General Electric recommends stainless steel or aluminum cookware for use on radiant, smooth glass cooktops. The pans should be medium or heavy weight, and they should have flat bottoms to facilitate optimal heat transfer.
Pans with a copper bottom are also suitable, but they often leave a residue that requires cleaning immediately after use. If a pan with a copper bottom boils dry on a glass cooktop, it can leave a permanent stain. Porcelain or enameled pans also perform well on glass cooktops, but the porcelain may melt and damage the glass surface if overheated. Stoneware, glass and ceramic are not recommended for use on glass cooktops, and cast iron cookware is only suitable if it has an enamel coating.
