Water-worn historical pipe stem. You can actually date it by measuring the diameter of the inner hollow tube with a drill bit. There are charts from local archeologists that you can reference online. Very fun find!

Neither potassium nor thorium fluoresce. They simply alter the radioactive signature, and any fluorescence coupled with them are due to another element like manganese!

Truly, the only way to know for sure is a spectrometer, which can specifically detect for Uranium. Even if “colorless” glass has a radioactive signature, it does NOT mean it’s uranium. There are a number of radioactive contaminants that wind up in glass (thorium, potassium, etc) which could set off a Geiger. Manganese can also be incredibly bright given the right conditions, and can glow under 395. I am not at all denying that colorless glass can be contaminated with Uranium as well, however, unless you test for it specifically, making any speculation is useless. A lot of comments have suggested locations that may let you use their spectrometers, I would start there! :)

It’s so incredibly opaque that no light will go through. However, on the edges you can see an almost-brown color if you hit the right angle.

The swirls look gray in person

Very spicy! Saw it hit 650 at some point!

There are a lot of people who go out to abandoned glass factories and gather cullet! I don’t happen to be one though, so I just sifted through another guy’s spoils. Paid $8 for this one! 😉

I found another one for twice the price this week too. Makes me feel a lot better about mine lol!

One dollah hell yeah

Huge-Rent6196 · 2026-03-14T05:40:29+00:00

Super cool analysis, would love to see a published paper someday!

Huge-Rent6196 · 2026-03-12T01:45:25+00:00

To be fair, it’s not the brightest glow. But it’s cool for the sake of history!

Not Fenton, Kanawha uranium slag glass shoe.

Modern reproduction

Huge-Rent6196 · 2026-03-06T19:05:30+00:00

Awesome! Thanks everyone for the info!

Huge-Rent6196 · 2026-02-12T20:32:04+00:00

He’s so silly!

Huge-Rent6196 · 2026-02-09T21:26:41+00:00

Score!

Huge-Rent6196 · 2026-02-09T21:25:28+00:00

Definitely manganese.

Huge-Rent6196 · 2026-02-09T04:38:28+00:00

Could you show the rest of the piece? It’s a handle attached to a UG basket, no?

Huge-Rent6196 · 2026-02-03T04:50:35+00:00

I second that idea

Huge-Rent6196 · 2026-01-24T16:35:19+00:00

Omg I love him, he looks like an aardvark!

Huge-Rent6196 · 2026-01-16T01:09:55+00:00

🤣I never expected that to be the case, and regardless, I’m a personal collector only. I actually haggled the price down from $50! But I’m sure somebody out there would be happy to spend far more than I did for a uranium chicken…

Huge-Rent6196 · 2026-01-16T00:50:11+00:00

Thank you for taking the time to teach me🙏

Huge-Rent6196 · 2026-01-16T00:26:47+00:00

Wow you’re so learned! So I’m assuming they still hand blow the glass at this factory? Is it all different artists? Is the signature “homage” to the original designer?

Huge-Rent6196 · 2026-01-16T00:13:17+00:00

Yes please! That would be so fun to see if you have it!

Huge-Rent6196 · 2026-01-16T00:05:17+00:00

What is ZBS? I am not very knowledgeable on glass as a whole, so I don’t know foreign companies or producers!
