Microwaves are generated in the microwave oven by a magnetron and cause the water molecules in the
food to oscillate. Heat is generated by the friction which is caused, with the result that the food is thawed,
heated or cooked.
GLASS AND CERAMIC GLASS
Heat-resistant glass utensils are very
suitable. The cooking process can be
observed from all sides. They must
not, however, contain any metal (e.g.
lead crystal), nor have a metallic
overlay (e.g. gold edge, cobalt blue finish).
CERAMICS
Generally very suitable. Ceramics must be glazed,
since with unglazed ceramics moisture can get into
the ceramic. Moisture causes the material to heat up
and may make it shatter. If you are not certain
whether your utensil is suitable for the microwave,
carry out the utensil suitability test.
PORCELAIN
Very suitable. Ensure that the porcelain does not have
a gold or silver overlay and that it does not contain
any metal.
PLASTIC AND PAPER UTENSILS
Heat resistant plastic utensils which are suitable for use
in the microwave can be used to thaw, heat and cook
food. Follow the manufacturer's recommendations.
Heat-resistant paper made for use in a microwave
oven is also suitable. Follow the manufacturer's
recommendations.
KITCHEN PAPER
can be used to absorb any moisture which occurs
in short heating methods, e.g. of bread or products
in bread crumbs. Insert the paper between the food
and the revolving plate. The surface of the food will
stay crispy and dry. Covering greasy food with
kitchen paper will catch splashes.
MICROWAVE CLING FILM
This, or heat-resistant film, is very suitable for covering
or wrapping. Please follow the manufacturer's
recommendations.
ROASTING BAGS
Can be used in a microwave oven. Metal clips are
not suitable for fastening them since the roasting bag
foil might melt. Fasten the roasting bag with string and
pierce it several times with a fork. Non heat-resistant
food wraps are not recommended for use in a
microwave oven.
WHAT ARE MICROWAVES?
SUITABLE OVENWARE
BROWNING DISH
A special microwave dish made from ceramic glass with
a metal alloy base, which allows food to be browned.
When using the browning dish a suitable insulator,
e.g. a porcelain plate, must be placed between the
turntable and the browning dish. Be careful to adhere
exactly to the pre-heating time given in the
manufacturer's instructions. Excessive pre-heating can
damage the turntable and the turntable stand or can
trigger the safety-device which will switch off the oven.
METAL
Generally speaking, metal should not be used, since
microwaves do not pass through metal and therefore
cannot reach the food. There are, however, exceptions:
small strips of aluminium foil may be used to cover
certain parts of the food, so that these do not thaw too
quickly or begin to cook (e.g. chicken wings). Small
metal skewers and aluminium containers (e.g. of ready-
cooked meals) can be used. They must, however, be
small in relation to the food, e.g. aluminium containers
must be at least
recommended that you transfer the food into a dish
suitable for use in the microwave. When using
aluminium containers or other metal utensils there must
be a gap of approx. 2 cms between them and the
walls of the cooking area, otherwise the walls could be
damaged by possible arcing.
NO UTENSIL SHOULD HAVE A METAL

UTENSIL SUITABILITY TEST
If you are not sure whether your utensil is suitable for
water on or next to the utensil. Switch on the oven at
800 W power for 1 to 2 minutes. If the utensil stays
cool or just warm to the touch, it is suitable. Do not
use this test on a plastic utensil. It could melt.
