Good to know. Do you know the username of any, that way I can try PMing one of them real quick.We do have some glass blowers on this forum that you could maybe check with. Can you feel the abrasions or are they inside of the glass? If you can feel the abrasions maybe use a rough sponge and carefully work it out?
That's the tricky part about it, it's so fucking hard to tell if it's actually on the glass or inside. I can tell that they're on a certain side, but I can't tell if it's just below the surface. I soaked it in 99ISO and vinegar (in case it was rust), it helped some but not completely. I'd be one thing if I knew it was embedded into the glass, but when I first cleaned it the cloth had a reddish-brown smudge from whatever it is, so some of it was not trapped within the glass. I tried scraping it lightly with a wire brush pipe cleaner, Q-tips, and one of my pointed dab tools to no avail.
