Roasting bags and tubes can 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 or wire ties,
even if bound by paper.
There is a danger that they will ignite
when heated.
Wood
Wooden dishes are not suitable.
Moisture contained in the wood evapo-
rates when exposed to microwave en-
ergy, causing the wood to dry and
crack.
Disposable containers
Only those plastic disposable contain
-
ers which are specified by the manu
-
facturer as suitable for use in a micro
-
wave oven may be used.
Do not leave the oven unattended
when reheating or cooking food in
disposable containers made of plas
-
tic, paper or other inflammable ma
-
terials.
Disposable containers are not always
recyclable or bio-degradable.
Testing dishes for their
suitability
If in doubt as to whether glass, earthen
-
ware 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
small container should be warm but the
dish cool. If the dish is very hot and the
water is cold, it would be unwise to use
the dish.
If a crackling noise is heard accom-
panied by sparks during the test,
switch the appliance off immediately
(press button Stop/C twice).
Any crockery which causes this reac
-
tion is unsuitable for use in the micro
-
wave oven.
If any doubt exists about the suitabil
-
ity of containers, please contact the
supplier.
This test cannot be used to check
whether items with hollow knobs or han
-
dles are suitable for use in a microwave
oven.
