Nice uranium jelly !

Isn't uranium glass yellow? I thought this glow was due to the manganese. Thanks for the compliment.

It is manganese that will turn purple.

I thought he shape of that jar looked familiar. I dug two of these in a light SCA last year. I will check when I’m home from our shore house. I think it’s the same design. Some versions were sold as resealable jars and small bowls. I’ll send a couple more pix from home. Let me know if you think it’s a good lead.

Not yellow that I have ever seen. I found some in a dig of like 300 bottles from a WW2 era dump, but unfortunately it was all shards. It had a purplish tint like you described, but under a black light it glowed just like yours did, with a beautiful light green tint.

That's the clarifier manganese that is reacting with the uv light. It oxidizes purple.

Uranium glass is more of a yellowish green. Purple glass is pretty weird to find in a WWII era dump though, since manganese which turns the glass purple had been phased out thirty years before that. Real uranium glass would be expected in a dump of that era. This is what uranium glass looks like:

It was pretty much exclusively used for housewares rather than bottles which would have contained products. The only exception I know of is its occasional use for seltzer syphon bottles, but that was not common and I've never seen one in person before.
