Original Video @NileRed • Making uranium glass Nuclear Engineer Reacts to NileRed "Making Uranium Glass" Radiation Dosage Chart: informationisbeautiful.net/vi...
Thank you so much for watching! If you are interested in seeing my reaction to another crazy homemade uranium experiment, please check out my reaction to Styropyro's URANIUM CRAYON! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-GuoAQ4SXtv4.htmlsi=4RMyLLdiW38fIEzz
Nigel was on the Trash Taste podcast, and he talked about this project. He asked the Canadian government about the legal implications of amateur/private citizen chemistry using uranium. What he was told was that the laws in Canada around radioactive materials only apply to using them for their radioactive properties. Therefore because the fluorescent property of uranium glass comes from its chemical properties and not from its radioactivity, legally he could just throw all his radioactive waste in the regular trash, but they “strongly prefer [he] didn’t”. 😂
@@tillburr6799 That would be the country we are the hat of. Canada'd be like, "We don't have a reason to send people with horses to trample you, don't give us one and clean up your messes or we'll hit you as hard as the maple syrup thieves."
@@Natso_1 I mean, Canada the only nation where the cops are more corrupt than it's own government, and it's government is the definition of corrupt. Canada: Horse police tramples elderly lady and she ends up in hospital with broken bones... also Canada, no one was hurt today, I don't care if you got video evidence of us harassing the citizens.
i love Nilered, but dont worry about safety! He built his own personal lab for these videos, complete with fumehoods and plenty of storage and PPE. He also has his own glassware (the beakers are all labeled "NileRed")
@@k1zer100 pretty sure he built one into his house or something. He used to do them in his kitchen but that's gets pretty nasty quickly. He should have a video of his lab somewhere. Maybe on Nileblue
@@k1zer100he used to do these out of his parents house but at around 1 million subscribers he had saved up enough to make a lab, he rented a like 4 room places, broke one of the walls to make a room bigger, and bought all he needed to do what he needs (including PPE) he has a couple videos on this process and it's genuinely really cool. Online resellers were his savior apparently lol
@@k1zer100 He is renting a space for a lab, it is not inside of his house it is a separate office space. There are some videos on his second channel Nile Blue of him moving into the lab a few years back iirc!
Yep, Nile Red/Nigel has a degree in chemistry and is a real pro. Some of his experiments have spanned months, and he has a remarkable tenacity to stick with and repeat things until he gets it right.
Always admire Nile's attention to safety. Out of any science youtuber I've seen that does chemistry, they are the safest, despite working with arguably far more dangerous things
Actually, that makes perfect sense. When working with more dangerous things, you should probably be more careful. For example, I don't see why someone like Thought Emporium would need to use safety goggles, when they're working with living cells.
@@cobaltchromee7533 I don't even mean in scale with the type of work done, I just mean in general, I feel a lot of science youtubers don't have proportionally appropriate safety standards
I love NileRed, he'll casually do some uranium chemistry and then turn around and say "I've never made glass before" as if that were the difficult/dangerous part 😂
I'm a fan of @NileRed and I do believe he was working with a lab-grade fume hood at this point in his RU-vid career, and at his own off-site lab no less. Some geniuses have all the luck 🙂Also worth noting that he has a video about the cleanup from this experiment on his NileBlue channel which is also a good watch.
Something worrying that was found out a few years ago was to do with “negative ion bracelets” or something like that, basically similar to healing crystals. What was found was that some of these bracelets and necklaces, mixed in with the silicone were thorium particles and were radioactive enough to cause some damage if you used them as intended. Also since they were just mixed in with the silicone, the thorium could probably come out/break off during everyday use, allowing the thorium to get inside people. There were a few RU-vid videos on it but I can’t remember who by.
not only just thorium being embedded in the silicone, but also thoriated blankets and other items that could potentially contain loose thorium powder which is not only easy to potentialy spill but also inhale. those bracelets are probably the safest form of that garbage ironically.
For your personal enrichment, yellowcake is a bright yellow, and most of the chemical processing of spent fuel is also quite yellow, being oxides, etc. ALSO as a glassblower, you CAN buy uranium glass rods, theyre just very expensive and rare. old stock mostly.
Nigel, or Nile, is my favorite education-based youtuber, and I appreciate this look at his stuff. I'm enjoying you watching and educating along with these kinds of channels.
