13 MICROWAVE COOKING TIPS
Microwave-Safe Cookware
Never use metal or metal trimmed cookware
when using microwave function
Microwaves cannot penetrate metal. They will bounce
off any metal object in the oven and cause arcing, an
alarming phenomenon that resembles lightning. Most
heat resistant non-metallic cookware is safe for use
in your oven. However, some may contain materials
that render it unsuitable as microwave cookware. If
you have any doubts about a particular container,
there's a simple way to find out if it can be used in the
microwave.
Testing Cookware before Use
Place the container in question next to a glass bowl
filled with water inside the oven. Microwave at HIGH
power for 1 minute. If the water heats up but the
container remains cool to the touch, the container is
microwave-safe.
However, if the water does not change temperature
but the container becomes warm, microwaves are
being absorbed by the container and it is not safe
for use in the microwave oven. See the following list
for tips on using common items when microwave
cooking.
Tableware
Many dishes are microwave-safe. If in doubt consult
the manufacturer's literature or perform the microwave
test. Do not put plates with painted decoration in
the oven, as the paint may contain metal and cause
arcing.
Glassware
Glassware that is heat-resistant is microwave-safe.
This includes all brands of oven tempered glass
cookware.
Do not use delicate glassware, such as tumblers or
wine glasses, as these might shatter as when heated.
Plastic Storage Containers
Use these only for quick reheating of food. Do not use
them when cooking food for long periods or at high
power levels, as the hot food will eventually warp or
melt the plastic.
Paper
Paper plates and containers are convenient and
safe to use in the microwave oven, provided that the
cooking time is short and foods to be cooked are low
in fat and moisture. Paper towels are also very useful
for wrapping foods and for lining baking trays in which
greasy foods such as bacon are cooked. In general,
avoid colored paper products as the color may run.
Some recycled paper products may contain impurities
which could cause arcing or fires when used in the
microwave.
Plastic Cooking Bags
Provided they are made specially for cooking, cooking
bags are microwave safe. Remember to make a
slit in the bag so that steam can escape. Never use
ordinary plastic bags for cooking in the microwave
oven, as they will melt and rupture.
Plastic Microwave Cookware
A variety of shapes and sizes of microwave cookware
are available. You may be able to use items you
already have on hand rather than investing in new
kitchen equipment.
Pottery, Stoneware, and Ceramic
Many containers made of these materials are
microwave-safe, but test them before use.
CAUTION
• Some items with high lead or iron content are
not suitable for microwave cooking.
• Cookware should be checked to ensure that it
is suitable for use in the microwave.
