I just got a used kiln and I am wanting to test it. I have been given some 015 kiln sitter bars and in reading about testing the kiln there was mention of using kiln wash on the sitter bar supports and the sensing rod. Not knowing what kiln wash was I tried to do some research and what I read tells me kiln wash is to keep glaze drips from sticking to the shelves. I am wanting to work with metal clay and (at this time) not glass or pottery. Do I need to use kiln wash and why would it need to be applied to the kiln sitter bar supports and sensing rod?
Thanks in advance
