Notes on containers
Suitable containers
Microwaves penetrate porcelain,
●
china, glass, cardboard and plastic, so
containers made from these materials
are suitable for use in the microwave
oven.
Porcelain can generally be used without
●
a problem, however, some dishes have
a metallic glaze or decoration and
these are not suitable for the
microwave oven.
Painted stoneware can be used
●
provided the pattern is covered with a
glaze. Stoneware can become very
hot.
Heat-proof glassware and ceramic are
●
particularly suitable.
Plastic containers must be able to
●
withstand a cooking temperature of at
least 110°C, otherwise they will distort.
Polystyrene containers suitable for
short reheating periods can be used,
but only at a low temperature.
Roasting bags can be used provided
●
they are closed with string rather
than metal clips. Never use fastenings
that contain metal.
The material and shape of a container
●
affect the cooking and reheating
time. Round and oval dishes are good.
Food heats up more evenly in these
shapes than in a container with
corners.

Unsuitable containers
Metal containers, aluminium foil and
●
cutlery should never be placed in the
microwave oven, as metal reflects the
microwaves and they cannot penetrate
the food effectively. Food inside a
closed metal container or wrapped in
foil will not heat up at all.
Never use dishes with a metallic trim
●
such as gilt or cobalt blue. The metal
content will reflect the microwaves
and create sparks.
Crystal is unsuitable as it contains
●
lead. Handblown crystal should also
be avoided as the microscopic bubbles
in it will cause it to shatter. The same
applies to glassware with fluted or
curved edges.
Wooden dishes cannot be used in the
●
microwave oven as the water in the
wood turns to steam during cooking,
causing the wood to dry out and split.
