10 minute hold. I was able to calculate the temp rise in the last stage of 80deg/hour to be 1.333 degs per minute and the Bartlett controller kept it just about dead on, and shut off almost to the minute I had calculated while I was  waiting for it to shut off. I saved the firing profile as user 6 to use again as-is if the load turns out fine. I set the timer clock on the vent fan to…

Here’s what I programmed in the kiln controller for another round of torture tests, and yes, it’s a form of torture to open a kiln lid, look inside and see your work ruined: Segment / Temp rise per hour/ Temp in degrees  F -60 to 200 (hold for 6 hours) -80 to 280 -100 to 550 -80 to 750 -150 to 1100 -180 to 1700 -80 to 2060 Hold: 10 minutes That make it about a 24 hour firing plus the cooling down.
