the ceramic glass plate.

board or plastic on the oven. Objects such as tin,
zinc, or aluminium (as well as aluminium foils or
empty coee pots) may melt on hot cooking surfac-
es and thus cause damage.
7. Take care not to let sugary foods or fruit juices
contact the hot cooking zones. The ceramic glass
surface may be stained by these.
