I'm not positive, as I have a gas stove, but my Sister-in-Law has a glass top. I gave her an older set of copper bottoms when I upgraded my cookware. LAter, when a repairman came by, he commented that the copper-bottoms are perfect for the glass top electric stoves because the bottoms are so flat and sit well on the surface. Plus, the heat distributes well, so even if the burner is smaller than the pot, it should heat fairly evenly.
