To test a container / utensil for safe microwave oven use: 
Add 1 cup of cool water to a heat resistant glass jug and place it in the microwave oven 
alongside the empty container/utensil to be tested; heat for one (1) minute at maximum 
power.
If the container/utensil you are testing is microwave oven safe (transparent to microwave 
energy) it should remain comfortably cool, the water in the glass jug should be hot. If the 
container/utensil being tested is hot, it has absorbed some microwave energy and 
should NOT be used.
This test is not applicable for plastic items. Check the markings on plastic items to 
ensure they are microwave safe. 
CAUTION: Personal Injury Hazard. Use an oven mitt or tea towel when handling 
containers and utensils that have been heated in the microwave.
