Cookware
Suitable cookware
Cookware should have a stable bottom. When heated, the base of the cookware 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 occur 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 OptiGlass coating
causes the glass surface to shimmer.