First time seeing your channel, but I'm a long-term fan of Nile. All his videos are extremely well detailed, and he even has videos about the cleaning process of the different chemicals that he used. He has videos about his entire lab setup, which is honestly impressive for someone doing RU-vid videos. He loves what he's doing, and it shows in the videos. Spending days, or even weeks, on a single video idea for him is nothing. Some of the experiments he did took MONTHS.
Oh yeah, thats 99% why "radioactive = green". Its because from radium painted glow in the dark watches and clock faces, uranium glazed ceramics, uranium glass, uranium in jewelry, etc. It certainly didn't come out of nowhere lol
@@XtreeM_FaiL Sort of / depends. Many lights, and presumably phosphors, put out UV and use a coating. In this case, the uranium can act as that coating.
Uranium salts were also used as a pigment for bricks. Early in my career, I worked at a research facility which was built in the early 20th century. A radon assay was done in one of the buildings and radon was detected in the corner rooms. It turned out that the source of the radon was the yellow brick in the walls.
That is so cool... and horrifying. In my country Radon buildup is a common problem, and your comment has me wondering whether the yellow bricks in some of the older houses may be adding to the natural levels.
The reason the non-florescent uranium compound becomes florescent in the glass is because the uranium gets oxidized when you mix it with the glass. Uranium can have tons of different oxidation states, but only specific ones are florescent. I forget which ones, +12 maybe? Regardless, it's this oxidation state that gives rise to the fluorescence. You could say when the uranium is added to the glass it's not the same uranium compound, but that's kind of a funny way to say that. The uranium is now part of the glass structure, so it's not really it's own compound in the glass.
I love Nile red! I apologize if I haven’t noticed it yet, but have you ever watched Cody , the guy he referenced with the thunder can? He’s awesome and a very worthwhile rabbit hole for reactions
My wife used to be a high school chemistry teacher and we would go to flea markets with a Geiger counter to find household radionuclides, like "vaseline" glass, so called because it's color resembles vasiline. You can actually tell if it was manufactured in the 30's or later by how hot it is. In the 30's, it was made with raw uranium. After the 40's, it was made with depleated uranium. We also looked for "Fiesta ware" plates and bowls. The orange-red ceramic glaze was also made with uranium.
I am delighted to hear an expert opine that NileRed really IS as meticulous as he seems to be in all his videos. I have enjoyed Nile's content for years, and it always seemed to me that he was taking reasonable precautions.
Nigel usually handles most syntheses he does in his fumehood Generally, flat black or white background means its in his fumehood Not always Uranium chemistry from what ive seen in demonstrations tend to be pretty colorful, and often kinda green or yellow or blue. Metal chemistry tends to be colorful Also, uranyl nitrate is extremely soluble, and subsequently toxic, and some sources say it can absorbed through skin. Some say absorption isnt significant, but skin contamination is still significant. The danger is still ingestion, but now its really really solible and will dissolve into the sweat on your hands rather than just sitting there
Bead shops are a great place to look for modern uranium glass ... or at least that was my experience a couple decades ago. A keen eye is almost as good as a geiger counter. I was even able to procure some within the Berkeley (CA) "nuclear-free zone". Alas, the beads were not free. Even so, a lot less trouble than rolling your own.
Depleted uranium actually is used in nuclear weapons just as a tamper instead of core material its density making it well suited to this role coupled with the fact that when bombarded with enough neutrons it too will react
I really enjoyed this reaction; you brought a lot of insight. It's cool when safety-focused people from different disciplines still converge on the same risks and mitigation strategies.
newcomer to your channel here; kudos to you for making this an actual reaction video! Your reactions add a lot to the original video which is what a react video should always strive to be. Too many people just steal other creators content under the name fair use and don't add anything to the video except laughing along and that really annoys me.
This! Actual add of info, Personal comment/stories, warning when he doesn't know much about the subject, ... and so much more. From a little channel i'm amazed. Actual legitimate good stuff.
This type of reaction video may still fall under copyright misuse, unfortunately. When you watch the entire video in full, it's always a little bit sketchy. I, as a general rule, try to avoid reaction videos that watch the entire source video because it really hurts the original creator. Taking little snippets of revelant material is generally a better practice. This guy does it better than most, though the commentary does consume less of the video duration than the original content, which is, again, risky regarding content protections. Legal Eagle has a good video regarding this topic. Worth a watch if you're interested.
