TESTING COOKWARE, UTENSILS, AND DINNERWARE FOR
MICROWAVE USE
There may be certain non-metallic utensils, cookware, and dinnerware that are
not safe to use for microwaving� If in doubt, you can test the utensil in question by
following the procedure below�
1� Put cookware, utensils, or dinnerware in microwave oven with 1 cup (250 ml) of
water beside it�
2� Cook at 100% cooking power for 1 minute� Note: When performing the test, do not
exceed 1 minute cooking time�
3� Do not use cookware, utensils, or dinnerware if it becomes hot and the water stays
cool�
RECOMMENDED MATERIALS
• Microwave browning dish — Use to brown the exterior of small items such as
steaks, chops, or pancakes� Follow the directions provided with your browning
dish�
• Microwaveable plastic wrap — Use to retain steam� Leave a small opening for some
steam to escape and avoid placing it directly on the food�
• Paper towels and napkins — Use for short-term heating and covering; these absorb
excess moisture and prevent spattering� Do not use recycled paper towels, which
may contain metal and could ignite�
• Glass and glass-ceramic bowls and dishes — Use for heating or cooking�
• Paper plates and cups — Use for short-term heating at low temperatures� Do not
use recycled paper, which may contain metal and could ignite�
• Wax paper — Use as a cover to prevent spattering�
LIMITED USE
Aluminum foil and some metal can be used in the microwave oven� If not used
properly, arcing (a blue flash of light) can occur and cause damage to the
microwave oven.
• Aluminum foil — Use narrow strips of foil to prevent overcooking of exposed areas�
Using too much foil can damage your oven, so be careful� You should keep a
distance of 1 inch (2�54cm) between aluminum foil and cavity�
• Ceramic, porcelain, and stoneware— Use these if they are labeled "Microwave
Safe�" If they are not labeled, test them to make sure they can be used safely�
• Plastic — Use only if labeled "Microwave Safe�" Other plastics can melt�
• Thermometers — Use only those labeled "Microwave Safe�" and follow all
directions� Check the food in several places� Conventional thermometers may be
used on microwave food once the food has been removed from the oven�
