Topic: Baccarat unusual vase any ideas on date?

there is I think some explanation here on page 10 of why there was crizzling in opaline glass

It is in the right hand column of text.

The uranium is the date restricter, so I doubt your stand is earlier than 1860ish, so as I said late 1800s

Hi Christine
Bohemian glass contained uranium from 1830 although it was being experimented with pre 1790 and baccarat followed suite in 1843. 
Uuranium glass has been traced back as far as 79AD.

So it would be difficult to say uranium was used post 1860.

That's what makes glass so interesting you just never know.

All best Chris

Maybe but not in cloudy green. It was first used mostly as a canary yellow colorant. Green and amber came later. It was also extremely expensive until large uranium deposits were discovered in the USA in the 1880s. Roman glass deliberately containing uranium is also rather suspect. There has only ever been one sample found and that has only been tested once. Other Roman glass colorants have persisted throughout history. Uranium oxide wasn't discovered until 1789. Wanting it to be early does not make it so. I collect uranium glass and wouldn't claim to have anything earlier than mid 1850s and that is in canary flint

Very subjective we can only go by what we read, but that's not always accurate if at all in some cases.  The green on this piece is more of a pastel green similar to the early yellow more transparent as opposed to a solid colour.
Not saying my piece is exceptionaly early but thinking about it if it sits around 1860 means it is 150+ years old.  I think in my book that's old and lucky to survive intact.
Then if you read apparently uranium was ceased pre/ just post WW2.  But I have had pieces of Bohemian glass circa 1970s which contain uranium.  So it makes you think!  Where are people getting there information from.  Books tell you or give you an idea who made the glass but the actual chemistry used to produce the glass is rather lacking.
Still all intetesting stuff.

Cheers Chris

Das Bohmische Glas Band III pp 53,illustration III.51

a trumpet vase with a remarkably similar 'pineapple' knop in the stem.  Along with a remarkably similar gilding bands decoration and foot.  It also has a dark blue snake on it.  But it is so similar in design elements I would say that it is very possible your vase came from Neuwelt.
The vase in the book is 'Alabasterglas',which means it is white opaline as a description of what it looks like.  The snake is cobalt blue.
There is no green on this one but the date is 1855-1860.
There are two further Neuwelt green vases on page 55.  They are dated c.1860. But they are very different in design.

Two pieces in white and green opaline from Schachtenbach on pp161 dated c.1860.

It's in German.
Not available to view on the net but the book is available to buy I guess.

Yes quite an expensive book m.

Have a look at the art work on this vase.  The condition is exceptional there is hardly any rubbing whatsoever.

I think you'll like it.

I think some uranium stocks were confiscated in the 1940s and there may have been a short period when little or no uranium glass was produced, but then little coloured glass of any sort was produced anywhere during WW2 because of lack of access to colorants and luxury goods tax reasons. I have uranium glass from about 1850 right through to 2017, but I would say nothing from the 1940s
