Checking Your Cooking Utensils - Hitachi HIT BG17SS Instruction Booklet

Microwave ovens cook food using microwave energy that is
similar to naturally occurring radio waves. Normally, these
"waves" would fade as they disappeared into the atmosphere,
but in a microwave oven they are concentrated onto food
causing it to heat up.
Microwave energy can not pass through metal – so it can not
escape from inside your microwave oven – but it can pass
through materials like glass, porcelain, plastic, and paper.
These are the things used to make microwave-safe cooking
equipment.
Microwave-safe cooking equipment will still get hot as the
food it contains heats up.

Checking your cooking utensils

Most heat-resistant, non-metallic cooking utensils are safe to use in your
microwave. If you are not sure you can use a utensil in your microwave,
follow this simple test:
1 Make sure that the grill is positioned in the upwards position to
the top of the microwave (Do not use your hands to touch the grill
as it may already be hot).
2 Put the utensil into the oven next to a cup of water – use a cup
that you know is microwave-safe. Close the door
3 Turn the microwave oven on for 30 seconds only.
4 At the end of the time, carefully check to see if the water has
warmed up. If the water has not warmed up but the utensil has, the
utensil is not microwave-safe and should not be used in the oven.
The microwave energy focuses on the moisture in the
food causing lots of tiny vibrations. The vibrations get so
great that the moisture – and the food – heat up.

Safety
Never use equipment
made of metal, except
foil in your microwave
oven.
The microwave energy
can not pass through the
metal so it bounces off
and sparks against the
inside of the oven.
Stop the microwave straight
away if any equipment does
cause sparks.
Remember that some crockery
has a metal trim around the
edge. Even this trim can cause
sparks.
Safety
Never use scratched,
cracked or damaged
glass in a microwave.
Damaged glass can
explode.
