LOL you sound like T

I just got uranium glass saucers from my grandma's estate. Super excited. I meant to bring my uv light with me to look through everything.....but I forgot and when I saw some pale green I had my suspicions and took them home and WOW do they glow bright.........now I feel like I have to go back cause I had no idea so many different colors color be uranium glass but...... don't want my mom to throttle me.....(My grandma mostly collected pink depression glass) Been looking into if there is any reason other why they would glow so bright and it looks legitimate so cool!

3:16 you have supercharged it with the UV light, since purple light is the strongest colour, oppositely, red is the weakest.

Well hello there SPEGTACULAR!!! Fancy finding you in the wild.

Have you ever happen to come across blue uranium glass? I came across some light blue plates that glow green under 395 nm and also a deep blue glass basket that glows intense green

Is it toxic to use every day or what?

Are you saying size don't matter?

Sadly I left an open sugar bowl that was Uranium glass and someone else got it !!! 😢

I bought a pair of Amberina vases and an Amberina Basket and a Vaseline glass white opalescent vase !!!

Physicist here, photons bounce around, not "ions"

It is ratio active

Uranium glass spot price is going up!!!!

One way I tell for sure is I use a Geiger counter.

Cheers mate

Spectacular video. 😉

So 395 is better because you can see the manganese glass blue istead green that look like green of uranium glass

I’d get two or three for that price, crazy good deal.

Great information! Thanks

Love that train!

now why tf are my blue light glasses growing like this

Wonder if my eyes going bad. The round covered sugar bowl in the center never appears to glow with either light from my viewpoint.

The lamp is so beautiful OMG😍😍😍

You are comparing a 395 without a visible light filter to a 365 with a filter. I think this is the main reason you are seeing such a drastic difference in fluorescent response with your old clear glass. You are getting some visible blue light wash from the 395 due to the lack of visible light filter. You don't see the green fluorescence because it is washed out by visible unfiltered light. With the higher concentration of uranium the glass is so bright it outshines the blue wash. 365 is a higher energy, shorter wavelength light than 395 so for minerals or glass that are more responsive to that wavelength they will appear brighter under 365. Where did you learn manganese causes a weak green fluorescence? Interesting. I hadn't heard this before. I think old glass was not very pure and when they intended to have clear glass it may have some trace uranium in it. No one back then had a black light to know the difference. Thanks for the interesting video!! Liked.

I just use my Radiacode Dosimeter.

This was an excellent video thank you for explaining it!!

Awesome collection spegtacular!

So many errors... Where to begin? First of all, it's not, "spectrum", it's "wavelength". And its not, "black light", it's "ultraviolet". "Black light" specifically denotes a 365nm, tube-based, UV lamp. And leaving out, "nanometers", is not helpful. At least once you should be saying, "365 nanometers" so viewers have some idea of what the delineation indicates. Next, put your 395nm flashlight into a drawer as a spare (though 395nm is useful for making selenium and cadmium glass glow but they are less common. Save it for them). "Ultraviolet"means just that, that humans cannot see the emission. "But", you complain, "I can see plenty of light from the 395nm!" Yes you can, and that's the problem. You noted that some, "black light" was reflecting off of the white bowl you lamped. You can't see UV light. What you're seeing is the tons of visible, violet light emitted by 395nm LED's that you're seeing and that's why, even if an item has some glow to it, that glow is washed out by the visible light. Vaseline and U-glass glow nicely under 395nm, but the entire point is to see the glow from the UV, not from visible light. I have a couple of early, unfiltered Cree 365nm flashlights that actually emit a lot of BROWN light along with whatever UV they emit. Talk about useless! What Vaseline and U-glass collectors care about is the glow. Once you dump the 395nm light, using a properly filtered 365nm obviates all of the bizarre discussions of manganese or uranium. Who really cares what the doping agent is if it glows nicely? A properly filtered light is just that. The best UV LED's, such as Nichias, have a very narrow emission spectrum with the desired wavelength centered as a peak with a little bleed on both sides. But even with such a narrow output, the best results are still obtained by using a UV bandpass filter on the flashlight to remove as much of the visible light as possible. If you're using an unfiltered light, you're still not there. Now, you were stuck on 395nm and 365nm. But flashlights are now available in mid wave, (MW, 310nm) an short wave (SW 254nm). The white bowl that did nothing under 395nm (it actually did but you couldn't see it due to the visible light) and looked pale green under 365nm will be bright, powder blue under SW (MW, depending on the mix), glows a weak, dark purple. This is how my Westmoreland Hen-on-Nest milk glass reacts. Another option is to use a 405nm UV laser, cheap things easily found. Makes Vaseline and U-glass glows like a beacon and requires no filter because there is no emission spectrum: it's pretty much only at 405nm. The downside is that it lights up just a small spot, useless for enjoying items but not awful for determining what glows in shops and flea markets from 50' away.

