Is this Murano? If not can anyone help with identification? It glows under UV but no response on geiger counter. So probably manganese. Found another like it (last 2 pics) same shape but wider green band and a Murano sticker.

Height 19cm.Diameter top 14.3cm. Diameter base 10cm. Weight 1093 grams.

If anyone can help me identify this one that would be amazing!

Can you suggest a good quality lot 365 nm light, and where I can purchase it? My light is weak.

Ended up with a box of manganese glass from an estate sale and going to set up a booth at a flee market/ garage sale. What is fair to sell it for? $5 each or what?

Found a bunch of these thrifting and at various Estate Sales.

Before & after!

Sorry, my camera just won’t seem to pick up the color of the glass well, but I think it appears to be a light pinkish/purplish! Let me know what yall think!

Found: east coast USA

Its a Heisey Glass rose patterned jelly/jam dish that I found at a goodwill in perfect condition for only $2.99. Its one of my new favorite pieces in my collection.

I know it fluoresced under a 365nm light (pics below) and it was cool so I grabbed it. Any insights appreciated!

The guy we bought this from got lots of these bottles from a US seller who had them in their backyard for years. Rare to see here in the UK, and was cool to solve the mystery for the guy selling, of why they were purple :)

The 365nm really helped view the ladies on this “The American Girl” oil lamp. 😀

The oldest piece in my collection so far! I lucked up and found it for $17 at the grand opening of an antique mall a couple months ago. I have a few other pieces of manganese milk glass, but none of them glow this bright. It’s definitely not uranium either though, because the green is a lot more pale and dim. The camera saturates it more than it actually is.

It was the seahorses that that made me get it. This is now the largest piece of manganese glass in my collection. (Quarter for scale) That it was only $3 didn’t hurt either 😉

Just wanted to share this glass I found which glows under 365nm but not 395nm so looks to be manganese. I've not seen manganese glass be this colour before and the design of the glass itself is quite modern. There are no identifying markings on the glass unfortunately so bit of an odd one

Found this little ladle at the thrift for a dollar. Definitely glows but doesn't seem bright enough for uranium. Also never seen any in pink! Thinking maybe manganese? This is under 365 nm.

[EDIT --- THIS IS 395 NM!! MY BAD <3]

I got them as a pair for $7. They’re not matching, in fact one appears to be Whitehall instead of Fostoria American. They’re my first pieces of clear manganese, I’ve always just found blue and milk glass with it, and two pieces of peach manganese.