@@Malicious2013 There should be, at least in theory, absolutely no problem with copyright infringement, at least according to LegalEagle's late September video addressing the systematic theft of content in the Reaction Streamer community. This reaction is about 40% longer in duration than the original video, and with the additional perspective and information added, it can easily be considered transformative, and it was made more than three and a half years after the date of the original upload, which for this period has realized almost 12 million views.
I work in nuclear reprocessing and waste management. We have a plant that we use for vitrification of radioactive effluent and liquor, it's not too dissimilar to the process that Nile uses here. Obviously it's on a greater scale and the contents are highly radioactive, meaning we have certain safeguards in place. But the end result is still the same, radioactive glass. We use vitrification because it is easier to track and control solid waste than liquid waste. All the liquid that is boiled off as part of the process is filtered of any remaining radioactive particles, then converted to steam which is also used to power some of the other plants on the site. Vitrification is one of the cleanest and safest ways to deal with radioactive effluent.
NileRed is my favorite chemist!! My granddaughter and I watch his videos together. I’m so happy he got his new lab. He has the exuberance and fascination of a young person, with the education and knowledge to make chemistry understandable and fun. He also never quits. He is always trying to make whatever he’s doing better.
I heard once that the reason why depleted uranium shells are so good at penetrating armour is partially because of the density of depleted uranium, but also because of the way it interacts with the armour itself. A typical steel shell (or pretty much any other metal used in ammunition, for that matter), tends to mushroom out at the front as it passes through armour. Apparently, a depleted uranium shell essentially sharpens itself as it passes through armour instead of mushrooming out. This is something I heard about maybe once or twice quite a while ago, and I have not researched the topic, so please take the above paragraph with a grain of salt.
It's oblative so sheds the outside off rather than mushrooming, while kind of self sharpening it doesn't really get sharp, however since DU is pyrophoric the dust/fragments auto ignite when in contact with the air. So it's a super dense armour piercing dart that doesn't mushroom out, sets things on fire inside and outside the tank (such as the big autoloaders in the Russian tanks leading to the turret popping off like a high powered party popper.)
We use boric acid in glassmaking to lower the thermal coefficient of expansion, which reduces strain as the glass cools. That’s how you make old-fashioned pyrex. 1100°C is actually a little cool for borosilicate. The person who taught my wife and I glassblowing used to run the glass furnace up to about 1200°C to "fine" it, and that was a soda lime glass.
5:35 I built my own counter from a cheap solder kit for 20 bucks. I found the asphalt outside my flat is about 4 times more radioactive than the woods around it I was looking into building a gamma ray spectrometer, but the crystal alone would come in at hundreds of money units. Certainly not the price range for me for something just to toy around with. 36:40 most cheap counters that offer measurements in Sv/h or similar are calibrated to specific materials, like uranium. So when it detects some amount of particles, it assumes those particles to be in proportion as per the calibration material.
RU-vid randomly reccomended your channel and I'm glad it did. This was great content especially considering your education, background, and expertise in the matter!
I heard that the association between radiation and glowimg green originally stems from WW1. They used to paint the watch faces and compasses with a radioactive paint that would glow green at night and in the dim trench light (I think radium). I think many just assumed that anything radioactive glows green. Personally i like the blue more.
I've been watching NileRed long enough to know that usually when he's showing chemicals outside of containers like with that uranyl nitrate, it's under his fume hood. So you can rest easy on that one, dude. Also powdered sodium diuranate is the forbidden mac n cheese powder.
If you wanna check more about his safety steps and his setup, he has another channel for that called NileBlue. I think he has a cleanup video for this project specifically on there.
@@AB-80X I mean, whatever is interesting to him? I like all of NileRed stuff; the 'food' related ones are interesting, like Gloves to Grape Soda. But literally anything that strikes his fancy I'd be happy to watch more of. What do you mean 'safety and legal', you mean copyright strikes? If so, its entirely at the discretion of NileRed. Im not under the impression hes anti-reaction videos, so I don't think there is a high likelihood of any real risk of doing a video from him every so often. Otherwise, Im not so sure what you mean.
I pick up and deliver at the Fiestaware plant in Newell, WV on occasion. I took my radiation detector in there once and it spooked me. Even though they stopped making radioactive dishware decades ago, it's still fairly radioactive for a factory. That side of the factory is now a tourist stop and the gift shop area iirc. Definitely worth checking out if you ever end up along the Ohio River in WV.
