of the process. The aluminium foil must
not touch the interior walls of the oven.
Make sure that the aluminium foil is
at least 2 cm from the oven walls at
all times. It must not touch the walls.
– Metal meat skewers or clamps:
Metal skewers and clamps should only
be used if they are very small in com-
parison to the size of the cut of meat.
Glassware
Heat-resistant glass or ceramic glass
are ideal for use in the microwave oven.
Crystal glass contains lead which
could cause the glass to crack.
Glass dishes with a milled rim are
subject to the same risk. Both are
unsuitable for use.
Porcelain (chinaware)
Porcelain (chinaware) is a suitable ma-
terial.
Do not use porcelain with gold or sil-
ver edging or items with hollow
knobs or handles, as insufficient
ventilation may cause pressure.
Earthenware
Decorated earthenware is only suit-
able if the decoration is beneath an
all-over glaze. Earthenware can get
very hot, and may crack.
Glazes and colours
Some glazes and colours contain
metal.
This makes them unsuitable for use in a
microwave oven.
Plastics
Plastic containers must only be
used for microwave mode alone
and not in normal oven mode. Plas-
tics must be heat-resistant to a mini-
mum of 180°C.
Otherwise the plastic may melt and
fuse with the food.
Special plastic utensils, designed for
use in microwave ovens are available
from most department and hardware
stores. Melamine ware is not suitable
as it absorbs energy and heats up.
When purchasing plasticware, make
sure that it is suitable for use in a micro-
wave oven.
Disposable containers, such as trays
made from polystyrene, can only be
used for very short timed warming and
re-heating of food.
Plastic boiling bags can be used for
cooking and re-heating. They
should be pierced beforehand so
that steam can escape.
This prevents a build-up of pressure
and reduces the risk of the bag bur-
sting.
