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.
\nI 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\u00a0 waiting for it to shut off.<\/p>\n
I saved the firing profile as user 6 to use again as-is if the load turns out fine.
\nI set the timer clock on the vent fan to turn off in about an hour, so tomorrow afternoon I should be able to open it up and see what I have, hopefully I won’t have four shattered lion faces staring up accusingly at me from the bottom of the kiln!<\/p>\n
The program I came up with was 7 stages and started off with a 6 hour preheat @ 200 degrees F with a temperature rise of 60 degrees per hour, so it took about 2 hours to get to 200 degrees.<\/p>\n
Then it continued with segments 2 through 7:<\/p>\n
S2- 80 deg\/hour to 280 deg
\nS3- 100 deg\/hour to 550 deg
\nS4- 80 deg\/hour to 750 deg
\nS5- 150 deg\/hour to 1100 deg
\nS6- 180 deg\/hour to 1700 deg
\nS7- 80 deg\/hour to 2060 deg with a 10 minute hold @ 2060 deg.<\/p>\n
