Cookware
Use of correct cookware can affect the cooking
performance and cleaning of your cooktop. The
correct cookware reduces the temperature of the
Use pans with thick, flat, smooth bottoms. Slightly
concave pans give acceptable results. Do not expect
good results from convex bottom pans. To check the
flatness of your pan try one of the the following tests:
1. Turn the bottom of the pan up.
Place the edge of a ruler across
the bottom of the pan. Little or
no light should be visible
under the ruler.
The following information will help you choose
cookware which will give good performance.
Stainless Steel: highly 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: heu~j' 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:
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.
2. 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.
Porcelain/enamel:
Good performance only with a thick, flat, smooth
bottom. Avoid boiling dry, as porcelain can melt and
fuse to the surface.
Glass-ceramic: not recommended
Poor performance. May scratch surface. Usable, but
not recommended.
Stoneware: not recommended
Poor performance. Will scratch the surface.
Cast Iron: not recommended
Poor performance. Will scratch the surface.
