MICROWAVE COOKING TIPS
ENGLISH
Microwave-Safe Cookware
Never use metal or metal-rimmed cookware 
in the microwave oven.
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 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.
