The glass stove top is made of a glass-ceramic blend that provides the stove top with the strength and heat-resistance needed to sit atop heating elements. The glass in the stove top is cooled before undergoing a special heat treatment to partially crystalize the glass. The end result is a piece that can expand and contract with the heat, as need be, without being as porous as traditional ceramic.
