Jack 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. Dave |

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. -lauri |

I first started fusing with my little microwave kiln, got it maybe 20/25
years ago? (How long have microwaves been around?) any way, it was fun to play with and i still have one for museum puposes but there was no control and i do not recomend trying to learn on it. m "Lauri Levanto" wrote in message ...

Where can you get to 1200 degrees in a few minutes? The reason they were pulled off the market was potenial contamination lawsuits from using it in a microwave that was also used for food. -- JK Sinrod www.SinrodStudios.com www.MyConeyIslandMemories.com |

Sleazier lawyers over here I'm thinking? Is that some kind of pun ? or oxymoron ?? Ive melted doing a casting in a microwave. The trick is in the annealling. It does melt a handfull of glass in a brick/frax mold/enclosure. Used no metal. |
