Selecting types of cookware. GEAppliances.com The following information will help you choose cookware which will give good performance on glass cooktops. Use a pan that matches the diameter of the surface element you are using. Cooking performance will not be as good if the cookware itself is smaller or larger than the surface unit. Check pans for flat bottoms by using a straight edge. Stainless Steel: recommended Glass-Ceramic: usable, but not recommended Poor performance. May scratch the surface. 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. Stoneware: usable, but not recommended Poor performance. May scratch the surface. 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. Pans with rounded, curved, ridged or warped bottoms are not recommended. 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, since it may scratch the glass-ceramic cooktop. Do not place wet pans on the glass cooktop. For Best Results ■ Place only dry pans on the surface elements. Do not place lids on the surface elements, particularly wet lids. 9
