Hi everyone, ive been reading on this bulletin and think I know what to do now, but need some extra advice.
I'm a new middle school art teacher, and not as versed in ceramics as I should be. BUT I love it and know enough, however the kiln I'm using seems off? I used a sitter bar and cone for my 04 bisque (earthenware, white). I was adviced by the previous teacher to run it on high for only 4 hours, and to set the timer to 8 hours. (Low for 2, Medium for 2 and high for 4.) Well the cone never bent, and the sitter never shut it off, and so i kinda panicked because it's our first project
