483.0. "Thermos in microwave??" by ARNOLD::WIEGMANN () Fri Jan 09 1987 09:53

    Does anyone know if you can put an open thermos in microwave? No
    metal, just glass and plastic.  We don't have a cafeteria here,
    so I would like to put soup or stew in a thermos, zap it in the
    morning before leaving, and have it be hot for lunch.  I'm don't
    think to clearly in the morning, so want to keep the fuss to a minimum,
    and not have to heat in another container and transfer to thermos,
    etc.
    
    I called the local microwave cooking class lady, and all she said
    was that she wouldn't do it.  She couldn't give a reason why or
    why not, just that she wouldn't.  Superstitous, I guess!

A genuine Thermos brand thermos has a deposited layer of aluminum on the 
glass vessel that holds the food.  That would probably reflect the 
microwaves and prevent the food from heating except through the open 
top.  Other brands of thermos have been known to use styrofoam 
insulation around the vessel, and these would probably heat.  I don't 
know how yours is made, but if the vessel is shiny on the inside, then 
chances are it won't work.  Of course, you could always give it a try 
and let us know how it worked out...

(Watch out if you have an older microwave... they used to be very 
intolerant of ANY metal. If you hear a zap or see little lightning 
bolts, shut it off fast!)

        Even if your thermos doesn't have any metal in it you may still
    have problems.  To test if put the thermos in the microwave empty
    with 1 cup of water in a known microwave safe container.  Then turn
    the oven on high for 1 minute.  If the thermos is hotter than it
    was when you put it in the oven then it isn't microwave safe.
    
        Not all plastics are microwave 'safe'.

    THE OTHER DAY, MY FINE AND BEAUTIFUL BRIDE OF 22 YEARS DECIDED TO
    PACK MY LUNCH FOR LUNCH. SHE WAS GOING TO FIX ME A THERMOS OF SOUP
    AND CHICKEN SANDWICH. BEING THAT SHE IS A COLLEGE GRADUATE, SHE
    CAME UP WITH THE BRIGHT IDEA OF PREWARMING THE THERMOS WITH WATER
    BEFORE SHE PUT THE SOUP IN IT. ANYWAY, TO MAKE A LONG STORY SHORT,
    THE DOG GOT LONELY AND SHE DECIDED TO TALK TO IT AND IN THE MEAN
    TIME THE MICROWAVE WAS WARMING THE WATER AND THE THERMOS ITSELF.
    THE THERMOS WAS MADE OF PLASTIC AND COST ABOUT $9.OO AT THE LOCAL
    DRUG STORE. THE THERMOS NOW RESEMBLES A BLOB OF PLASTIC AND SHE
    AND I AREN'T ON SPEAKING TERMS FOR CALLING HER STUPID...SO IF I
    WERE YOU AND YOU ARE MARRIED, EITHER DON'T TRY IT AND DON'T CALL
    HER STUPID...MIKE IN PHOENIX

    Re: .3 - Meltdown, What a scream!  I guess I'll try it some Saturday
    he's working.  Although, he's so attached to his #@*&! dog, he'd
    probably just be glad that I talked to it at all (he doesn't understand
    allergies!)
