hello I have just purchased a second hand cromartie hobbytech 40 kiln with an lt3k kiln sitter, having never fired my own work (I have always had a technician do it) I was wondering about the ramping speed to fire stoneware. The kiln has a dial on the side from 1 to 4 and then full, I was wondering how long I should leave between each increase in power. as I understand it too quick an increase in temperature could cause the clay to break due to the steam. here is a picture of the kiln dial. also the Kiln has a peep hole in the side and a vent hole on top, should I leave both open during firing? regards Liam
My controller does not have a preheat programme. What ramp would I set to get an equivalent? I can programme this onto the beginning of the programmes I have entered. Not having any real trouble without it but occasionally I fire thicker handmade pieces and I do glaze load and fire on the same day.
Hi all, I haven't been able to find any firing instructions for my old AIM kiln. Even the folks at AIM said they didn't have any . So I'm left with power dials that go from 1 to 10, and no idea how that translates into temperature. I'd like to be able to test this kiln without spending money on a temperature gauge/controller only to discover that what I really need is a new kiln. I have a bunch of different low fire cones, and was thinking of using them as a visual guide for reaching temperatures, but the more I think about it the more I imagine endless permutations of dial-adjustments matched to cone-slumps and time-monitoring. Am I crazy to think I could do a ramp/soak firing without having even a temperature gauge? Thanks, Matt
Anyone advise me on the advisability/dangers to fast firing of cone 6 oxidation glazes? I don't mean soak or hold times, just how quickly I bring the kiln up to temp. What little training I ever received in firing only differentiated bisque and glaze firings by the desired temp or cone, not the length of the firing. So I've always ramped up slowly, bisque or glaze. My consideration here is not just time, but the expense of lengthy firings. If I can shave a few hours off a glaze firing without compromising my results, then it just makes sense. Any advise much much appreciated.
