I took a class on PMC and here's what I learned: Regular sterling silver is .925 pure with (I think) nickel constituting the balance, and that's what causes black spots or discoloration on glass. PMC Clay is .999 pure. I've accidentally used both in my kiln (oops :evil: ) and the sterling does cause...

I've got both the circle cutter and cutters mate, and love them. I would recommend both to anyone with problems with hands, arms, shoulders (or is otherwise circle-impaired) Judi
Hello gang of glass -
My small kiln's temperature controller somehow got all whacked out and no longer gives me an accurate temp read. Any ideas how to reset / readjust? Unfortunately, I've lost all the literature that came with it.
Thanks! - Judi
Does anyone out there know of a good source for silver art clay? There's a low-temp version that fuses at glass-fusing temps - but I'm finding all sources to be around the same price, $14 - $19 for 10 gr. Any ideas?
