The importance of the 'Microwave' Cooking question is not whether the food
someone cooks is effected by heat...of course it is, and that is 'why'
people 'COOK' foods, TO 'effect' them Chemically and otherwise, by duration
of 'Heat'.

The question of 'Microwaves' in cooking Foods, concerns the particulars of
the kinds of effects and kinds of 'Chemistry' the kind of 'heat' it is, wil=
l
cause in the food...and hence, 'in' the Organism eating the food so heated.


Leaving aside other liabilities of persons or other Organisms being
themselves 'irradiated' or exposed to Microwaves when being near the
operating 'Oven' or other device.

Rebecca, I think it is the most likely conclusion of folks who have
some science background. I am very careful about what I eat. As
Linnus Pauling once said, the single thing we can do that can have the
greatest effect on our good health is to drink plenty of pure water.

Here are some short explanations of what happens in cooking:

The most common chemical reaction in cooking, the Maillard reaction:

small-scale, seemingly constricted form that challenges the artist to
go beyond mere technical virtuosity and find an approach that both
satisfies and transcends the conventions." -- Rob Sliberman

Hi Heather,
I have a lot of tenmoku glazed pots - never had a problem in a microwave
oven with any of them - I'd like to see the recipe of your glaze so I can
compare them. Maybe I can make an adjustment to make it behave.

Best to test stuff in a microwave with another bowl or something with some
water in it - taking the temperature of the water as you increase the
duration and power will help answer questions and protect your oven.
