  1. Room Temperature during glaze firing

    Hmmm... that's an interesting thought. I don't think I've ever stacked so many shelves with so many plates before. I usually have a lot of bowls and mugs and pack it pretty tightly but with only 4 layers of shelves. Sometimes an extra 1/2 shelf with small plates at the top if I can fit it. I will be running another glaze kiln in a few weeks - I will be sure to put taller items with less shelves in it. Thank you EVERYONE for all of the input. It's so comforting to know that there are so many potters in the world with so much experience and information.

    I'm guessing that perhaps it's the lid - not sure what else it could possibly be. I'm wondering if my elements are going, the firing did take a lot longer than usual. BUT the kiln had a heavy load - it was packed loosely with wares, but I had 6 1" shelves stacked with plates. SO according to Skutt techy that's a pretty dense load due to the shelves. I'm starting to wonder if a "vent-a-Kiln" might be helfpul for this problem. Has anyone ever used one? And do you think it will address this problem?

    We vented the a/c out of the barn. We did trim a hedge last fall, however, the problem occurred at night and it was 50 degrees outside. So I don't think it was either of those issues. I did talk to a Skutt technician and he thinks the issue is with the lid not being seated evenly on the kiln. He had me adjust the lid. And suggested that I put some kiln shelves on top of the lid the next time that I run the kiln. At this point this is the plan I suppose. I will give it a shot and see what happens.
  4. Room Temperature during glaze firing

    hmmmmm.......lots to think about. Here's more of the whole story - 2 weekend's ago I ran a glaze kiln. Packed tight! The room got to 130 degrees, the controller went into error mode. I cooled down the room to 80 degrees and did a restart. Checked on the kiln constantly until it was done. It ended up going to a perfect cone 7 instead of cone 6. Not such a terrible thing except that all of my cone 5/6 glazes got a bit runnier and darker than expected. SO the examination began. We took apart the vent to clean it out and make sure that there weren't any bird nests in the hose. When we took it apart it became apparent that the hose was split and the cup under the kiln had not been lined up to the kiln holes properly. (I'll be more careful vacuuming under the kiln from now on.) So I thought this was the obvious reason that the room got so hot - the vent hose was dumping heat directly into the room. SO we fixed the vent - new hose, new gaskets, lined it up to the best of our ability and purchased a free standing a/c unit. Fast forward 1 week - loaded the kiln again, packed it loosely this time. Expecting it to be a perfect firing. ( I actually baked a birthday cake for the re-birth of the kiln and good karma) Right! Started the cone 6 glaze firing and kept a constant watch on it every hour. At about 1100 degrees the room started to creep up to 90 degrees - so I started the a/c unit. And yes, it was blowing on the controller vents side. With just the a/c on the room didn't cool down very much. So we setup all the fans again, opened the window and door to get a cross vent and ran the a/c on the controller. This managed to keep the room at a steady 84 to 86 degrees through the firing. In the past 6 years I have never had a problem where the room temp climbs so high. I'm trying to determine what has changed to cause this. I'm thinking that it must have something to do with the lid and heat leaking through the gap into the room. Not sure about the insulation - I will check on that. This studio space is an ongoing project that we keep working on. I'll check with my husband to see if he changed anything with the insulation - I don't think that 's the case.

    The control panel is already facing the open room. I actually had the portable a/c blowing on the controller. I'm just baffled as to what has changed since the last glaze firing. I've run this kiln so many times w/o this problem. There must be something that has changed. I'll thoroughly examine the top of the kiln and the lid after I unload. Thank you for the input. I do have a few spots on the lip of the kiln that need some brick repair - that might be the problem.

    That's really helpful information. Thank you. When this firing is finally finished and unloaded I will do a thorough inspection of the tip bricks and the lid. Do you know if the Skutt lid master has adjustments that allow it to be tightened? I will give a call to Skutt tech support tomorrow to see what they suggest.
  7. Room Temperature during glaze firing

    The room is about 350 sq. ft with a 10 ft. ceiling. It's a good sized pole barn that was turned into a studio. I can see a red glow through the crack of the lid when the kiln is running. One side of the kiln has a bit of a larger opening than the other, and that side of the room of the kiln is definitely hotter when it is running.
  8. Room Temperature during glaze firing

    The outside temperature was about 50 degrees. The windows and doors were all open with a cross breeze. I had 4 fans running - 1 ceiling fan and 3 floor fans - to create air movement. The kiln is towards the back of the room. However, I have fired this kiln at least 12 times per year for the past 6 years and this is the first that this has happened. To keep the problem at bay, we hooked up a portable A/C unit. It was kind of crazy - the unit kept the air temp down as long as the doors and fans were also open and running. When we closed up the room and kept the A/C unit on, the temp was slowly and consistently creeping up. So we left all doors open, fans on and A/C running through the night. It kept the temp at around 85 degrees. But why is this happening? I fear that the cost of running all these cooling devices will be prohibitive. In the past I have run the glaze firing in the summer with out this problem. Any ideas of what has changed to cause such temperature differences in the room? I'm trying to determine if it has something to do with the Vent Master or the Lid. Can't seem to figure it out.
  9. Can anyone tell me why this is happening. I have a Vent Master down draft on the kiln - it just had parts replaced. The room temperature is creeping up to 100 degrees and have to run many fans, doors open to keep it at bay. Last week's firing got so hot in the room that the controller shut down and I had to do a re-fire. Could this be a problem with the lid? I have had this kiln for 6 years and have never had this problem before. Any insight is greatly appreciated.