Also he has a video on the cleanup process behind this experiment, it was interesting to see everything that went into it and that he properly handles all the waste and contaminated equipment
That stereotypical green glow also occurs when you expose quite a few secondary uranium minerals to a blacklight. These tend to form on top of uraninite deposits (which are mostly black) where the uraninite reacts with the elements dissolved in groundwater and oxygen. I've got a piece of autunite that under UV also gives an intense green fluorescence.
Depleted Uranium is used in thermonuclear weapons as a tamper, and the neutrons from the fusion reaction cause it to undergo fission itself, significantly increasing the yield.
This guy does some of the coolest stuff. On NileRed, he has his more serious projects, like making cherry soda out of paint thinner, transparent wood, or bromine (his favorite carcinogen). On NileBlue, he has his more silly projects, like making the world's purest cookie.
I've seen uranium glassware in a glass museum in Passau, Germany. The pieces I saw were all green. I think they were late 19th-early 20th century. I seem to recall a physics textbook that listed the refractive values for several types of glass, and uranium glass was much more refractive than the other types.
I grew up back in the 70's in Crystal River Fl and I remember going through the nuclear plant while under construction on a school feild trip. We also were able to tour the 2 coal fired plants as well. (it was a different time! I can't imagine that being allowed today!!!). A few years later we were given a tour through the operating nuc plants control room (again, can't imagine that today!!!). I lived within the 5 mile "Kill Zone" and I remember the sirens were at the end of our road... Pointed away from us 🙂We used to kid out of towners that we glowed at night ;-) I remember some of the best fishing ever at the warm water outlet of the plant!!! Red fish especially enjoyed the warm water!!! Later on they built 2 more larger coal plants and had cooling towers for them, most people thought they were for the nuc plant, but they weren't... I was able to tour their costruction as well and remember hollaring in the tower and how it echoed ;-) Also got to stand in the smoke stack b4 they put the guts in it and was amazed at how much it swayed in the wind!!!(It was 600' tall and my friend (who eventually wound up running the nuc plant) asked if I wanted to go up in the elevator to the top of the stack... NOOOO was my answer ;+) Great video sir!!!
NileRed has done some impressive organic and inorganic chemical processes. He'll start with something like Nitrile gloves and end up after numerous reactions with 'grape soda'. Love watching him and he does work in a good lab.
Uranium glass can still be found in antique shops. You can find the clear, lime-green glass as well as (usually marbles) a greenish, petroleum jelly looking glass. These, too, are fluorescent under UV.
It always amazes me that everyone has the same examples for the various levels of exposure. Dental scan, airplane trip, banana, etc. I assume it's from everyone having similar charts when they learned it, but the consistency is still impressive.
As I've heard french comercial reactors use uranium nitrate in their fuel pellets, and I've heard it from Rosatoms's representative interview talking about enrichment and production of some quantities of fuel for the french.
For a reference, here are the temps/targets I use when doing fusing and slumping art glass: (I work with System 96 glass, so garget temps will vary.) from Room Temp to about 1,000 Deg F/357.8 Deg C - Fragile zone. Solid glass in this range is subject to thermal shock and can shatter. Not an issue for making powder into glass. 960 Deg F/515.6 Deg C - Soak target temp to allow glass to relax and anneal, so it won't likely shatter on it's own. 1250 Deg F/676.7 Deg C - Soak target Temp when ramping up temperature. Also edge of plastic/fluid state where glass is soft and taffy like. 1350 Deg F/723.3 Deg C - Soak target temp for slumping panes of glass into molds. 1400 Deg F/760.0 Deg C - Soak Target Temp for making smaller bits of glass stick together (Fusing). At this temp, glass retains it's sharp edges and corners. 1450 Deg F/787.8 Deg C - Soak Target Temp for Fusing. Used to soften the edges and corners, but still leave them intact. 1500 Deg F/815.6 Deg C - Soak Target Temp for Fusing. Used to take glass near puddle like. All edges and corners melt off and round out due to surface tension. 