see above post.
Also in reading the book Farbenglas I by Waltraud Neuwirth on page 279 and 280 the writing under the Heading 'Chrysoprase Composition' is all about green glass ranging from 1831 to 1857.
After describing many glass items in green made between those dates it continues in the same paragraph:
'Without exception, contemporary glass batches (chiefly opacified glass) contain uranium, mostly in the form of uranium oxide'.
There is no doubt from the way that sentence is written that it is referring to the glass dated of that period and discussed in the same paragraph in the wording directly preceding that sentence.
I am not suggesting for one moment that the OP's item was not made c.1860.
The style and design is similar to items dating around that date.
But according to my books there was uranium opaline glass produced in Bohemian in the 1830s and 1840s.
Having looked around, the foot and stem and the gilding design have some similarities with this set c1840 apparently from Theresienthal/Bayerische Wald. It might be worth looking into a little further as a potential for the maker.
