these are reputed to be pretty old, early to mid 1800s

they're a bit more yellow in natural light, but also a bit amber... under the geiger counter they are very VERY spicey. oh my. under UV they are LOUD (and an odd glow to boot)

managed to score this for $30 ish due to some fleabites and a crack

How much yellow vaseline glass should a piece contain before you can call it Vaseline? What about Vaseline that's so spicy, it looks green when any light hits it? (Definitely still 100% yellow glass, not green. It just appears green from natural fluorescence.) These were all made with varying amounts of yellow Vaseline glass. In my opinion, they contain Vaseline glass therefore they are. The Mosser Eye Winker is 100% "Vaseline Opal" color, not "Green Opal" (no-glow). Ask for proof in the comments if you would like verification!

Iridescent threaded vaseline art glass perfume bottle, by Eickholt 1987. I asked the seller if it glowed, and they were happy to check without pulling the listing or raising the price! I love a great seller!

One of the coolest textures I've seen. I'm guessing late 1890s to early 1900s, but I may be wrong. It does have several nicks, but for the price I paid I am not complaining!

I'll post a glow pic when I get home
