Utensil Guide
Microwaves are a form of high frequency electromagnetic
waves (app. 12 cm wave length) similar to those used by a
radio.
Electricity is converted into microwave energy by the
magnetron tube. The microwaves travel from the magnetron
tube to the oven cavity where they are reflected, transmitted
or absorbed.
Reflection
Microwaves are reflected by metal
just as a ball is bounced off a wall.
A combination of stationary (interior
walls) and rotating metal (turntable
or stirrer fan) helps assure that the
microwaves are well distributed
within the oven cavity produce even
cooking.
Transmission
Microwaves pass through some
materials such as paper, glass and
plastic much like sunlight shining
through a window. Because these
substances do not absorb or reflect
the microwave energy, they are
ideal materials for microwave oven
cooking containers.
Absorption
Microwaves are absorbed by food.
They penetrate to a depth of about
2-4 cm. Microwave energy excites
the molecules in the food
(especially water, fat and sugar
molecules), and causes them to
vibrate very quickly.
The vibration causes friction and
heat is produced. In large foods,
the heat which is produced by friction is conducted to the
center to finish cooking the food.

*Caution
•
Plastics:
Plastic dishes, cups and some freezer containers should be used with care in a microwave oven.
Choose plastic containers carefully, as some plastic containers may become soft, melt and scorch.
•
Paper Products and Freezer Wrap:
Waxed paper, paper plates, cups and napkins should not be used for heating or cooking food by Combination and Grill.
Freezer wrap should not be used as it is not heat resistant and bake paper may be safely used for short periods of time for
covering or lining.
