I thought I was going to be the single bad exception here but I guess not.
I have a brick kiln, on a stainless steel table, away from the walls in the garage. I get so little sleep as it is if I had to stay up and wait for it there would go the rest of the sleep I could get
I ran home at lunch today and was able to make six beads (we had a gas leak at work) I had no problem leaving the kiln on. I know it will be just the right temp when I get home to remove my beadies and start fresh!!!
