I didn't realize I needed them until a few months ago I forgot to remove the porcelain coated still from our glass top. There was very little liquid left in the pot and it got so hot that the bottom of the pot deformed so much that the glass underneath shattered. This completely damaged the stove and pot. I have used these (2) heat spreaders under a stainless steel pot and another porcelain coated pan on our new glass cooker with no problem.
