I was trying to make some popcorn balls. Two of the ingredients were
sugar and honey. One of these two heats to greater than the melting
point of plastic.


I have nuked food many times without burning a hole in the bowl. Not
so this time.

I have found that three things will melt plastic in the microwave:

Tomatoes
Sugar
Most oils/fats (butter etc.)

The oils are not as much of a problem as Tomato or Sugar,

I've learned to use glass for both of those two!

oops! <lol>
I've always cooked rice in the corningware, covered, so never
experienced that. ;-)

What plastic? Plastics can have melting points from 180 to over 300
degrees.
Sugar and honey will go over 300 degrees. IIRC, sugar caramelizes at 338.
That would easily melt a low grade plastic.

Even the Tupperware Crystalwave line which is marketed for 'reheating in
microwave' will pit when there is a high sugar (or fat) content in the food
being reheated unless you either reheat on low power or stir frequently to
prevent hot spots.

Another important factor is whether it is liquid or solid. A liquid is
much less likely to cause melting because the convection currents tend
to move the hotter material around. Solids, because they cannot move,
are far more likely to create local hot spots and burn, scortch, or
melt.

anything
1) that will reach the roughly 400 degrees at which plastic melts and
2) has enough conductivity to deliver enough mass of heat to the bowl and
3) is big enough to hold the heat above bowl melting before the bowl plastic
can dissipate it

- water goes no higher than 212 F or so: e.g., soups, veggies, etc don't
get hot enough to melt plastic

- oil goes over 400, so it can melt plastic: e.g., some meats are oily, and
their fat will melt plastic.

- a small spot of oil does not have enough mass to get enough heat in it
fast enough that the bowl can't get spread that heat out quick enough not to
melt at the spot. A larger amount of oil can get enough heat from the oven
so that the bowl can't handle it, and melts the plastic

At the point of being a smarta**, I always use Pyrex bowls or microwave safe
ceramic-type bowls in the microwave. The only time I use plastic is if I'm
reheating soup (like at the office where I have to transport it with a
tight-fitting lid). At home I tend to use the (non-plastic) bowl from which
I plan to eat.
