  ' I wonder if it was known how to produce uranium glass  in Bohemia prior to 1840  .... but not in England.'


With reference the date Harrach started producing lead glass and also their production of uranium glass:

The Legend of Bohemian Glass, Antonin Langhamer, TIGRIS Czech Republic 2003
 - page 79

re Harrach

'At a Prague Exhibition in 1828 the glassworks boasted the first lead - or "ringing" - crystal in Austria.'

and

'They imitated Egermann's ...., made uranium glass containing some alabaster under the name "Chrysopras" (1831), and later perfected a uranium yellow glass.'

  Information given in the preceding post of much value I think, as it is some what specific to the yellow [canary] version of uranium glass v.s. the green version. This is exactly the type of information I have been looking for. Many thanks....The green version may have been a easier go, the opaques possibly more popular.

Thanks Cagney - I have seen the image and have the Book Das Bohmische Glas Band II so some are in there in very close up which is great.

Here should be a better link where you can see more of the detail of some of that uranium display in the link:

Dated 1830-1850 which is difficult given I want to know what was produced 1830s

As a complete aside, I have a mirror that appears to be very similar construction/design of the mirror photographed in that link.

I've always wondered where ours might have been made.  Although bought in a junk shop  I assumed at the time it was fairly contemporary to when we bought it i.e. 1990s. and to be honest I'd assumed made in China for Laura Ashley or something.
Never looked at it that closely and it's very big and too heavy to get down to look at. Still think it's a newer piece but
 I wonder if mine was made in Czechoslovakia. Would be nice if it was

There are plenty similar on Wayfair now:

This photo should give you the whole display case of uranium glass I think:

Cagney you may (or may not) find this interesting.
It's about Gold coloured glass and Topaz coloured glass - comes from a publication dated 1816.  No mention of uranium of course.
Encyclopaedia Perthensis Vol X  1816 Printed by John Brown

https://www.google.co.uk/books/edition/Encyclopaedia_Perthensis_Or_Universal_Di/0wFQAAAAMAAJ?hl=en&gbpv=1&dq=gold+topaz+glass&pg=PA483&printsec=frontcover

See page 481  under No.12 Gold colour

and page 483 under No. 20  Topaz.

With reference the purple small flasks:
See page 482 under No. 16 Purple

Very interesting piece of glass here:
https://bentleypriorymuseum.org.uk/bentley-priory-collection/queen-adelaide-perfume-bottle/

The Bentley Priory museum says it was produced by Apsley Pellatt c. 1830 probably as King William came to the throne, for Queen Adelaide.
Interesting because it is, in their words 'yellow', cased glass. 
It appears to me to be clear glass with a yellowish overlay (topaz?) cut to clear.  i.e. cased glass. I think 1830 would be quite early for cased glass?

  The complete showcase of uranium glass at Passau very illustrative of the depth and diversity of color to be had. I see how the terms canary, topaz, etc. can be subjective, interpretive and even interchangeable. As you sort of intimated at the beginning of this thread, one persons canary can very well be another persons topaz, I did come across some of Pellats recipes for colored glass collected by M. Drake  sometime between 1851-1874. Of note is the last entry from the table of contents.

  The crown if actually plated/cased  with yellow glass a small ' Tour de Force'. I wonder if the yellow may be a silver stain [ not silver color, silver in the stain batch to get the yellow].

Well now ... funny you should say that.  My absolute first thought on coming across it by accident was 'made by Neuwelt, stained either at Neuwelt or by Egermann'.
I investigated what I'd recalled in the book:
See page 109 of From Neuwelt to the Whole World, plate 115 -  for a 'Flacon in the form of a crown' which indeed is very, very similar and has a Maltese cross for a stopper.
The 'turban' cutting around the foot is something Harrach used, seen on many items in the book,  and iirc it's specifically mentioned in the book.  I'll try and find the quote.

see my reply above and I've not yet found the 'turban' cut reference in the book but there is a specific reference to these crown shaped articles because not only did they make them in Flacons but also as lids for goblets.  I wonder if I read the reference to that style of cutting somewhere else - maybe W. Spiegl.
Page 96 From Neuwelt to the Whole World - discussion of lidded goblet plate 89 with crown shaped lid

'... The most eleborate cut ornament is on the goblet lid, which is composed of two parts: the lower arched section, cut right through, and the removable handle  in the form of a sphere and a cross.  In cutting right through the glass (piercing of the exterior of objects also appear in flacons in the shape of a crown) - a technique that was one of the most difficult in glass-cutting - Neuwelt was a leader among European producers of decorated glass.'

Thank you for this
I've seen the reference list in books of the period but I'm not sure where, and certainly not seen the original handwritten item.
