• If in doubt about the use of glass, glazed ceramic or
porcelain dishes in the microwave oven, do the
following test:
- Place the empty dish and a glass of water inside the
microwave oven;
- Close the door;
- Set the Power Level Selector at maximum power;
- Adjust the timer to 1 minute;
! If during this test you hear any noise along with
sparks, turn off the oven immediately.
• Any kind of cookware that has this kind of behaviour
or is very hot when removed from the oven should not
be used in the microwave oven.
! 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.
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.
