Wood
Wooden recipients should not be used in the
microwave. Wood contains water which evaporates
and may cause the recipient to crack.
Recipient Test
If in doubt about the use of glass, glazed ceramic or
porcelain dishes in the microwave oven, do the
following test:
1. Place the empty dish and a glass of water inside
the microwave oven.
2. Close the door.
3. Select the microwave function at maximum
power.
4. Adjust the timer to 1 minute.

If during this test you hear any noise along with

Any kind of cookware that has this kind of behaviour
or is very hot when removed from the oven should

EXCEPTIONS:
Glazed ceramic dish recipients contain many water
molecules and heat a lot, but can be used in the
microwave oven.
If in doubt, contact the supplier of the cookware, and
make sure that they are appropriate for microwaves.
Lids
The use of glass lids, plastic lids or plastic film is
advisable because:
1. They prevent the release of excessive vapours
especially when cooking for longer periods.
2. They increase the speed of heating food.
3. They prevent the food from drying up.
4. They prevent the loss of the food aroma.
The lids should have holes to avoid pressure. Plastic
film should be perforated.
Baby bottles, baby food jars and other similar
recipients should be warmed up without lids as they
can burst.
