CONTAINER TEST
TO TEST A CONTAINER FOR SAFE MICROWAVE OVEN USE: Fill a microwave safe cup with cool water
and place it in the microwave oven alongside the empty container to be tested; heat one (1) minute at P10
(HIGH). If the container is microwave oven safe (transparent to microwave energy), the empty container
should remain comfortably cool and the water should be hot. If the container is hot, it has absorbed some
microwave energy and should NOT be used. This test cannot be used for plastic containers.
