Steve, your comments on the cleaning cycle exactly matched my logic. There has to be some little old lady with OCD that feels that she needs to clean her oven twice a week so the manufacturer has to build it for that. Plus the actual cleaning cycle exceeds the temp on my Raytek (which is 975). I don't know by how much. But by opening the door and baking, yada, yada, it never really gets up to that and I shut it down well before the full 3 hour cleaning cycle.
That said, Randy you could certainly have a point about reaching the failure point over time. I hate to admit it, but it's possible. I have a fire extinguisher nearby, but I know that's not the best option in the world. Your electrocution point is also possible, I guess.
The cigar tube thing really scared even me. But I tried something nearly identical once. LOL... We are crazy. I used a pool of water in foil. I even did the whole unscrewing of the guage thing to dunk it. I have shattered the glass on my door twice by getting it wet with sauce. That was pretty scary. My advice on covering the door with foil very loosely is serious advice. Please do that.
Do they make urns shaped like pizza boxes? Can I be creamated in patsy's oven? Well, at least I don't smoke or run with scissors.
