Black light fluorescent glass

Many years ago I bought some UV glass from SP that I think Dave Wilson made. I stashed it in a drawer until i thought of a good use for it. I finally used it this spring making hollow murrini, but I really want to know what is the fluorescing element. The glass is clear until it goes under a black light then shines either green (uranium?) pink and orange, I had some that would glow blue but it does not glow anymore. Why is that?
I searched the archives but could not find this information. I am putting something I made with this in a gallery and I need the information for the installation. I figure one of you must know!
I tried to message Dave but did not get a response. Also wondering if any of the pieces are save for using in jewelry as well.

Thanks

Manganese is probably what's giving the pink/orange glow. No idea what causes the blue.

Uranium glow in the dark...

I had a bit of rod, maybe still do, which was light yellow in sun light, but blue or green (??) in black light. I was told it was non-radioactive uranium that was the active ingredient.

It may be Gaffer G-038 (Uranium Green).

It's a thing. Here's the Wiki page for it:

https://en.wikipedia.org/wiki/Uranium_glass

Some that makes a living selling it:

In fact, a whole non profit about it:

Generically for our world the mainstay UV base is going to be uranium green, but some of the other colors might be a phosphor base. You can find "glow glass" out there in a variety of colors, but they have questionable compatibility.

The boro world has a bunch of color shifting colors out there, several that say they have no uranium.

You could email him dave.atomicsolar@gmail.com there's no reason it shouldn't glow anymore, is it still in rod form or blown out? The blue is a lot lighter than the Uranium green or Samarium Orange but the rare earth elements don't dissipate with time so thats a quandary.

This might be of interest for some: https://www.researchgate.net/publica...escent_Ability

CBS now sells a powder that's claims all coe compatibility. There was a supplier a while back that made some stuff that gave the ashes look when coated, real hit or miss if your stuff cracked.

"All C.O.E (grrr...) Compatibility? " One size fits all? Snake oil.

Their words not mine. Secret alien tech?

There was a different company that sold something similar, green was fine with 2.0, but yellow had a 50% loss, blue 100%. They were specifically a blowing additive, but can't seem to find the company again.

Thanks so much for his email. I will contact him. This is not the phosphorus glass with strontium. Iíve been making my own glow in the dark murrini since 2009 after David showed a few of us how at GAS that year. I am talking about the rods that glow only under a black light. One year at Corning they had a number of pieces on display made from the UV glass David sold through (?) Spruce Pine. This is what I am making with it.

I think that was GAS 2001 and the rods were in SP's booth.

well, I was on the board ( about to quit) at NO. I do remember Dave having it at 2001 in Tom's spot. I haven't done a GAS since with the exception of the very last Corning which was I thinkl about four years back.

Corning, I'll go to.

So I got an answer from David. Iím not scientific enough to understand it. He didnít want to give away trade secrets so I got:
Lanthanides
So I have enough from that to write up the info I need for the piece I made.

He didnít know why the blue doesnít glow anymore.

I love CraftWEB!

Such deep trade secrets.

The Lanthanide group is a section of the atomic table which describes a body of elements which have the curiosity of having an inner electron ring capable of giving up, or taking on electrons. Commonly , they're known as the "rare earths". They aren't really all that rare although some were difficult to isolate and purify in the past making them pricey. Many, not all yield up different colors in different wavelengths of light. Neodymium is the one you would see most commonly. Purple in UV Light, Ice Blue in fluorescent.

On a side note, I like what I'm seeing. Love the individual pieces. Not sure what your end set up is, but I've always been fond of edge lighting. That would allow you to bury the source so you're not blasting people in the eye with UV.

Look up Charles Bellows. Heís currently a graduate student at the Inamori School of Engineering at Alfred University. He wrote his undergrad thesis on the effects of rare earths and color. He tested his samples under many types of natural and artificial light, including uv radiation.

Thanks Shawn. Lighting this for an upcoming show has been an issue. I tried UV light LEDS with plans on making a type of shadow box but they were not near bright enough. Same with black light bulbs for spots. So I have settled for it to be ďinteractiveĒ using the brightest UV flashlights i could find on Amazon (UVBeast) and it will be draped over a piece of Ironwood on a flat black board with an explanation of the glass and the flashlights next to it. Since I have been making glow in the dark glass since that same Corning GAS meeting, Iíve spent a lot of time playing with black light. This flashlight is so bright that it shows where my dogs peed in my upstairs carpeted work room when they were little 17 years ago even though I cleaned the pee with all of the recommended cleaning products! It never showed up under those UV light that are sold in the pet industry. Iíll check out Bellows. Thanks!

This is great information! In case you don't have it, here is a link to the full document:

Be careful with eye exposure to UV. Its on the high-energy end of the spectrum.
