Cookware
Suitable cookware
Cookware should have a stable bottom. When heated, the base of the cook-
ware must lie flat on the surface of the cooking zone.
Cookware made of metal is more suitable than that made of glass or ceramic
as with metal the heat is distributed evenly quicker.
Cookware bases made of aluminium or aluminium alloys can leave stubborn
marks on the glass ceramic surface that are very difficult to remove.
Energy-efficient cooking
For maximum energy efficiency and even heat distribution note the following:
▪
The base of the cookware must be clean, dry and smooth.
▪
Centre the cookware in the middle of the cooking zone.
▪
Use a well-fitting lid.
▪
Match the diameter of the cookware to the quantity of food to be cooked.

OptiGlass
Applies to GK43O, GK43FO, GK43UO
Hobs with OptiGlass have an additional coating on the glass surface.
This coating makes the surface harder, tougher and more scratch resistant
than non-coated glass surfaces.
Under normal circumstances, significantly fewer scratches should oc-
cur on the glass surface during cooking. However, even a sharp grain
of sand or particle of grit, for example, under a pan can cause
scratches.
Illumination
▸ Halogen or LED light bulbs are recommended for illuminating hobs with the
OptiGlass coating.
The use of fluorescent tube lighting to illuminate hobs with the Opti-
Glass coating causes the glass surface to shimmer.
