I canned on my glass top stove last fall. I didn't have any problems. I had bought a new pressure canner and it had the outer edges of the bottom raised off of the burner. The book that came with the canner said it is safe to use on the smooth top stoves. I like the cleanup part, but I have a had time keeping my pans right on the burner. Seems like I always have to keep looking and moving the pan. It slides if I stir anything.
