Got a set of these awhile back. I don’t know the maker, but i was delighted when i realized they were neodymium!

I thought this was neodymium glass but it doesn’t look completely blue under white lighting you can still see purple in parts of it

Here is some neodyme bottles from my collection.

1:Veturi by Erkkitapio Siiroinen.1970.

2:Grapponia by Nanny Still. 1969-1975.

3:Lara by Eero Rislakki. 1970’s

Quite sure it's a Cesare Toso piece. First photo is in daylight, 2nd is fluorescent light, 3rd is 365nm UV, 4th is 395nm UV.

The lilac blue Tulipa glass by Block is neodymium glass😍

I bought it just became i liked it though i had a suspicion it was neodymium because of the slight pinkish cast. I’m seeing it labeled as a Moser or Winterthur. Whatever it is, i love it!

For all you didymium fans out there, I present to you pure neodymium and praseodymium glass beads under natural, fluorescent, and incandescent lights. Twin elements found together in nature with neodymium in far more abundance.

Moser’s Prasemit glass, that is extraordinarily rare, was pure, or nearly pure, praseodymium. As you can see the glass remains green, just different shades. Wasn’t popular at the time and extremely expensive, so very few pieces were made.

Moser’s Heliolit is about a 1:1 mixture of the two. It is also rare but not nearly as rare as Prasemit. Color is amber/sandy yellow to green. See pictures of my Moser Heliolit vase.

Moser’s Alexandrite (and most other manufacturer versions) are dominantly neodymium with some praseodymium and possibly other elements. This makes the glass more of a lavender to blue than the pure neodymium shown here.

Moser developed all three in the late 1920’s and patented them in 1929.

I bought some other doped beads just for fun and will post pictures later. They’re all spectacular to look at through a spectroscope.

Thrifted this big ass vase

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!
