You can use many kinds of cookware on glass cooktops as long as they have bottoms that sit flush on the burners to absorb the heat from the submerged heating elements. The best pots and pans for glass top ranges are good heat conductors, some types of which are often recommended by the cooktop manufacturers.
Heavier pots and pans made from clad stainless steel, anodized aluminum, cast iron or enameled cast iron make the best contact on glass-covered burners. The bottoms of cookware made from light gauge aluminum and stainless steel often become uneven over time and their poor connection with the burners makes foods cook unevenly or stick to the hot spots in the pans. Glass pots sit flat on the ranges but are not the best heat conductors.
Cookware Surface Requirements
Glass cooking surfaces are smooth and easy to clean but also fragile and prone to scratching. Run your hand over the bottoms of pots and pans before using them on glass top ranges to make sure there are no nicks or dents that could scratch the stove surface. If the rough spots are minimal, they can be buffed out with a diamond or glass nail file or fine steel wool. Avoid cookware with textured bottoms and pans that are painted or stenciled on the bottom as the former will scratch the cook top and make poor heat contact and the latter may permanently adhere to the stove's surface and impair or ruin its performance.
Pot and Pan Sizes
Use pots and pans appropriate to the sizes of the burners on the cook top. Many glass top ranges have outlines of pan sizes painted on the surface to use as guidelines. Using pans that exceed the size of the hidden burner will turn out food that is undercooked on the edges of the pans. Pans that are considerably smaller than the burner waste energy and the exposed heat from the burner's perimeter makes cooks' hands uncomfortably hot during meal preparation.
Glass Cook Top Tips and Hints
To prevent scratching glass cooktop surfaces, avoid dragging pans across them. Place pans gently on the burners as they can shatter from high impacts. To keep the conductivity of the stovetop at optimum levels, clean it with non-abrasive cleansers and cleaning pads to protect the factory finish and avoid damaging or erasing the temperature setting guidelines from the surface. To prevent foods from adhering to the cooktop, quickly wipe up food drips and spills.
