Uranium Glass
- Ameo 7y agoA really neat video by a Youtuber I follow - NileRed, who creates a lot of interesting chemistry content - was released a few days ago where he produces Uranium glass from scratch: https://www.youtube.com/watch?v=RGw6fXprV9U https://www.youtube.com/watch?v=RGw6fXprV9U If you're interested in the process and chemistry behind it, it's a very informative and entertaining watch.
- xenocratus 7y agoSaw that a few days ago, it's amazing how much it glows from such a small concentration of uranium.
- kjs3 7y agoFortunate, since you wouldn't want a really large concentration laying about.
- madaxe_again 7y agoSeriously. I was surprised at how much the glass was emitting. I should perhaps have a word with my mother, who not only uses uranium glass pitchers, drinking glasses and serving bowls day to day, but also eats off vintage fiestaware. https://en.wikipedia.org/wiki/Fiesta_(dinnerware)#Radioactive_glazes https://en.wikipedia.org/wiki/Fiesta_(dinnerware)#Radioactiv...
- zenexer 7y agoIt’s not emitting the light on its own, and the fluorescence is unrelated to its radioactive nature. Uranium glass is generally considered harmless to keep around on display as long as you’re not keeping it close to your body for long durations. That being said, you shouldn’t be eating or drinking from it. If pieces chip off and get inside your body, that can be bad.
- wcoenen 7y ago> it's amazing how much it glows It doesn't glow by itself, and it is unrelated to radioactivity. It's just fluorescence under a blacklight.
- mkaic 7y agoCame here to say this. Nile’s videos are pure gold, figuratively speaking.
- oehtXRwMkIs 7y agoFor anyone wondering, it seems like it's (usually?) safe to eat/drink from uranium glassware. http://www.hps.org/documents/consumerproducts.pdf http://www.hps.org/documents/consumerproducts.pdf
- saagarjha 7y agoI have heard that acidic foods and drinks can leak the uranium from the glass like any heavy metal.
- rdlw 7y agoTangentially, the tomato was thought to be poisonous by Europeans because the acid would leech lead from pewter plates. Here's an article, though I heard about this from the Hawaiian Pizza episode of The Anthropocene Reviewed. https://www.smithsonianmag.com/arts-culture/why-the-tomato-was-feared-in-europe-for-more-than-200-years-863735/ https://www.smithsonianmag.com/arts-culture/why-the-tomato-w... Edit: Acid leaches lead, not acid. Misuse of 'leech' preserved for posterity.
- samatman 7y agoSplit the difference and you get leach, the actual word y'all are looking for. English is such a trip!
- kjs3 7y agoI had always heard the tomato was thought to be poisonous because it's part of the Nightshade family (Solanaceae), many of which are poisonous. https://www.sciencedaily.com/terms/solanaceae.htm https://www.sciencedaily.com/terms/solanaceae.htm
- PeCaN 7y agoThis seems unlikely since many are edible and some (e.g. potato, eggplant, tobacco) were eaten concurrently with the tomato confusion in Europe.
- bduerst 7y agoMy chem lab in college had some Fiestaware, which was similar in that it had uranium glazed ceramic. They stopped making it in the 1970s but you can still find it floating around somewhere online. https://en.wikipedia.org/wiki/Fiesta_(dinnerware) https://en.wikipedia.org/wiki/Fiesta_(dinnerware)
- Bootwizard 7y agoOh god I used to have some of these!! I inherited them from my grandmother. Should I be worried about having used them for years?
- Gibbon1 7y agoI think Uranium has low bio-availability a high clearance rate and not particularly toxic. So likely not. Uranium is also everywhere in ppm quantities.
- jcranmer 7y agoIf you used that dinnerware every day, you've received about as much radiation from the dinnerware as you have from the potassium in your body (about 400µSv/year). You'd need about 100,000 µSv/year to get heightened cancer risks.
- Tyr42 7y agoUpthread people are saying is not recommended. Not because of the radiation when eating off it, but if there's any chips or anything you should end up with uranium inside of you, which is significantly worse. But as long as it's intact, no big deal. (I guess, I'm not an expert, why are you listening to me?)
- cknight 7y agoThe colour under UV immediately brought to mind the space LEGO sets I enjoyed as a kid in the early 90s: https://lego.fandom.com/wiki/6923_Particle_Ionizer https://lego.fandom.com/wiki/6923_Particle_Ionizer I wonder if uranium glass was actually the inspiration for the neon green elements in these pieces?
- p1mrx 7y agoThanks for resurfacing my childhood disappointment; I had one of those sets, but no black light.
- aikinai 7y agoYes! I thought the exact same thing. I used to love that color.
- hermitdev 7y ago> space LEGO sets I enjoyed as a kid As a kid? Now as an adult with disposable income, I can get really awesome LEGO sets, sets I really enjoy building. I prefer Technics, but also have several star wars sets, including the model death star (not the one with the minifigs) and the original 32" star deatroyer. Post Christmas this year was spent building a lot of LEGO City sets. I also have the Saturn V and ISS sets, both of which are awesome.

- Fnoord 7y agoSharp catch! I also played with "space" Lego from around that time (including with that colour). I always found it more greenish yellow rather than yellowish green. I guess because I liked to combine it with yellow, rather than green. YMMV, obviously, but I do find the colour rather different than the one in this article.
- anonsivalley652 7y agoMy mom and aunt have both collected vintage uranium glass for years and years. (I wish they didn't have so many tchotchkes though.) Honestly, two bananas a day would give you more radiation... it's not something to worry about.
- MengerSponge 7y agoFun fact that isn't on its Wikipedia page: Uranium glass is particularly impermeable to helium, making it less depolarizing to helium-3 than borosilicate or even pure silica glass.
- trm42 7y agoOther interesting radioactive glass variant: thoriated glass, which has been used in photography lenses: https://en.wikipedia.org/wiki/Thoriated_glass https://en.wikipedia.org/wiki/Thoriated_glass https://camerapedia.fandom.com/wiki/Radioactive_lenses https://camerapedia.fandom.com/wiki/Radioactive_lenses Those lenses have good metal encasing and the radiation is so small that there’s no real problem except the lenses start to turn to yellow with age.
- penagwin 7y agoMy understanding is that exposing yellowed lenses to UV light will return help it un-yellow. That type of glass was mostly only used in older lenses - which with the right adapter they still work great on modern cameras!
- Shivetya 7y agoI collect a lot of vintage glass, Vaseline/Uranium glass is still for the most part in a less desirable category namely many who collect look for pieces that look good in natural light. For the most part its comes down to, it is neat to show to friends once. There were so many glass companies from Virginia to Ohio and most dabbled in this for a run or two so good examples are easy to find on ebay cheaply. I found the more solid pieces to be best for the light effect.
- friendlybus 7y agoWhats the coolest vintage glass?

- nabla9 7y agoUsing uranium class or ceramics for eating is not recommended. Not because the radiation it emits while intact. Alpha radiation is the primary form of U238 and it does not penetrate skin. But the chip and wear in everyday use means that you get particles inside your body. Alpha radiation inside body is bigger risk and uranium is also toxic and reproductive toxicant. The largest radiation hazard in home is radon gas in indoor air. If you live in an area with lots of radon emissions it's good idea to have ventilated crawl space under the house. https://www.epa.gov/radtown/radioactivity-antiques https://www.epa.gov/radtown/radioactivity-antiques > Do not use ceramics like antique orange-red Fiestaware or Vaseline glass to hold food or drink. They can chip, and you can ingest particles of uranium with your food or drink. >Dispose of any broken radioactive antiques. For instructions on proper disposal, contact your state or local radiation control program.
