Well, sometimes things move on quite quickly

In the book BAGUIERS et VERRES À BOIRE du XIXème siècle. Leon Darnis 2014
on page 69,item no 75, Darnis shows a footed bowl (tazza / coupe) which ever word you prefer
in green with white overlay that has an identical foot.
It is identified as 'St Louis vers 1840- 1850' Fluorescence Rose saumon'
http://verrehistoire.typepad.com/files/leon_darnis.pdfI checked out this book, because as I stated earlier in the thread, this goblet has a curious orangey fluorescence. I then came across a paperweight in the book La Cristallerie de Clichy where it was said it had a salmon coloured fluorescence.
Which lead me onto looking into French glass again. Where a reference on a Bonhams auction on another thread gave this book by Leon Darnis. And so ... to an id.
Sometimes it's the smallest detail is all you need.
I've been all round the world as usual. I'm sad it's not Russian, but delighted it is St Louisand c.1840-1850 nice early piece of overlay( and that I had the date more or less correct in my thinking). Wish I'd bought the blue one now. If whoever bought it is reading - here is your id.
Thanks all for bearing with my ramblings
