Metal
Small metal skewers and aluminium trays (of prepackaged food)
may be used. However, they must be small in proportion to
the food. Aluminium containers, for example, must be filled to
at least

with food. It is recommendable to transfer the
food into microwave-safe containers.
When using aluminium trays or other metal utensils, they must
be placed at least 2.0 cm away from the cavity walls. Otherwise
the cavity walls may be damaged by sparking.
Do not use any utensils with metal-plating, metal parts or metal
projections like screws, ribbons, or handles.
TESTING UTENSILS
Perform the following test if you are unsure whether a certain
utensil is microwave-safe: Place the utensil into the oven,
put a glass containing about 150 ml of water on or beside
the utensil, and operate the microwave oven on 1800 W for
1 to 2 minutes. If it is cool or lukewarm to the touch, the
utensil is suitable for microwave use. Do not perform this
test on plastic dishes because the plastic might melt.
INFORMATION ABOUT POWER LEVEL
1800-1300 W (POWER LEVEL 13-8):
The high power is perfect for warming up or regenerating food.
You can also use it to make food boil e.g. water and then cook
further with lower power. (e.g. for rice or noodles)
1200-750 W (POWER LEVEL 7-4):
For longer cooking times and compact types of food.
500 W (POWER LEVEL 3):
For delicate cooking. Also after cooking to simmer or for noodles
and rice.
340-150 W (POWER LEVEL 2-1):
The low power level is mainly for defrosting. You can also use it
for cooking of very delicate menus like cheese sauce.
Basically it is recommendable to cover the food for cooking or
reheating. Additionally you can sprinkle some water over the food
(you can also use salted water or even bouillon).
The water steam keeps the food moist and it also helps to make
the cooking faster.
Microwaves set the water molecules contained in the food
vibrating. The resulting friction generates heat that can be used
to defrost or cook the food.

SUITABLE UTENSILS
Glass, Glass-ceramics and Porcelain
Heat-resistant utensils made of glass, glass-ceramic or
porcelain are suitable. However, the utensils must not contain
metals (e.g., lead crystal) or be metal-plated (e.g., gold rim,
cobalt blue).
Glass, Porcelain, Ceramics
Plastics, paper etc.
Ceramics
are usually suitable but they must be enamelled. When using
utensils that are not enamelled, moisture can be absorbed by
the material and heat it up. This can cause the material to crack.
Plastics and Paper Dishes
Heat-resistant and microwave-proof plastic utensils or paper dishes
are suitable for defrosting, heating and cooking. Please follow the
manufacturer's instructions.
Microwave Plastic Wrap
or heat-resistant wrap is suitable for covering and wrapping food.
Please follow the manufacturer’s instructions.
Roasting Bags
can be used in microwave ovens. Do not close the bags with
a metal clip because the clip may cause the bag film to melt.
Close the bag with string and pierce it several times with a fork.
Films that are not heat-resistant, e.g., films to retain product
freshness are not recommended for use in microwave ovens.
Metals
should not, as a rule, be used in microwave ovens because
microwaves cannot penetrate metals and reach the food inside.
There are, however, some exceptions: Small strips of aluminium
foil can be used to cover parts to prevent them from defrosting
or cooking too fast (e.g., chicken wings).
