Steph Posted April 11, 2021 Report Share Posted April 11, 2021 UV fluorescence doesn't mean old and doesn't point to any one maker. Uranium glass has been made at least since the 1800's, through the 2000's. Non-uranium glass can also glow under UV light -- that would include the orange glows which could come from manganese. The greens have some different seam shapes mixed in. Most would probably be modern Asian, but maybe not all. The bottom right one looks a bit different. The marble above that one is a darker shade so it could be different. The bottom middle could use another look. Link to comment Share on other sites More sharing options...
