Suitable containers for microwave ovens
Roasting bags and tubes can also be used. Roasting tubes should be about 40 cm longer and roasting bags about 20 cm longer than the food being roasted, and carefully tied with string. Turn the ends over and secure them. The bag should be pierced according to the manufacturer’s instructions.
Do not use metal clips, plastic clips containing metal parts or paper ties containing wire.
There is a danger that they will ignite when heated.
Wood
Wooden dishes are not suitable. Moisture contained in the wood evaporates when exposed to microwave energy, causing the wood to dry and crack.
Disposable containers
Only those plastic disposable containers which are specified by the manufacturer as suitable for use in a microwave oven may be used.
Do not leave the oven unattended when reheating or cooking food in disposable containers made of plastic, paper or other inflammable materials.

Testing dishes for their suitability
If in doubt as to whether glass, earthenware or porcelain plates or dishes are suitable for use in a microwave oven, a simple test can be performed:
^Place the item you wish to test in the centre of the oven, fill a suitable glass with water and also place this in the oven.
^Close the door.
^Turn the power selector to 900 watts.
^Enter a time of 30 seconds with the time selector.
^Press START.
At the end of the test, the water in the glass should be warm and the dish cool. If the dish is hot the water cold it would be unwise to use the dish.
If a crackling noise is heard accompanied by sparks during the test, switch the appliance off imme- diately (press button Stop/C twice).
Any crockery which causes this reaction is unsuitable for use in the microwave oven.
If any doubt exists about the suitability of containers, please contact the supplier.
This test cannot be used to check whether items with hollow knobs or handles are suitable for use in a microwave oven.
