YES
Testing dishes for suitability - for Microwave cooking only.
When unsure that a cooking container is
suitable for use in your microwave, check by
using the following test:
1. Fill a microwave safe measuring jug with
300ml of cold water.
2. Place this bowl next to the container you
want to test, on the glass tray. If the
container to be tested is very wide, place
the measuring bowl inside it.
3. Heat on MAX for 1 minute.
NO when cooking with microwaves
YES when cooking using the grill
NO when using Combination cooking
Result
If the container is suitable for microwaves, it
will stay the same temperature whilst the water
will be warm. If the container seems hot, that
means it absorbs microwave energy.
Therefore you cannot use it in Microwave
mode.
Note: This test cannot be used for plastic
containers or containers which are completely
enamelled, such as Le Creuset ® cookware,
as these dishes have cast iron underneath the
layers of enamel.
