...but go through glass or porcelain...
...and are absorbed by foods.
Fire risk!
Never put your metal or metal
coated containers into the mi-
crowave oven.
• Microwaves cannot penetrate metal. Mi-
crowaves will reflect off any metal objects
in the oven causing dangerous electric
arcing. Most heatproof non-metallic con-
tainers are suitable for use in a microwave
oven. But some containers may include in-
appropriate material for use in a mi-
crowave oven. To determine if a container
is suitable for a microwave, you may use
the following test:
• Place the empty container you want to
test and another container filled with water
inside the oven.
• Run the oven at high power for one
minute. If the water is warm and the con-
tainer you are testing is cold, then the con-
tainer is suitable for the microwave.
• On the other hand, if the water is cold and
the container next to it gets hot, then mi-
crowaves have been absorbed by the
container and this container is not suitable
for microwave use.
Glass containers
• Do not use thin glass or lead crystal con-
tainers. Heatproof containers are suitable
for microwave ovens. But do not use fra-
gile glass containers like water and wine
glasses, materials of which can be broken
when heated, in the microwave oven.
Plastic containers
• Do not hold containers and dishes made
of plastic or melamine in the microwave for
too long; that goes for the plastic bags
used to hold frozen food as well. The
reason behind that is, the heat of a hot
meal will eventually melt and deform the
material. Use these types of material in the
microwave for just a limited amount of
time.
Cooking bags
• Cooking bags can be used in the mi-
crowave oven as long as they are de-
signed for cooking. Do not forget to pierce
the bags to allow the steam inside to es-
cape. Do not use regular plastic bags for
cooking as they will melt and open.
Paper
• Do not use any type of paper for pro-
longed cooking. This will cause the paper
to burst into flames. Paper plates are only
good for oily or dry food that requires
small amount of time to cook.
• Do not use recycled paper. These papers
may have molecules that may cause
arches.
Wooden and wicker containers
• Large wooden containers should not be
used, as the microwave causes the wood
structure to dry out and become brittle.
Porcelain containers
• Generally, containers made of these types
of material are good to use inside mi-
crowave ovens, but you need to test it to
be sure.
Metal containers
• Metal containers reflect microwaves away
from food. So do not use them.
Certain cookware with high iron and
lead content is not suitable for use in
microwave ovens. Be sure to check
if your containers are microwave-
safe.
