Microwave function only
Utensils and cooking containers used in a microwave oven
should be of a material that does not act as a barrier to
microwave energy. Generally this means that you should cook in
either (paper), plastic, glass or ceramic. Metal pans reflect
microwave energy and inhibit cooking, and should not be used.
In addition to material, the shape of the container should also be
considered. Round oval shapes give the most even cooking.
Square or rectangular containers may over-cook foods in the
corners because more energy is absorbed there.
Shallow containers give more even cooking results.
Utensils made of china and ceramic excellent to use in your
microwave oven. Most types of glass are also very good.
Lead crystal glass can crack and should therefore, not be used.
Plastics and paper can also be used, provided they can
withstand the temperature of the heated food. For cooking only
use plastics, which will withstand a temperature of over 120˚C,
e.g. polypropene and polyamide. Some plastic materials, e.g.
melamine, will be heated by the microwave, and be damaged. To
find out if a certain container is suitable, the following simple test
can be made:
Place the empty container and a glass of water inside the
microwave oven. The water is needed because the oven must
not be operated empty or with empty containers only.
Let the oven work on full power for one minute. A suitable
container will only be lukewarm.
Metal containers, e.g. saucepans or frying pans should not be
used in microwave ovens. Nor should plates or vessels with
decorations be used since metal e.g. gold, might be part of the
decoration and such decorations will be damaged.
Small pieces of aluminiuum foil can be
used, but only to shield the areas that
would over-cook (e.g. for covering chicken
wings, leg tips and fish tails) but the foil must
not touch the side of the oven as damage
may occur.
TO AVOID EXPLOSION AND SUDDEN BOILIING
1. Eggs
Never cook eggs in their shells. Steam will build up inside the
shell during cooking and the egg will explode.
If you want to cook or reheat eggs which have not been
broken up by scrambling or mixing, you must always pierce
the yolks or these will also explode. You should slice shelled
hard boiled eggs before you reheat them in your microwave
oven.
2. Piercing
Always pierce food which has a skin or membrane, for
example, potatoes, tomatoes, apples, sausages etc. If you
don't pierce them, steam will build up inside and they may
explode.
3. Lids
Always remove the lids of jars and containers and take away
food containers, before you cook using your microwave oven.
If you don't, then steam and pressure might build up inside
and cause an explosion even after the microwave cooking has
stopped.
WHICH UTENSIL CAN BE USED IN THE OVEN?
WARNING
When heating liquids, e.g. soups, sauces and beverages in
your microwave oven, overheating the liquid beyond boiling
point can occur without evidence of bubbling:
This could result in a sudden boil over of the not liquid.
To prevent this possibility the following steps should be taken:
a. Avoid using straight sided containers with narrow necks.
b. Do not overheat.
c. Stir the liquid before placing the container in the oven and
again halfway through the heating time.
d. After heating, allow to stand in the oven for a short time, stir
or shake them again carefully and check the temperature of
them before consumption to avoid burns (especially,
contents of feeding bottles and baby food jars).

1. Without metal parts or metal trims.
2. Some plastics are heat-proof only to certain temperatures.
Check carefully!
3. It is possible to use aluminium foil to shield deliate areas of
food (this prevents over-cooking).
4. Metal tins can be used in the combination methods, however
if these are very deep, they will greatly reduce the efficiency,
as metal shields the microwave energy from the food.
Caution:
• There are a number of accessories available on the
market. Before you buy, make sure they are suitable
for microwave use.
• When you put food in the microwave oven, make sure
that food, food supports or covering do not come in
direct contact with any of the internal walls or the ceiling
of the cavity since discolouration may take place.
Before use, the user should check that utensils are suitable for use in microwave ovens.
