Thanks for getting back to me:) That actually confirms my guess, since I've held my fair share of champagne bottles, and the shape hasn't changed much over the centuries. What I'm really curious about is the powdery iridescent film, as I have seen that sort of residue in images of old black...
Sandchip, did you check out the link to the video? There's no black crud, just the goldish film. The curvature of the shard is suggestive of the body of a champagne type bottle, but my bottle experience is limited. My only experience with burned bottles is what we sea glass folks call bonfire...
Thanks for the input, guys. This was a North Carolina Outer Banks beach find. Yes, with a bit of scratching the powdery patina will flake off a bit. This is the first iridescent black I’ve found, if I scrub away the patina will the iridescence remain? Is it cooler to keep the patina, you know...
Your bottle isn't in this report, but I found it helpful in dating my bottle. Maybe there will be some clues... http://bottleinfo.historicbottles.com/pdffiles/OrserBabson1990.pdf
Hey there! I collect sea glass, and especially treasure the black glass I find. Can you tell me anything about the patina on this shard I found a couple of days ago? Benicia?

What causes this film? Is it a sort of Benicia iridescence? I've seen a similar patina on the outside of old black bottles, but in this shard it's on the inside curve. I'd appreciate any insight:)
I'm hoping to identify this partial bottle base. Looks like there are some real black glass connoisseurs posting here, maybe it rings a bell with one of you?
