Control Knobs Cookware Tips
The following information will help you choose
cookware which will give good performance.
Stainless Steel: recommended
Especially good with a sandwich clad bottom. The
sandwich bottom combines the benefits of stainless
steel (appearance, durability and stability) with the
advantages of aluminum or copper (heat conduction,
even heat distribution).
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
Good performance, but 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
Good conductivity. As long as the cookware is covered
completely with porcelain enamel, this cookware is
recommended. Cast iron retains heat, maximizing
energy efficiency, and provides smooth, even heat
distribution. Caution is recommended for cast iron
cookware that is not completely covered with smooth
porcelain enamel, as it may scratch the glass ceramic
cooktop.
Glass-ceramic: usable, but not recommended
Poor performance. May scratch the surface.
Stoneware: usable, but not recommended
Poor performance. May scratch the surface.

How to Check Pan Performance
Use of correct cookware can affect the cooking
performance and cleaning of your cooktop.
The correct cookware reduces the temperature of
the cooktop surface and minimizes the chance of
spillovers burning onto the cooktop.
You must use pans with perfectly flat bottoms.
Some pans may have curved or rounded bottoms or
may be warped. If you are unsure of the flatness of
your pans you may do this quick test.
Turn your pan upside
down on the countertop,
place a ruler flat against
the pan surface. The
bottom of the pan and the
straight edge of the ruler
should fit flush against each other all the way across.
Turn the ruler a full 360 degrees, checking for any
space between the ruler and the bottom of the pan.
Pans with rounded, curved, ridged or warped bottoms
are not recommended.
Another simple test to determine even heat distribution
across the cookware bottom is to put one inch of water
in the pan. Bring the water to a boil and observe the
location of bubbles as the water starts to boil.
Good flat cookware will have an even distribution of
bubbles over the bottom surface area of the pan.
Bubbles localized in only a portion of the bottom
indicate uneven contact of the pan to the surface unit,
uneven heat transfer or an unsuitable pan.
Use pans that match the diameter of the surface
unit. Cooking performance will not be as good if
the cookware is either smaller or larger than the
surface unit.
