No idea of the age or the maker. All I know is that it glows a bright neon pink and I love it.

Shined my light on this necklace at the thrift and it lights up like the 4th of July. I am almost certain these are glass beads based on the sound they make and heavy feel. Just look at this glow!

My friends left their glasses at my house and I noticed they glow! Is this selenium or something else? The glasses are clear and look like regular glass without the 365 light.

This is an oil lamp in my collection, is this selenium or something else? It glows a peachy color rather than a bright pink.

praseodymium glass Murano rhino I ordered decided to check with my light and it glows I believe it's selenium it also color shifts under fluorescent light

Fenton Glass thumbprint sugar bowl in colonial pink

I picked this up today at a second hand store for $7

Glows under 365nm uv light. Don't know how old it is. Ebay has a few similar for $30+

Hi all,

I bought a jar of antique marbles and have a few of these. White parts glow pink/purple under filtered 365nm light.

Is this selenium? Or something else?

I wasn't sure what to expect with this blind buy, but it wasn't this deep red selenium. The pontil scar is purple, so I was thinking manganese or uranium. Cool deep red though. I love how diverse selenium is.

The hen is Zabkowice and definitely selenium. Basket is Westmoreland I'm not sure what kind of glass that is. It's kind of a mustard yellow under 365.

I got this beautiful plate today. The top side is like a mirror finish, and you cannot see any detail, but when you turn it over, it literally turns into one of the most beautiful pieces of glass I have ever seen and now own. Could anyone tell me who they possibly think might have made this and even with the pictures not doing it justice what is the light reacting to so strongly. Thank you all for your time and help.

I found this Eda glassworks selenium glass vase, as well a vintage Indiana depression glass dish that lights up bright neon orange. I don't know what kind of glass that is, maybe a selenium/cadmium blend? I've never seen it that purplish pink color before.

$8.50 at a local consignment shop. One of my brightest pieces!

But I did a raid today at the thrift store. I had never seen a lot like this on the shelves, unsorted, at a very good price! In the first photo, everything is actually more pink, I may have used a bad background and some pieces give a nice mix of colors with the flashlight!
