in the right hand column on page 11 Spiegl lists items shown by Neuwelt at the 1835 exhibition which include toilet bottles,stained green and gilded in chrysoprase composition and goldtopaz composition:
http://www.glas-forschung.info/pageone/pdf/farbglas.pdfI have a toilet bottle in uranium glass I think dates to c.1840. On page 15 he shows two bechers in light and darker green opaline glass and the caption says they are 'Chrysopras-glas'.
There is a transparent yellowish uranium glass bowl shown just described as yellow uranium glass.
Page 17 talks about how difficult it was to produce yellow glass!
on page 18 he says
'During the 1840s, yellow uranium glass (“Annagelb”, “Eleonore yellow”) became a popular fashion colour. Not only souvenir and friendship glasses, but also, to a considerable extent, everyday objects such as bowls, bottles and decanters were made from it. The glasses appear yellow-green when viewed from above in daylight, and light yellow when viewed through. They display a peculiar, changing play of colors, particularly in striking sunlight, which is related to the dichroism of the glasses in ultraviolet radiation. The fluorescence effect is most beautiful in the glasses that have a yellow tint. In the types tinted green with copper oxide, the fluorescence in ultraviolet light is weaker or absent. "Isabell" was the name of a matt yellow opaque glass from the Harrach glassworks that was first produced in 1838 and is probably a uranium color, as was the "lemon yellow bone glass" from this glassworks from 1841. Both colors are very rare. The two terms do not appear in Vinzenz Pohl’s recipe booklet.'
But again, this was 1840s for the yellow uranium glass. Not 1837.
The Queen Victoria bowl in real life to me looked more like my Walsh Walsh tumbler in the pic below.
These were taken in the evening under LED light - rubbish lighting. I actually think the toilet bottle is maybe a lamp and is North Bohemian (source Das Bohmische Glas item with same enamelling) but I don't know which glashutten. It is also much zingier in colour in daylight whereas it bizarrely looks 'citrine' coloured in the photo on white, but all I have in the kitchen at the mo (night) is led lighting