I bought a 395 Black Light at the HmDpt big box store for $14.95 in 2022. They are available more often in the Spring. Why Spring? Here in the desert...they are used to locate scorpions.and other yuckies. A great tool to have for Vaseline/Uraniam glass verification. Plus, if you are a pet owner, it locates urine accidents and spit-up/vomit areas. (You'll be unpleasantly surprisef.)

Thank you for this I ordered a 395 black light to be correct when determining, I was going to my glass I like to collect and found one was glowing pink under the 365 so now I'm on a discovery lol I get mixed Info on the pink glow so if you happen to know why something Crystal would glow pink or I'm just assuming it's Crystal lol thank you again

365 nanometer, nm, black light can be dangerous to your eyes or anyone else standing close by. The 395 or 400 nm wavelengths are not. It is safer to just use the 395 or 400 nm wavelengths to avoid any problems. If you have a public display, stay with the safer 395 or 400 nm wavelengths lights. The 395 or 400 nm wavelengths are super cheap, and you can see glass fluorescing easily. Also, if you price strip lighting in the 365 nm wavelength, they are very expensive, hundreds of dollars, and they are dangerous to the public should you have a public display. The 395 or 400 nm wavelengths blacklight strips are super cheap and safe. That is my understanding.

Are spirit Halloween uv bulbs 365 or 395?

You should finish the test with a dosimeter

I’ve got a few Kanawha amberina water bottles that have manganese in them and it really brings the piece to life. Which I say is a desirable trait. The subtle orangish yellow areas pop out.

Very nice video. Thank you.

I love the content! Keep up the good work!

If a piece of glass has enough manganese in it it will glow under 395, but as you have shown it’s a more mucky sludgy green glow. One of the best glows is from good old Vaseline glass from around the late 1800 early 1900, a pease of Davidson Pearline is a good example.

9:24 am I mistaken or are those 2 World Fair vinegar bottles? The white one?

Also the one handle / 2 handle matching set are a sugar and creamer set

I prefer using a 365nm light over the 395 because it can pick up UG along with cadmium and lead

Where did you buy your glass? It’s super nice it was wrapped so well! So many pieces are broken at arrival 😢

Does yellow canary glass (vaseline) glow brighter than green uranium glass?

Hey Speg I posted a few shorts lately. Had some nice finds. Had a brain fart and called 365.. 350 and 395... 375. Probably shouldn't make shorts after paying taxes. 😂 Anyway put a couple on my community page as well. Finding more than I expected. Cutting in on my silver stack. 😮😊

That milk glass with manganese boat is a Remember The Maine a commemorative for the Spanish American War.

Great videos! Very educational. In your video titled ; (THIS matters when searching for Uranium glass! Buyer Beware!), you shine the 395 on what looks like a creamer bowl with a flaired top at the 22 second to 30 second mark. Do you have any information on that bowl and the design on it? My mother has a large uranium planter bowl/vase with that design and I have been trying to identify it with no success. When I saw that on your video I almost crapped myself! Any information would be Greatly appreciated. I could send pictures of it if there is a way to contact you safely.

Thanks for this video, that was my classic rookie mistake..l I lost my mind and bought ten pieces of manganese glass at the thrift store with my 356 in hand. It was a learning experience, I have yet to actually find a single piece of uranium, but I continue to hunt.

What antique mall is this?❤

I found a vase at Goodwill

Is there a good online store to buy Uranium Glassware? My stepson is collecting it now and I would like to get him some. Thank you for the advice and sharing good video. Have a great day.
