Types of CookwareThe following intbrmation will help you choosecookware which will give good performance.Stainless Steel: highly recommendedEspecially good with a sandwich clad bottom. Thesandwich bottom combines the benefits of stainless steel(appearance, durability and stability) with the advantagesof aluminum or copper (heat conduction, even heatdistribution).Aluminum: heavy weight recommendedGood conductivity. Aluminum residues sometimesappear as scratches on the cooktop, but can be removedif cleaned immediately. Because of its low melting point,thin weight aluminum should not be used.Copper Bottom: heavy weight recommendedGood performance, but copper may leave residues whichcan appear as scratches. The residues can be removed,as long as the cooktop is cleaned immediately.Porcelain/enamel:Good performance only with a thick, fiat, smoothbottom. Avoid boiling dry, as porcelain can melt andfuse to the surface.Glass-ceramic: usable, but not recommendedPoor perforraance. May scratch surface.Stoneware: usable, but not recommendedPoor performance. May scratch surface.Cast Iron: usable, but not recommendedPoor perfo_raance. May scratch surface.• We recommend that you _..... ,use only a fiat-bottomed wok.They are available at your localretail store. The bottom of thewok should have the samediameter as the surface unit toinsure proper contact.• Do not use woks that havesupport rings. This type ofwok will not heat on radiantsuFfaces.• Some special cooking procedures require specificcookware such as pressure cookers, deep fat fryers, etc.All cookware must have fiat bottoms and be the correctsize. The cookware should also be covered, ifapplicable to the cooking process.