1700 Deg F/926.7 Deg C - Soak Target Temp for Casting glass in a mold. Mostly used for solid chunks being melted down inside the mold. 2300 Deg F/1260 Deg C - Target temp for melting glass, especially for "glory hole" kilns. This is the temp for pouring glass into a mold. The kiln I have can only go up to 1700 Deg F, because it's a small kiln used for slumping and fusing glass. I have ramped it that high in an attempt to make glass spacers for a fountain I never finished. I don't know how fluid Glass blowers need their glass to be, but I assume it's somewhere between 1700 Deg F and 2300 Deg F. (I'm being lazy and not looking it up.) For what Nile needs, I think he needed to go hotter. I don't remember what I posted in his video when I watched it a while ago. The nice thing is he doesn't need to slowly ramp up the temperature in the kiln he's using because he's working with powder and not solid glass chunks. HOWEVER, he will have to SLOWLY ramp down the temperature and probably have a few soak holds to anneal the glass so it won't just shatter. Don't remember if he did that. Luckily, they're smallish pieces, so he can be a little aggressive with the cool down. Larger pieces have to go as slow as you can and then even slower to keep the temperature equalized in the piece. EDIT: If you want to see if there is stress in the glass (from how it was created), you need a light table and two pieces of polarized plastic. Place one polarized sheet on the light table. Place the glass piece on top of it. Then place the other polarized piece on top and turn the top piece (90 Degrees) until the area around the glass piece is black. The light will go through the glass and be visible. Any stresses in the glass will show up as lines and the cloudier the piece, the more stress it has and likely to break. However, Tempered Glass uses this stress against itself to make the glass incredibly strong and likely to break into cubes instead of shards when it does break.
I'm hindsight it's ridiculously obvious that a hairline fracture in glass would polarize light, but I would never have thought of it. Physics is so damn cool.
You've probably held a lot of uranium glass and just not known it. Most antique green and yellow glass has some uranium content to it(and some white glass--commercial Fenton flower vases from the 60s and 70s come to mind). It was a fairly common ingredient in glass for a very-very-very long time. I used to work an antiques shop, we'd display it under a backlight, and walk around thrift stores and yard sales with a Geiger counter looking for items.
I lived near a pottery artist as a kid. She had drawers full of various powders for ceramic glaze. One drawer contained about 10lbs of powdered uranium ore. Makes the bright orange glaze once fired on pottery.
Awesome video. I also love NileRed videos and use some of them in my physical science class. I have a uranium glass ice cream dish from the early 1900's and a Fiesta Ware Uranium orange bowl from the 1950's. The Fiesta Ware bowls were manufactured into the 1970's (until around the time of the Three Mile Island incident... go figure). The glass ice cream bowl fluoresces beautifully but does not even tickle my cheap Geiger counter. The Uranium Orange bowl does not fluoresce but measures strongly on the Geiger counter out to a distance of about a foot (20cm). Both are quite safe for everyday use as long as you don't eat the bowls... of course then the immediate problem is not the uranium but the fact that you ate glass and ceramic bowls. :)
I really enjoyed watching your reactions and commentary, after having watched the same video earlier today. I have several mineral specimens containing Uraninite (U oxide) and/or Autunite (a complex Uranyl Phosphate), which I keep in a lead-lined styrofoam box. The oxide doesn't fluoresce but the phosphate does; I suspect it has to do with the oxidation level of the Uranium. BTW, I found that the PRM-9000 retails for $679.
I used to do glasswork for fun. I still have all the stuff. I have one rod of uranium glass somewhere. Someday I'll make something cool out of it. Anealing the glass is 100% required. Glass kilns have timers to control the ramp down. You can also see the internal stress with polarized light. If there's and internal stresses, you don't sell the piece.
I thik the green glow myth also comes from radium and tritium radioluminescense as green is the brightest and most common color used with zinc sulfide being ideal for the purpose. I wonder if if a self illuminating phosphorescent form of uranium glass that illuminates itself with charged particles is possible. Like a self glowing crystal that doesn't need a phospor coating.
I really appreciate seeing two knowledgeable people discuss a topic. Chemistry and Nuclear Physics are topics that probably 99% of the population will never know the details of let alone feel like they have any truck with, so seeing a video narrating the process of making uranium glass and having commentary by an expert--and that BOTH videos are so digestible by the layperson--is a really cool window into an otherwise mystical realm that we could never hope to get to. Thanks for sharing!
You can easily find vintage & antique uranium glass bowls, dishes, cake plates, custard dishes, candle holders, cups, mugs, even glass lamps, etc. etc. at thrift stores.
He has a video on his second channel NileBlue that goes over how he handled the waste he generated, it's only 5 minutes so probably not worth making a video on but might be an interesting watch for anyone curious.
