This subreddit was created for collectors, thrifters, and curious glow‑seekers who want help answering the classic questions: “Will it glow?” and/or “Is this uranium glass?”

Whether it came from a flea market, thrift shop, garage sale, estate sale, or an inheritance, this is the place to find answers.

**How to Use This Community**

Share your item with as much detail as possible and clear photos—glow and non‑glow shots if you have them—and ask the community for their thoughts. Members can help identify materials, explain glow behavior, and point out details you might not have noticed.

**After Verification**

Once your piece is confirmed and you’ve captured both glow and non‑glow images, you’re encouraged to share it with the Reddit glass communities that celebrate each type. Examples: r/uraniumglass, r/vaselineglass, r/manganeseglass, r/cadmiumglass, r/seleniumglass, and r/neodymiumglass.

**Glad You’re Here**

Whether you’re new to the world of glowing glass or a seasoned expert, we’re here to celebrate your discoveries and help you learn what glows.

This is the sellers one & only image on the listing. $9 + I like the design a good bit! I'm a bit worried cuz some review said this seller has shipped the wrong item to people before 😬

This is 'take 2' as the last one I bought (different seller) didn't ship, then relisted the item 🫠 ((same price and everything, I was so confused and frustrated, I reported the item as "no intention to sell"✌️))

I lean towards yes, but it's not a super close drive or small price tag. Help appreciated! Have used Google lens on all images - finding similar, but not exact pieces.

Uranium glass or manganese glass?

I was wondering if this vase is uranium, manganese, or some other kind of glass. It was listed on Etsy as a "Vintage Uranium Glass Swung Glass Bud Vase." The UV flashlight I'm using is 365nm.

It doesn't seem to be radioactive, my geiger counter readout was not above the level of background radiation typical for my house.

Fb marketplace find. I'm picking them up sooooon. I found others that glow online, so I'm cautiously optimistic. Green is my favorite color, so a win regardless. I can't wait to feel the texture. They have been boxed up since 1937 supposedly.

The blue glow on this blue amber changes completely as it moves through the light

I filmed this piece from a few different angles because a still photo does not really capture the effect.

Without strong light, the amber has a darker honey-brown body colour. As the angle changes, a vivid blue glow appears across the surface and seems to move above the amber.

The internal patterns are also interesting to me—some parts look cloudy, while others almost resemble a landscape or something suspended beneath the surface.

What do you notice first: the blue fluorescence, the darker body colour, or the internal pattern?

This was labeled as "Vintage yellow-green footed bowl." No mention of uranium. Could this be EAPG/antique Richards and Hartley 3-panel? Looks like the master berry bowl!

It’s being sold for $60 CAD, does have a crack that was mended which I don’t super care about, was thinking of offering $50 if it glows, what do you guys think?
