I recently purchased a used but never fiired aim kiln and needed technical help. They are not helpful at all. They only communicate by email which makes it hard. I found the "technician"rude and very condescending. I found out he wasn't a potter maybe that was why he couldn't seem to offer any help other than buying extra insulation. I wanted some help with the firing schedule. I felt they misreprested their product. It is rated cone 10, but I am struggling to reach that temp. The technition told me I probably wouldn't be ably to reach that temp without buying extra insulation and an extra lid. I found that ridiculous considering it is an updraft cone 10 gas kiln that has been installed by professionals according to the aim manual. I found them to be not only unhelpful but very unprofessional. I would not buy an aim kiln based on my experience. Does anyone have any ideas how to get a little more heat? I got to 2190 but then it wants to stall out and begins to drop. I'm considering drilling out the orifices a little larger to get more gas. Thanks to anyone who has some ideas!
