OptiGlass
Applies to GK47TIMSCO, GK47TIMSZO
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.
