I'm new to this forum and happy to become a part of the community.
To start off with, I recieved a small kiln (11"W x 11"L x 9"H) from a friend and have been firing bisque in it. I am a noob at fiing, so this has been all new to me. The kiln is a CRESS brand kiln with a kiln sitter and has a "firing duration" knob. (See attached image) It also has a thumb wheel that automatically progresses from 0 to 10 which controls the heat intensity. When I fire bisque, it takes about 5 - 6 hours to fire to cone 06.
The problem occurs when I try to highfire to cone 6. I put the cone in the kiln sitter and set the time knob to about 12 hours, but it is not enough. Then, the heat intensity thumb wheel seems to get stuck at level 4, so I have to manually ramp it up to 6, and then to 8, and then to 10 every few hours. Finally, when it is at level 10, it stays that way for about 6 hours, and the cone does not drop. I keep returning to a kiln full of porous wares and an un-triggered kiln sitter. Is there something that I am doing incorrectly?
I am really enjoying being able to creat and fire my own ceramic objects and would really like to make this kiln work. I have purchased plenty of kiln shelves and posts for this kiln and would like to prevent having to buy a new kiln of a different size. Could the kiln that I am using be malfunctional? If so, would it be the coils, the kiln sitter controls, or the electrical box that is to blame? Any help with this is greatly appreciated.
I am attaching a few fotos of the kiln for reference.
P.S. Can anyone tell me what that yellow-orange button on the panel does? I always have it pressed and lit when firing.
