Years ago, I was given some large, inexpensive coffee mugs. They were
basically white with different color dots. Only the green dots became
hot in the microwave. Based on the blister I got on my thumb from
the green dot on the handle, I'd guess that dot got up well over the
boiling point of water. Darn hot. Looked like a chrome green glaze to
me.

The issues are a world apart. Teflon is a complex chemical, created
through industrial processes many of which are trade secrets. Some
of the precursor chemicals are quite dangerous indeed. Are there
residue issues? Yes, but we can't tell how serious they are.
And teflon is getting everywhere in the food chain, so you're probably
getting some intake from eating animals, vegetables, etc. contaminated
with it. In defense of the teflon industry, there's been lots of testing and
so far no serious side effects have been spotted in the general public,
though there have been some alarming things among workers in the
teflon factories. Whether you choose to use teflon or not, you are
certainly dealing with a product and it can, in high concentrations,
be harmful.

Microwave ovens are RF emitters -- the tubes are specially made to
radiate on the frequency of water's H-O bonds. The ovens are pretty
well sealed, and microwaves are reflected by metals -- the walls of a
microwave oven are metals selected to guarantee that reflection.

RF is a class of radiation, but it is not ionizing radiation. Radioactive
radiation (alpha, beta, gamma and neutrons) is, in varying degrees,
dangerous, and it's ionizing. X-rays are dangerous; they're ionizing.
Ionizing radiation is that which has enough energy to strip electrons
from atoms, creating charged particles. It's the action of the
charged particle that causes the harm.

Non-ionizing radiation includes visible light, radio/tv transmissions,
infrared, ultraviolet, and ELF (which you only really get from high-tension
lines and those induction furnaces found in some factories). They
are consequently generally conceded to be not dangerous. There is,
however, a way to protect yourself from any dangers that may exist
and have not been discovered -- stand a good distance from the
microwave while it's on. The intensity decreases with the cube of
the distance, so it's probably not hard to get to a safe range even
if there is an unsafe element to the oven.

And, because the stuff heated up in the oven is hotter, but not
possessed of charged particles, it's essentially no different from
the same material heated up a different way.

Hope that's not too confused to be understood --

I tend to get a bit silly late at night, so please bear with.

If someone had my bowels in a microwave for more than a little time, I
wouldn`t be very happy either.

Hi Sam,

I don't think there is a danger except if the seal around the door is
leaking - can cook you a bit if you are standing there - a good reason to
think twice about having them mounted at eye level.

If you do you should check to see if the seal is good once in a while.
