On the topaz-coloured glass: What is meant by 'topaz-coloured' ? (see Examiner list of items for the 1837 banquet noted at bottom of post)
On the description given below I'd assert that the uranium glass bowls shown in the V&A and Corning do not meet the definition of 'topaz-coloured glass':
Topaz glass - taken from The Practical Mechanic and Engineer's Magazine Vol IV 1847 from an article taken from the Annals des Mines 1843:
Page 266 - Under the Chapter Heading 'Chapter VIII - Of Coloured Glass'
Quote:
'Yellow There are five distinct yellows:-
1. Topaz-yellow - prepared with charcoal dust
2. Antimony yellow...
3. Orange-yellow...
4. A peculiar-yellow...
5. Greenish-yellow - this colour provides a fine effect in daylight; by candle or gas-light it appears of a dirty yellowish-white. It is prepared with the yellow oxide of uranium of commerce; but as this material always exhibits traces of the presence of iron, the yellow glass made by it always presents on the edge a light greenish tint'

'The Examiner list:
'The decanters, claret jugs, champazne, hock and other glasses, were all richly cut, and ornamented with a vine border, varied with the rose, thistle, and shamrock, and the Royal arms. The supply for Her Majesty's table consisted of three dozen wine glasses, three dozen small claret glasses, three dozen large ditto, three dozen champagne ditto, two dozen liqueuer ditto, two dozen goblets, two dozen carafes and tumblers, two dozen hexagon massive decanters, one dozen claret ditto, 18 wine-glass coolers, two dozen topaz-coloured hock glasses, six water jugs, one dozen topaz-coloured finger glasses, two dozen ice-plates and four antique earthenware jugs with the Royal and city arms in relief.'
(the rest of the Examiner list for the general entertainment glass is the same as the Birmingham Journal and also only mentions 350 wine glass coolers.)'
Just came across something which might help regarding what is meant by 'topaz' coloured:
From Walter Spiegl
Farbige Gläser
http://www.glas-forschung.info/pageone/pdf/farbglas.pdfScroll down to page 30 under the Heading 'Rosa Rubin und Topas-glas
'
Mit dem Goldrubin verwandt ist das »Topasglas«, das man in Neuwelt schon 1829
herstellen konnte und bei Lötz und Schmidt in der Goldbrunnhütte etwa seit 1830.
Neben der Goldauflösung wurde der Schmelze eine kleine Menge Antimonoxid
beigegeben, das dem Glas eine rötlich gelbe Färbung verleiht.'using google translate this says:
'Related to the gold ruby is the »topaz glass«, which was found in Neuwelt as early as 1829
could produce and at Lötz and Schmidt in the Goldbrunnhütte since about 1830.
In addition to dissolving the gold, a small amount of antimony oxide was added to the melt
added, which gives the glass a reddish-yellow color.'
So - was the set of topaz glasses referred to in the list quoted above actually a reddish yellow glass rather than a uranium yellow glass?
If it was, this might preclude these uranium glass bowls in the V&A and the Corning from being part of the ' one dozen topaz-coloured finger glasses' in the list quoted above?
The becher in this link mentions topasglas so could be the kind of colour referred to perhaps - the seller has this listed as dated 1836:
