Not sure if you have this information from this source, i came across it tonight.
British table and ornamental glass by L.M Angus-Butterworth. Published 1956.
"In 1837 a pair of glass girandoles,or branching candlesticks, coloured yellow by a salt of uranium were presented to Queen Adelaide"

I wonder if the reference for these candelabra (L.M. Angus-Butterworth 1956) came from the wording in Harry J Powell's book - Glassmaking in England 1923? I don't have the book but on searching online brought up this:
https://archive.org/stream/dli.bengal.10689.10443/10689.10443_djvu.txtOn page 131 of that book (info from search on the internet) it says:
page 130 ...
'
At the present time there are hundreds of varieties of glass, differing
from each other' in chemical composition. To this list the Whitefriars
Works have contributed a fair share. The advertisement of 1710 refers
to two varieties of flint-glass, “ best ” and “ ordinary ”: unfortunately the
... continuing on page 131
recipes have disappeared, but the two kinds probably differecf in the
quality of sand, or in the proportion of red-lead. Until the hampering
excise regulations had been withdrawn, little could be done towards the
scientific development of the industry. It is, however, recorded that in
1837 a pair of glass girandoles, coloured yellow by the addition of a salt
of uranium to the ordinary flint mixture, were presented to Queen
Adelaide.'In reference to this, as I mentioned in my post here:
https://www.glassmessages.com/index.php/topic,70066.msg391911.html#msg391911it appears from what Barrie Skelcher wrote, that the candelabra were in fact silver with uranium glass droplets and presented in 1836. So perhaps Harry J Powell and Barrie Skelcher were either writing about a different set of girandoles ... or used a different way of describing them, as it seems unlikely two uranium glass sets would have been presented one year after the other?
