What Type of Cookware Is Best for Use on a Glass-Top Range?

Glass-top ranges have heating elements underneath the glass surface. A pan with a flat bottom stays in better contact with the heat source to cook food evenly. Rounded pans and pans with irregularities are a poor choice. The glass cook-top is also vulnerable to scratching. Cast iron and other cookware with rough surfaces easily scratch the range when they are placed on the stove or moved from one place to another.
