What cookware is not really suitable?
Glass ceramic, because it has poor heating properties and therefore results in unsatisfactory cooking results. In principle, you can use glass cookware on your CERANĀ® cooking surface, although it is preferable to use glass-ceramic cooking vessels; however, you must make sure they are flame-proof. In order to prevent scratches on the cooking surface, the bottom of the cookware should not have ridges. Take care with aluminium: if traces are not immediately removed with an appropriate cleaning agent they may burn onto the surface and mar its appearance.
