I can't speak to the heavy pressure canner on the glass top, but I destroyed our glass top stove with a water bath canner, last fall. The bottom of the pot was not flat, and when it started popping with the heat(something I'd never even noticed, on any other stove top), it cracked the glass, which then completely cracked with the subsequent 2 quick cookings on it. We've decided that when we build our Walker, we will use a heavy steel flat-top.
