11Cookware TipsHalogen/Radiant CooktopTypes ofcookwareThe following information will help you choosecookware which will give good performance.Stainless Steel: recommendedEspecially good with a sandwich clad bottom.The sandwich bottom combines the benefits ofstainless steel (appearance, durability andstability) with the advantages of aluminum orcopper (heat conduction, even heatdistribution).Aluminum: heavy weight recommendedGood conductivity. Aluminum residuessometimes appear as scratches on the cooktop,but can be removed if cleaned immediately.Because of its low melting point, thin weightaluminum should not be used.Copper Bottom: recommendedGood performance, but copper may leaveresidues which can appear as scratches. Theresidues can be removed, as long as the cooktopis cleaned immediately.However, do not let these pots boil dry.Overheated metal can bond to glass cooktops.An overheated copper bottom pot will leave aresidue that will permanently stain the cooktopif not removed immediately.Porcelain Enamel Covered Cast Iron:recommendedGood conductivity. As long as the cookware iscovered completely with porcelain enamel, thiscookware is recommended. Cast iron retainsheat, maximizing energy efficiency, andprovides smooth, even heat distribution.Caution is recommended for cast ironcookware that is not completely covered withsmooth porcelain enamel, as it may scratch theglass ceramic cooktop.Glass-ceramic: usable, but not recommendedPoor performance. May scratch the surface.Stoneware: usable, but not recommendedPoor performance. May scratch the surface.For bestresults• Place only dry pans on the surface units. Donot place lids on the surface units, particularlywet lids.• Do not use woks that have support rings. Thistype of wok will not heat on glass surface units.• We recommend that you use only a flat-bottomed wok. They are available at yourlocal retail store. The bottom of the wokshould have the same diameter as thesurface unit to insure proper contact.• Some special cooking procedures requirespecific cookware such as pressure cookers,deep fat fryers, etc. All cookware must haveflat bottoms and be the correct size.Do not place wet pans on the glass cooktop.Do not use woks with support rings on the glass cooktop.Use flat-bottomed woks on the glass cooktop.
