Please help, I am about to buy a kiln but I want to check it doesn't have asbestos in it. I have never owned a kiln before, so don't have a lot of experience. Does anyone know much about this model of kiln? Kilns and furnace TLB 223 harrier. The person I am buying it from thinks it was manufactured around 1999. I would be very grateful if anyone is able to help. Thank you!!
