Plutonianfire Posted April 15, 2023 Report Share Posted April 15, 2023 Please see photos of three similar dark blue swirls. Two fluoresce green and one fluoresces light blue. I wonder if that can help with identification? Link to comment Share on other sites More sharing options...
Steph Posted April 16, 2023 Report Share Posted April 16, 2023 More views on the top left please. I would like to see if that one is a Peltier Rainbo. I'm thinking West Virginia swirl on the top right. No guess at this time on the third marble. Swirl? Slag? Rainbo? No guess yet. Among the WV swirls there is an Alley which is called a Pistachio which is expected to glow under blacklight, but that's a green based marble. And there's a Jackson swirl which is dark blue with a swirl that looks unremarkable, but the swirl can be fluorescent. So those are two examples where it's helpful to know what they do under blacklight. In general though, it's not a factor in identifications. Here's my Jackson which illustrates the above. The understated ribbon was made with fluorescent Vitrolite cullet. Link to comment Share on other sites More sharing options...

Chad G. Posted April 16, 2023 Report Share Posted April 16, 2023 West Virginia Swirl, not positive on manufacture IMO Slag, best guess would be Akro IMO Leaning Peltier Rainbo on this one Link to comment Share on other sites More sharing options...

Steph Posted April 16, 2023 Report Share Posted April 16, 2023 I'm at WV Swirl, Pelt Rainbo, and still undecided. On #3, I'll nod at the Akro slag possibility yet will add Japanese Transitional for consideration. P.s., I'm not overlooking what appears to be a big chunk of furnace brick. That's worth a mention in case no one has said it before. Link to comment Share on other sites More sharing options...
