USE
Ovenproof Glass
• Glass treated for use in high-intensity heat
includes utility dishes, bread dishes, pie plates, cake
plates, liquid measuring cups, casseroles, and bowls
without metallic trim.
China
• Bowls, cups, serving plates, and platters without
metallic trim can be used in your oven.
Plastic
• When using plastic wrap as a cover, make sure that
the dish is deep enough so the plastic wrap does not
touch the food. As the food heats, it may melt the
plastic wrap wherever the wrap touches the food.
• Place plastic wrap loosely over the top of the dish
and secure it by pressing the wrap to the sides of
the dish.
• Vent by turning back one corner of the plastic wrap.
This will allow excess steam to escape.
• Use plastic dishes, cups, semi-rigid freezer
containers, and plastic bags only for short time
cooking. Use these with care because the
plastic may soften from the heat of the food.
Paper
• Microwave-safe paper towels, waxed paper, paper
napkins, and paper plates with no metallic trim or
design can be used in your oven.
• Refer to the manufacturer’s label for use of any
paper product in the microwave oven.
DO NOT USE
Metal Utensil
• Metal shields food from microwave energy and
produces uneven cooking. Avoid metal skewers,
thermometers, or foil trays.
• Metal utensils can cause arcing, which is a
discharge of electric current. Arcing can damage
your microwave oven.
Metal Decoration
• Do not use metal-trimmed or metal-banded
dinnerware, casserole dishes, etc.
Centura™ Tableware
• The Corning Company recommends that you
do not use Centura tableware and some Corelle™
closed-handle cups for microwave
cooking.
Aluminum Foil
• Avoid large sheets of aluminum foil because
they hinder cooking and may cause arcing.
• Use small pieces of foil to shield poultry legs
and wings.
• Keep all aluminum foil at least 1 inch from the walls
and door of the oven.
Wood
• Wooden bowls, boards, and baskets will dry out and
may split or crack when you use them in the
microwave oven.
Tightly Closed Containers
• Tightly closed cookware can explode. Be sure
to leave an opening for steam to escape from
covered cookware.
Brown Paper
• Avoid using brown paper bags. They absorb
heat and could burn.
Metal Twist Ties
• Always remove metal twist ties as they can become
hot and cause a fire.
COOKWARE GUIDE
Most heat-resistant, non-metallic cookware is safe for use in your microwave oven. However, to test cookware
before using, follow these steps:
1. Place the empty cookware in the microwave oven.
2. Measure 1 cup of water in a glass measuring cup and place it in the oven beside the cookware.
3. Microwave on 100% power for 1 minute. If the dish is warm, it should not be used for microwave cooking.
