Selecting Types of Cookware
The following information will help you choose cookware which will give good performance on glass cooktops.
Check pans for flat bottoms by
using a straight edge.
Pans with rounded, curved, ridged
or warped bottoms are not
recommended.
Use only flat-bottomed woks.

Stainless Steel:
recommended
Aluminum:
heavy weight recommended
Good conductivity. Aluminum residues
sometimes appear as scratches on the
cooktop, but can be removed if cleaned
immediately. Because of its low melting
point, thin weight aluminum should not
be used.
Copper Bottom:
recommended
Copper may leave residues which can
appear as scratches. The residues can be
removed, as long as the cooktop is
cleaned immediately. However, do not let
these pots boil dry. Overheated metal can
bond to glass cooktops. An overheated
copper bottom pot will leave a residue
that will permanently stain the cooktop if
not removed immediately.
Porcelain Enamel Covered Cast Iron:
recommended
As long as the cookware is covered
completely with porcelain enamel, this
cookware is recommended. Caution is
recommended for cast iron cookware
that is not completely covered with
smooth porcelain enamel, as it may
scratch the glass ceramic cooktop.
Wok Cooking
We recommend that you use only a flat-bottomed
wok. They are available at your local retail store.
Do not use woks that have support rings.
Use of these types of woks, with or
without the ring in place, can be
dangerous. Placing the ring over the
surface unit will cause a build-up of heat
that will damage the porcelain cooktop.
Do not try to use such woks without the
ring. You could be seriously burned if the
wok tipped over.
Glass-ceramic:
usable, but not recommended
Poor performance. May scratch the
surface.
Stoneware:
usable, but not recommended
Poor performance. May scratch the
surface.
