I can find one set of Saint Louis goblets with a green 'pineapple ish but not really' knop (ie it is a faceted knop) in opaline green possibly uranium glass, in the stem, that date to 1840-1850 - Les Baguiers, Darnis L. p 159
I can find two bowls on stems with the turned back petalled collar in blue and white that date to c. 1845-1850 pp 57 - same book as above. They appear to be described as 'pate de riz' (should be a hat above the a in pate but I don't know how to do it). But there is something different about the way the edges of the petals are and yours have been cut polished and gilded and I think yours looks more Bohemian in make than French. But I could be wrong!
Do you have reference for the shape dating back to 1790?
I do recall seeing a trumpet shaped opaline vase with a turned back plain rim that I think dated to 1820 where I was surprised it was so early, but I just cannot remember where I saw it and it was only a few days ago.
There is a Harrach very large vase on stand that is green and white that is dated to 1873 iirc.
Isn't crizzling damage?
