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.
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.

LIMITED USE
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 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.
Not Recommended
Glass jars and bottles
— Regular glass is too thin to be used in a microwave. It can shatter and cause
damage and injury.
Paper bags
— These are a fire hazard, except for popcorn bags that are designed for microwave use.
Styrofoam plates and cups
— These can melt and leave an unhealthy residue on food.
Plastic storage and food containers
— Containers such as margarine tubs can melt in the microwave.
Metal utensils — These can damage your oven. Remove all metal before cooking.
Note:
Should you wish to check if a dish is safe for microwaving, place the empty dish in the oven and
microwave on HIGH for 30 seconds. A dish which becomes very hot should not be used.
