So just following this up as things occur to me.
1) On page 57 of Charles Hajdamach's British Glass 1800-1914 it shows colour plate 4 including this bowl seen in the V&A link I gave earlier.
It's photographed against a white background so a little easier to see the 'real' colour and it appears as a yellow colour glass (in my opinion the yellow is quite clear but leaning towards slightly honey coloured yellow rather than citron if you can picture it). Described in the caption as '... the bowl in yellow glass, ...'
On page 54 talking about this colour plate and bowl, and as part of a suggestion that England, France and Bohemia were all experimenting with colour technology at around the same time period rather than England lagging behind, it says:
'
Stunning proof which underlines this theory is found in a set of finger bowls in yellow glass comparable to the 'Annagrun' or yellow-green colour, achieved with uranium, which had been discovered by Josef Riedel in Bohemia in the 1830s. The finger bowls and matching plates in clear glass, partly frosted and engraved, were used at a banquet in the Guildhall for Queen Victoria in 1837 to celebrate her first official visit to the City of London.'But there is definitely no mention of a maker in the description in CH British Glass pg54. So I'm not sure how this is 'proof' that the English were experimenting with coloured glass at the same time a Bohemia and France really.
2) The mismatch between the uranium yellow bowls and the clear glass plates:
The clear glass plates are engraved with roses and leaves (from the picture on the V&A) and the yellow bowl is described on page 57 as being engraved with roses, thistles and shamrock. I've downloaded the photograph of the yellow bowl from the V&A site and it's incredibly hard to see the engraving because of the way it's been photographed, so I cannot see any roses on the bowl (but I can see leaves which do look similar to the leaves on the clear plate). So I can only clearly see thistles and shamrock on the bowl although the roses might be on the sides unseen in the photo. It's hard to see whether both have been done by the same engraver but the VR insignia looks slightly different to my eye on the two pieces and on the plate it has a small bower of leaves and forget me nots underneath whereas that bower is not on the bowl under the insignia.
3) Neither the V&A or CH describe this bowl as Topaz but I think, whilst the link the Museum of London print site of the bowl has disappeared suddenly, it was described there a Topaz glass,because a link to that description and the bowl still comes up on another print site called Memory Prints here (and gives credit to the Museum of London):
http://www.memoryprints.com/image/142383/james-powell-and-sons-whitefriars-ltd-finger-bowl-in-topaz-glass-1837CH describes it as '
yellow glass comparable to the 'Annagrun' or yellow-green colour, achieved with uranium, which had been discovered by Josef Riedel in Bohemia in the 1830s'.
The V&A describe it as '
Uranium-yellow glass, cut and engraved' and say it was made by Davenport's
https://www.vam.ac.uk/blog/museum-life/seeing-more-glow-in-the-dark-glassThe use of the term Topaz glass to describe this bowl is interesting because Harrach made 'gold topaz' before 1835. In Farbenglas II (Neuwirth) page 278, it says '
Harrach certainly made the "gold topaz composition" already before the Vienna Exhibition of 1835, when the table candlesticks in this colour were also shown'.
and further on in the paragraph
'
A sugar water centerpiece in "gold topaz composition" was part of a presentation by Harrach in Vienna in 1839 (Vienna, 1839; Report, 1840 p. 38).I'm not suggesting that Harrach's 'gold topaz composition' was uranium glass. Just that it's interesting that the name 'topaz' was linked to Harrach before 1835 and was, I think, used to describe that VR bowl by the Museum of London. Why would they have used the term 'Topaz' as a descriptor?
The use of uranium in colouring glass is also according to that same book, known before 1835 in Bohemia (lots of examples given) and the book says the term Anna-green was used by Blaschka before 1835 - so the book questions whether it can be linked to Anna Riedel since it was already in use before 1835 elsewhere - source, Farbenglas II
Walthreud Neuwirth pp.277 under section 'On the history of uranium glass'.
I'm not aware of any other uranium yellow English glass from c.1837. Are there other items out there? It would be curious if this was the only surviving piece.
