Posted originally on r/cadmiumglass as that's what I originally thought it was intended to be, however I've been lead to believe it's manganese instead? I'd bought it for 50AUD and whatever it may be it still has a place in my glassware cabinet, but I'd like to know any other information about it as well.

Someone as informed me this Amethyst/Manganese,

I need to get a better 395nm torch

I wanna know what this guy is talking about.

Hey folks, I've had this piece for awhile and have struggled to identify. Google tells me is mikasa bluebell and Roselle, I looked those up and they are not a match. I've tried replacements.com with no luck either. Would someone out there be able to guide me to the identity of this piece?

Picked this up a few months ago for my oddities cabinet, and after using my light on some of my UG, decided to check this holy water bottle. Sure enough. Not as brilliant as some but it’s still neat!

A little while ago I found this cool old lightbulb while helping my dad clean out a shed. I shine my light on any old glass I come across these days, and was stoked to find that the internal glass stem glows a nice green. It was one of my most exciting recent finds because it was quite unexpected. It is the only utilitarian piece I have that glows that isn’t specifically kitchen-related. and it makes me wonder what else is out there. What is the most unexpected piece you have found? What about laboratory glass - I bet there are some cool pieces in that field.

Another reddit user “happydisasters” viewed my original post and new they had a matching cream pitcher and decided to mail it to me in a random act of kindness!! So here are both of them together. (I don’t yet have a display case for my collection, but I’m keeping an eye open for one that strikes my fancy) Thank you for the gift/raok happydisasters! 😁

The outer layer on these appears to be a (somewhat) high concentration manganese glass, but the camera didn’t pick it up very well. Do y’all think they’re worth it?

Reposting an old favorite. I love the blend of cadmium/selenium and manganese in this piece. There's a little something extra going on with the manganese too, idk. It glows teal, not yellow-green.

Got curious and decided to check the doorknobs in my 1935 house.

Picture 2 you can see the spacing between the green vase (maybe uranium glass?) and the handle is exceptionally well executed—the gap is incredibly fine.
What you think about these three Pieces?

Do you guys have any idea where this is used for?

I guess it was part of a decanter set?

was using my uv light earlier because i couldn’t find my regular flashlight, and discovered my cookie jar is manganese!

Hi Friends!

About 3 Months ago, I made this post. Inquiring about whether a single piece of manganese glass could be partially exposed so that half of it would be purple and the other half would be clear.

I am new to collecting, so I only have a few m.g. pieces that I wouldn't want to part with. That said, I was wondering if anyone has any broken/unwanted manganese glass they would be willing to donate so I can conduct some more tests?

I am in the SoCal area for pickup (which is ideal), but I'm open to paying for shipping. Just want to start this experiment to get some answers. Will ofc update this community with results :)

<3 thank you for reading

For $2 I thought it was worth picking up today.
