Title: Help ID Uranium frit glass
Post by: Sendhandfran on November 16, 2019, 02:10:17 PM
Hi everyone.
I wonder if anyone can help ID this little dish.
Made from uranium green glass with, what looks like bits of clear or grey frit and maybe some trapped air bubbles as well.
The bits are mixed in throughout the glass giving it a rough feel both outside and, to a lesser extent, inside as well.
I've not found one like it and would love to know more.

 :) How unusual. In some pics it looks as if it could be pulegoso glass - which would be full of tiny bubbles, but I can't quite make out the texture in others.
Looking at the outside, I think i can see some straight longish lines - which make me wonder if it could be very old and the surface has crizzled itself, but I am wondering too, it it is just a deliberate rough texture, or if it comes from the presence of the bubbles.
Their remnants are in the shiney internal surface.
It's very frustrating not to be able to feel it.  ;D

I've known these type of pieces as "sweetmeats".  Any markings on the metalwork?  Is it brass?

Thank you Chopin-Liszt &  catshome. It's difficult to describe (it would be so much easier if you could hold it:) the outside is odd. I can't tell what's air or frit. It has a look like it's been treated with acid! I don't know if that's ever done to glass? Can glass crizzle with age? I've never heard of that,lol. I can't see any straight lines, maybe some following the contours of the glass but I think it's just random.
No markings on the metalwork I can find either. It maybe brass but I'm not sure, sorry, not much help am i, lol. I wondered if it could be ormolu?

I've found a comprehensive and illustrated article from Corning Museum of Glass on crizzling of old glass.  ;D

Thank you Chopin-Liszt! How interesting. I'd never heard of crizzling before. So, if his is crizzled it's alkaline not acid that's responsible? Fascinating. I'd assumed its appearance was deliberate but maybe not..
