Default Microwave Kilns

Seems they were around some years back. Anybody know anything about them?

I seem to remember some years back - maybe 10 or more - that I saw a
promotion at a conference for a method to fire pottery in a microwave oven.
It turned out to be a refractory container coated inside with some metallic
substance which could attain a chamber temperature of 1000 + degrees C when
placed in a microwave oven on high. Only trouble was that the container for
a domestic microwave was tiny and almost useless - you would need an
industrial strength and sized microwave to provide enough power to heat a
decent sized chamber, which would probably cost more than a kiln anyway.

I suspect the idea died a deserving death.

In addition to that,
what my friend have experimented
there is very little if any control of the temperature.
She said it had to make a pair of earrings identical.

One possible use might be PMC clay.
With that price for material, miniature size is a blessing.
