The first microwave oven was invented after World War II
from radar technology developed during the war. The Radarange, as it was
called, was first sold in 1946 but was prohibitively large and much too
expensive for all but the largest of commercial applications. The home-use microwave oven was introduced in
1955, but was still too large and expensive for general home use. The practical
countertop home-use microwave oven was introduced in 1967. For those of us
'older' folks, we quickly adapted to their use.
The younger among us grew up with them.
This list of 13 items relates to specific dangers from
trying to heat certain items in your microwave.
I imagine we've all learned the hard
way (no pun intended) what happens when we try to microwave bread-type products
rather than heating them some other way.
That one is not dangerous, but it dries out the food and when the items
start to cool they become too hard to eat. This can be somewhat circumvented by
wrapping the food item (i.e. sandwich or whatever includes a bread type food)
in a slightly damp paper towel.
1) Aluminum Foil—we all know that one, it
literally catches on fire.
2) Stainless Steel—we all know not to put
our metal pots and pans in the microwave.
That also includes our stainless steel travel coffee mugs. In addition to possible harm to the
microwave, the metal blocks the waves so it won't heat your cold coffee anyway.
3) Plastic Storage Containers—these contain
chemicals that could be toxic, or at the least alter the taste of the food you
are reheating. Now there are plastic containers listed as being microwave safe. Make sure you verify this before putting it in the microwave.
4) Chinese Take-Out Cartons—the metal
handles on the carton are dangerous and the cartons themselves contain plastic.
5) Styrofoam—this is plastic.
6) Raisins—these smoke when heated in a
microwave.
7) Grapes—if raisins are bad, it follows
that the fruit that gives us raisins are also a microwave no-no. The grapes will catch fire.
8) Plastic Bags—the type the store uses to
bag your purchases in addition to the more heavy-duty storage type. These are toxic and can catch fire.
9) Brown Paper Bags—these are as dangerous
in the microwave as the plastic bags the stores use.
10) Eggs—if in the shell, they will explode.
11) Dried Hot Peppers—chemicals are released.
12) Sauce—without a lid, it will splatter all
over the inside of the oven and create a messy cleanup.
13) Nothing—to run an empty microwave can
harm the appliance as there's nothing there containing water molecules for it
to absorb.
