13 Things NOT To Put In The Microwave

Microwave ovens—you will find them in almost every residence whether house, condominium, apartment, or college dorm room.  They are also in many places of business, both for use by employees only and for use by the public.  Those for consumer use come in various sizes and power from the small .7 cu. ft. 700 watt dorm room size to those large enough to hold a turkey with a power rating of 1250 watts or higher.  They can be counter top models, installed under a cupboard, or above/part of the stove.

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. Verify this before you put 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.