I'm not a chemist, but always wonder where the fumes in a fumehood go - surely it's not just vented outside. How are they treated? It must be more sophisticated than something like a carbon filter?
Organic chemist here. It really depends on what you are working with. I work with Fluorinated Organophosphate compounds which can be extremely toxic and dangerous, as part of alternative pesticide research. We vent everything though chemical scrubbers. Some hoods use "mechanical" filters that are designed to catch small particles, which you would use in such a case as with NileRed. There are also some chemical scrubbers that can be used in this situation. What setup he uses? Who knows. I'm guessing a mix of HEPA and chem filters. And lastly, in work where you have low level toxicity and low pollution, you simply vent it outside of the building without any treatment. Fume hoods and their filter systems come in a wide variety of types. Ours are as simple as a caustic scrubbers that will react with the vapours given off and thus neutralizing them.
I once visited a lack working with highly radioactive materials, and the filtration system for their "fume hoods" took up as much space in the building as the rest of the lab...
I'm guessing you're aware that different isotopes have different colors when added to glass, many are very beautiful even if they can be mildly dangerous. I always thought it was cool that something in a concentrated solid state thats just gray could be a beautiful color when spread out, however knowing the sciences behind color it makes sense. thank you for giving your input on this video, and I look forward to many more videos.
I was born in the late 60s and came of age before the end of the Cold War. The ever present threat of USSR nuclear bombs falling out of the sky was a low level but constant fear during my childhood. Once the internet was born I found tons of information online about all things nuclear that wasn't easily accessible pre-internet. Because of this easy access, over the past couple of decades I've sucked up every bit of information I can find about nuclear energy and radioactivity: from radium dials on watches to the nuclear fusion explosions kept in check by gravity that we call stars. Discovering your channel makes me super happy. Seeing another content creator "playing" with uranium blows my Cold War influenced mind. I'm really excited to have found your channel and now Nile's. Science was not cool for girls when I grew up and I crave fact based information sources that are easy to understand. So thanks! I think a day of binge watching your content is in my immediate future.
There was a huge industry involving a bunch of quack health things prior to WW2. Things like tanks that made water radioactive, to make it as a "health drink", etc. Radium dials were huge deals back then too. People were using radioactive materials in all kinds of unsafe ways. What you use is highly refined nuclear materials. What most people have access to is more common ingredients.
Uranyl-salts were used in chemistry for qualtiy ananlysis in the lab - I dont remember for what exactly Btw: Some sort of glass is used in analytical chem, called boron pearl, which is used to identify small amounts of metal by the color of boron-pearls Is Cadmium used in stopping the fission in any kind?
Radioactive Thorium in optical lenses was pretty common until the 1970s, particularly for military and industriall use. The majority were recalled, but there were consumer models which can still be found.
Eating out of it isn't too bad, microscopic glass particles will just pass on through. It's when you breathe the particles in that you start having real problems, because they get stuck in your lungs. This is the same problem that occurs with cigarettes, as the mineral fertilizer used in fields is contaminated by lead-210 and polonium-210. The same fertilizer is used to grow food in the USA, by the way, but food doesn't normally get trapped in your lungs like tobacco tar.
I am a collector of uranium (and other types) glass and seeing your video was very helpful in answering questions about the radiation side of it. From what I have been able to find in research uranium being added to glass goes back to about the 1830s. Although some glass dated back to the time of the Romans has been found with uranium in it. A side note, uranium glass will floress in different shades of green under differing wavelengths of light. Playing with 395 nM and 365 nM black lights will give differing results. Also, different types of glass will glow different colors under a 365 nM light, cadmium glass is very cool as is lead glass.
Reminds me about the light switches my Grandparents had in their house. They glowed greenish white in the dark even in the middle of the night. I later found out they had radium in them to make it glow. The plastic got really brittle after 40 or so years and we replaced all of them. I have most of the stuff in a metal can in the basement. :-/
It is also called Vaseline Glass. Vaseline Glass has a low uranium content. It is somewhat translucent, looks kind of like Vaseline. But under a UV light it flows bright green. My wife has a bottle that she found in the mud on the banks of the Mississippi when she was a kid.
I have several pieces of Venetian uranium glass. It got really popular in the 60s, space race, moonshot, Cold War themes. I have mine on a glass shelf with black light illumination
