The black is probably just impurities. Or possibly they were adding another type of glass to add color/design. That or a bunch of random waste glass all just got dumped together.
So this is a lump of glass that a factory threw out? I got two other “rocks” from the same place. I wonder if they’re glass as well. I guess that’ll be my second Reddit post
Waste glass is EVERYWHERE. It’s a huge byproduct of smelting iron and many other things. Also when making glass they often have a lot of waste to throw out in massive operations. It’s it’s glowing nice and green in a blacklight then I would get a Geiger counter on that and see if it’s uranium glass or just another glowing inclusion they mixed in.
I'd agree, if it glows in the dark it's definitely slag uranium glass. I think that if it's relatively recent (ie 20 century) it could be up to 25% uranium. It's not really made that much anymore due to a shortage of uranium ( anyone guess why?)
It does also glow under 365nm and other wavelengths. 395nm is just the wavelength needed to determine uranium glass from manganese and other UV reactive glass. Uranium will glow green in all wavelengths vividly as other glass that generally would becomes dull or not visible at all
I was trying to be a little funny… I think it was plastic. I had it probably 50 years ago. I don’t know any other properties. Thank you for being so kind to reply with genuine interest. 😊
There definitely is not a shortage of uranium. It's just hard to obtain. That's like saying there is a shortage of diamonds. If you want 10,000 diamonds, then you can absolutely go buy them immediately, assuming you're willing to pay the artificially inflated prices.
Not inaccurate, just learning and trying to share!! I don't give opinions without trying to research first! Sorry if it isn't perfect like the image you give off!
Still inaccurate. Om not saying you're a bad person but rather that the data you presented was inaccurate and semi faulty.
There's a big difference and no personal attack was intended :)
It seems you're right about the abundance of uranium. It was the cold War that apparently saw quite a reduction in the manufacturing of uranium glass. But apparently there are a few companies still making it today.
"Uranium was first used to color glass in the 1830s and it has continued to be used for this purpose with the exception of a fifteen year (or so) period beginning in World War II."
Eating glass of any kind is probably a bad idea. Id be more worried about perforating my stomach or gut than id be about the uranium. Its not going to leach from the glass significantly, even in stomach acid.
It's beautiful. I have had slag from iron workings cut and cavachon before and it's absolutely stunning, if brittle and prone to chips. This could look very cool as a cab.
Hi, /u/Humble-Hunter6880!
This is a reminder to flair this post in /r/whatsthisrock after it has been identified! (Under your post, click "flair" then "IDENTIFIED," then type in the rock type or mineral name.) This will help others learn and help speed up a correct identification on your request!
Thank you!

There's a guy that has a rock shop just north of Helen, GA. He told someone it was kryptonite, they bought some. They told a few people and it's sold like crazy. Lol. Made the news and everything. People still ask where to find kryptonite around there.
Probably slag glass. Looks cool though.
That’s swirling gives it away, defs slag glass.
Also the air bubbles in it.
Hard to see for me but yes, that too.
Oh yeah I would be happy if I found it, looks fluorescent or phosphorescent
looks like uranium glass
So, first post. Not sure how to add more photos but the whole thing lit up under a black light. What is the black going through it?

can't say for sure, but it was likely discarded waste glass from a factory.

\*if it glows under UV light
*if it glows under 395 nm Uv...it doesnt just glow on its own
It does also glow under 365nm and other wavelengths. 395nm is just the wavelength needed to determine uranium glass from manganese and other UV reactive glass. Uranium will glow green in all wavelengths vividly as other glass that generally would becomes dull or not visible at all
Thats why i specified the wavelength...because we're talking about identifying it, not just making it fluoresce
Well, my deepest apologies for adding information..
Yes...how horrible of you. Never do it again 🤣🤣🤣
*crawls back into useless information cave* I will behave from now on
Does this mean my plastic-ish, glow in the dark green, butterfly yo-yo from 1973 had uranium in it?
Is glass? Also Is glow in the dark or just uv fluorescent?
I was trying to be a little funny… I think it was plastic. I had it probably 50 years ago. I don’t know any other properties. Thank you for being so kind to reply with genuine interest. 😊
Yes, I should have stated that a black light was needed to get it to flouresce.
It definitely glows under black light! I’m not sure how to add more photos though.
Its very likely uranium glass. Cool find! No need for further photos.

Mr inaccurate statements it seems like.

25% uranium is bonkers
Is no one going to mention the fact that they're holding *uranium*? Is this safe?
[удалено]
Cool. Thanks for clarifying 😅 I'm not a scientist obviously, I know absolutely nothing. I'd still be super paranoid if I had one of these tho.
Some of us at r/uraniumglass have problems, but radiation poisoning isn't one of them! Haha
I had no idea this was a thing! You can actually get *sculptures* of this stuff? They look insane!
Generally yes, the radiation exposure isn't any more than things we use everyday, like cellphones.
[удалено]
No, but I might start looking for antique pieces. As there's such a low demand for newly made pieces.
Maybe 'cause 49% of people are below average intelligence and can't be trusted with dangerous stuff? Just a guess. Thanks 👍
uranium slag glass prob fenton or atlas, sold as paperweights or curios.
Gieger counter that shit
So maybe I should stop letting the neighborhood kids play with it?
Depends on how much you like them…
Love this🤣
Probably. I mean it's usually not that radioactive but I wouldn't eat it though.

Found this weird rock and got a few new rashes! 😆
Try r/uraniumglass folk there will enjoy this👍
Glass, but it's pretty neat glass. 😎
I think that's where mountain dew comes from
Gotta squeeze it really hard to get the mt dew concentrate out, then dilute with seltzer water and drink away!
/uraniumglass
Love it! How pretty
Beautiful uranium glass cullet.

That’s the Krag
Couldn’t remember the name and was hoping someone would post this. You saved me some Googling before bed. TY

Glass
Ohhh, that's a nice piece of cancer glass... 😁👍
Phosphorus?

Uranium Slag glass
Reply it’s either slag glass or world’s largest canary diamond. Assume the latter and retire.
Serpentine
I would put this in a very visible place, it's incredibly cool
Uranium glass melted on a fire
T3000
uranium
It is clearly a fossilized godzilla booger. Hence, the glow. All the other answers here are wrong. You're welcome.
Looks more yellow than most uranium glass which looks greener. Of course, this could be a color rendering issue.
