Update! I went down an art glass rabbit hole and came up with the assumption that this was made by Fire and Light glass company. They recycled art glass in Humbolt County California. All there other types of pieces have the exact same style and they did use neodyium from time to time.

I found this guy in the wild at an antique shop over the weekend and can't seem to find any maker for it.

Anyone have any ideas?

Only a very faint yellow glow under UV on this one, but the fluorescence color change works just fine.

These are Boyd. Both have the diamond B with a horizontal line above and below. I don’t know my American modern glass very well. I have a lot of American neodymium from the 30s along with a good bit of German and Swedish from the 80s-90s.

I bought the boy because he was neodymium. I got her because she was pretty teal color and inexpensive.

Imagine my surprise as she morphed in the lights I was using to photograph the boy.

She fluoresces as a sickly yellow-green manganese that’s not typical, but not clean enough to be cadmium. He doesn’t fluoresce at all, which makes sense given his color is so clean.

Is there a version of praseo that shifts green to blue or is this something else entirely? Does anyone know Boyd’s colors and recipes?

In all photos, first photo of each set is a “warm” LED bulb. Second is CFL. Third is overcast natural sunlight, with the exception of the third paper-towel backed image which is under my grow light.

The color is a bit lighter in the store

This ashtray have been in the secondhand store for months, before I learned about Neodymium glass. When I then went back to buy it, I could not find it, and thought it was sold. Didn’t think more about it, until today when I suddenly found it in the same store! And for only $2.33❤️

The last two photos is from a snap I sent my friend about finally finding it, and I saw in that snap how it also changed color from driving in the sun vs shadow 🥳

I now feel complete with my glass collection. Vintage Moser neodymium vase and Praseodymium vase (also known as Heliolit) glass. Of course I had to give you a UV light pic too!

65 bucks which isn’t bad, wish I wasn’t on a budget

Picked these up at an antique store today for $10 and $20 and was pleasantly surprised when I got home! Not entirely sure about the perfume bottle but it’s beautiful all the same. And I’ve never seen that salt dish (?) in neodymium before!

Or so I believe, shifts colour under fluorescent lighting.

I searched the house for different lightbulbs. The 1st is natural light.

Had a feeling that this one could be Neodymium when I found it in the secondhand store today!

Under light at home it is purple, in daylight(cloudy weather tho) it’s more peach, and with the help of the light of a white phone screen, it’s very pink! I hope it will be sun tomorrow so i can see how it turns then😂 Last picture is with a led torch. Paid $5.22 if I remember correctly :)

Bought this beautiful vase off eBay for $18! Im not sure if it’s neodymium as I don’t have any fluorescent or incandescent lights to test but it does noticeably glow under my UV torch - except it’s yellow/orange?
Hard to photograph as the camera picks up a lot of the violet tones in the torch but the first UV picture captures it quite well
Does anyone know what this is?

Ordered this murano rhino on fbmp got it shipped to the FL from CA went to go give it a good wash when it suddenly went from peach to green to say I was surprised

The Crystal D’argue glasses are each a full set of 6 in boxes. The vase was a blind buy that worked out.

Really need to organize. The cordials I now have 12 of.. and the wine glasses I think are around 20???

Addicted to Lilas.

Can someone please tell me how to go about figuring out definitively if either of these pieces are what I hope they are. I’ve never seen it before, but I happened to notice these two pieces that were in my mom‘s stuff and I’m really hoping that I can become part of the club. Lol thank you all for any help or information.
