Cookware - Whirlpool  GW397LXUQ Use & Care Manual

IMPORTANT: Do not leave empty cookware on a hot surface
cooking area, element or surface burner.
Ideal cookware should have a flat bottom, straight sides and a
well-fitting lid, and the material should be of medium-to-heavy
thickness.
Rough finishes may scratch the cooktop or grates. Aluminum and
copper may be used as a core or base in cookware. However,
when used as a base they can leave permanent marks on the
cooktop or grates.
Cookware material is a factor in how quickly and evenly heat is
transferred, which affects cooking results. A nonstick finish has
the same characteristics as its base material. For example,
aluminum cookware with a nonstick finish will take on the
properties of aluminum.
Cookware with nonstick surfaces should not be used under the
broiler.
Use the following chart as a guide for cookware material
characteristics.
