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 coils. 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
surfaces.
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.
Check for flatness by placing the straight edge of a ruler across
the bottom of the cookware. While you rotate the ruler, no space
or light should be visible between it and the cookware.
Use the following chart as a guide for cookware material
characteristics.

heating.
Use flat-bottomed cookware for best cooking results and energy
efficiency. The cookware should be about the same size as the
cooking area outlined on the cooktop. Cookware should not
extend more than
/
" (13 mm) outside the area.

Home Canning
Canning can be performed on a glass smooth-top cooking surface
or traditional coil element cooktop. When canning for long periods,
alternate the use of surface cooking areas or elements between
batches. This allows time for the most recently used areas to cool.
Center the canner on the largest surface cooking area or
■
element. On electric cooktops, canners should not extend
more than
/
" (13 mm) beyond the surface cooking area

or element.
Do not place canner on 2 surface cooking areas or elements at
■
the same time.
On ceramic glass models, use only flat-bottomed canners to
■
avoid damage to the cooktop and elements.
For more information, contact your local agricultural extension
■
office or refer to published home canning guides. Companies
that manufacture home canning products can also offer
assistance.
