In one booth, an artist was selling fused jewelry which was mostly glued to the findings--pendant bails, link bracelets, earring posts. Towards the back of the booth there were pendants set in sterling that were priced just barely higher than the glued-on ones. Knowing the time and materials cost involved in making a bezel, I suspected they were imports that were bought and resold more or less as-is.
In another booth, just as I walked in, the lampworked beadmaker there was explaining fusing to a customer. It was a pretty disdainful assessment: "oh, fusers, well, they just put pieces of sheet glass together and fire it--they could make like 100 earrings--just put it in the kiln, come back a couple hours later and it's all done." This was said, with the implication that lampworking was far superior, because it took more time and skill, and the artist and customer had a little snicker over it.
And God help me, I didn't say anything.

I'm also wondering how much of this artist behavior goes on in the mediums I'm less familiar with and wouldn't know the difference.
What kind of approach is best? Should I have tried to sniff out the origins of the bezel set pendants by asking a few pointed technical questions to their seller? And if there was any hesitation or inaccuracy to the answers, yell, "AHA! I knew it!" Should I have lashed back at the lampworker?
Grrr...I hate this morning-after regret. Maybe I should just try to see if the bookstore carries Chutzpah for Dummies...
