Fire hazard. Containers which
are not suitable for use in
microwave ovens can be badly
damaged and can cause damage
to the appliance if used.
Material and shape
The material and shape of containers
used affect cooking results and
durations. Heat distribution is more
even in round and oval shaped flat
containers than in rectangular
containers, providing better results.
Containers and lids with hollow
handles or knobs in which moisture
can collect are unsuitable, unless
the hollowed handles are
adequately vented.
Without vent holes, pressure can
build up, causing the container to
crack or shatter with the danger of
injury.
Metal
Metal containers, aluminium foil,
metal cutlery, and china with
metallic decoration such as gold
rims or cobalt blue must not be used
with microwave mode.
Metal reflects microwaves and
obstructs the cooking process.
Also, avoid using plastic pots where
the foil lid has not been completely
removed.
