Hey Everyone, I'm so glad I found this forum. Been reading it for days now. Simple question here as I'm still figuring out my new to me 1985 (in good condition) small Cress kiln. Last evening's bisque firing was my 2nd attempt at low temp firing. I know what happened to first after call to Cress. Now for my 2nd attempt at bisquing: Timer set for 6 hours, speed control on E. The 04 cone in the kilnsitter did its job and bent (kiln turned off itself) The 04 witness cone did not bend. However, the witness cone is smaller and darker red. The greenware looks like it should after firing. Next time, I'll put an 04, 05 and 06 witness cone in to better gauge the true temp. And set time for 7 hours. My question is: if the 04 kilnsitter cone bent, why didn't the witness cone. Should I have continued to manually fire until witness cone bent? Any advise or thoughts is appreciated.
