I realize this thread is old, but I've had some PS glass rods for years, and never melted the first rod. None of the PS numbers mentioned in this thread match up to the colors of my PS rods, so I don't know what I have - PI, PIG, what?
I have packed up my (200+ lbs. of) glass and my torch for moving, but left this bulk of glass out; it's over 4 lbs. I've googled and checked threads on LE without any clue. If anyone can help identify this, it would be most appreciated. Here's a photo or two.
