I'm trying to help an old friend by long distance with her kiln set up and decided to toss this question to the more experienced here on the forum: The kiln is a Jen Ken 2431 208v three phase rewired to a single phase. It runs off 70 amp breaker with 6/2 wire (very short run to breaker box). Resistance on element wires is 11. Has programmable controller ...Orton "Auto Fire" model. This is a three stack and the electrician involved recommended disconnecting the top element/stack. Any thoughts/advice would be appreciated. Thanks, -Paul
I thought I would start a new subject line rather than continuing to hijack the other one. I am trying to learn how to do some basic fine tuning of my glaze firing. I am going to start by trying to correct a pinhole issue I am having with one of my more popular glazes. I think the problem is that the temperature is dropping too quickly once reached and "freezing" the glaze before it has time to smooth out and heal over. I have a Bartlett V6-CF controller on my Olympic Kiln and I glaze fire to cone 6. With help from people over on the other subject of firing schedules (thank you!) I read through the Bartlett manual again. I read it when I first got it but didn't understand most of what I was reading so bad me for not reading it again. It seemed easiest to simply cut and paste the info from the Bartlett Manual so I don't get it wrong. This is their firing schedule for cone 6: Then I found this towards the back of the manual concerning a pre programmed vary fire program called User 6. They have something called a 16-S (16 segment program) under the menu section on the controller. I played around with the controller and was able to turn on this special, 16-S, user 6 cool down program. I do have a question concerning their Important Notes section. I am using the preprogrammed slow glaze cone fire program and the preprogrammed user 6 slow cool program. I don't see anywhere to do the segment adjustment they are saying to do. What am I not getting? Once I get the programming figured out my firing schedule should look like this if I am understanding it correctly: Slow Glaze Cone 6, 2232F 150 degrees per hour to 250 degrees 400 degrees per hour to 1982 degrees 120 degrees per hour to 2232 degrees Add on the Vary-fire User 6 Program (user 6 cone 6 cool down) Temperature starts at 2232 degrees F then cools at its natural rate to 1900 degrees F Then cools at 150 degrees F until it reaches 1500 degrees F at which point it then cools at its natural rate the rest of the way down to kiln opening temperature. Am I getting this right? Will adding this onto my slow glaze schedule help reduce pinholes? T
I consistently fire about a half cone cooler in the top and bottom of my Olympic 2327HE single zone kiln, Watching loading and shelf spacing helps but doesnâ€™t eliminate the situation. I was wondering if itâ€™s possible to simply add two new T/Cs and split the relay outputs to convert the Bartlett Controller to three zone control. As far as I can determine the actual controller board is standard and determines zone control based on how T/Cs are connected. Any help would be appreciated. Yes, I know this voids the warrenties.
