Thanks both

Ivo thank you for looking in the book, I appreciate it.
Doing a bad google translate on the nightflask and beaker pieces, it says there are almost identical pieces in the 2004 exhibition catalogue to this flask and beaker (my underlining below). I'm pretty confident my plate is from the same maker and time period:
'Lot 132: Nachtflasche mit Stöpsel und Becher Milk Glass Decanter with Stopper and Beaker Imperial Glass Manufactory, St. Petersburg
Description: Kaiserliche Glasfabrik St. Petersburg, wohl Alexander Briullow (Entwurf), um 1840'
'Milk glass. On the wall in colorful painting executed? Harder decorative frieze figures on ancient models. Stand and neck orange accents. Gold Rings min. rubbed. H. 8/15, 5 cm (04,823,017)
Briullow Alexander was one of the most influential interior designers of Russia, which took up the new vital flow of historicism and spread. Influenced by his visit to the excavations at Pompeii, he designed the dining room in the Winter Palace in the Pompeian style. The Imperial Glass Manufactory St. Petersburg Conducted the glass vases made me f? For this space by its design. from Almost identical pieces are displayed in the exhibition catalog Imperial Glass Factory 1777-1917, St. Petersburg, 2004, p 71, No 38'What is interesting to me is:
1) the era of the piece - 1840, early opaline, almost milchglas - it's very exciting to have a piece of Russian opaline glass
2) The fact that the design is put down to the influence of the decoration of the Small Dining Room (Pompeian room) in the Winter Palace by Alexander Briullow (from what I read another designer was in place after him from 1840-1860). And from what I read, the Pompeian design he did for the room seems to have followed, and was obviously influenced by, his previous visit to Pompei.
So if the dating is correct and my plate is Russian from 1840, this makes it earlier I believe, than for example
- the Richardson pieces showing classical designs shown on the Portland vase in burnt orange and white (c.1845-1850 - CH British Glass 1800-1914 page 101) and plate 84 page 113 Sepia enamelled white opaline vase after an engraving by Flaxman
- The Webb's Mr Giller decorated vases in classical Etruscan theme shown in the Art Union Journal 1847
- The Davis Greathead and Green vases (page 137 same book) shown at the Great Exhibition in 1851
It also makes it possibly earlier than all the vases shown on page 136 where the caption says 'Five vases in the Etruscan style, fashionable from 1847-1851....'
if the dating is correct.
In ‘The History of Glass’ Klein,Lloyd on page 176 it says that Russia held it’s ‘first public exhibition of Russian Manufactures, in St Petersburg in 1828-29, …’
It goes on to say Russia held other public exhibitions during the first half of the 19th century -
‘Countries such as America, Russia and France had frequently organised exhibitions of their own manufacturers during the first half of the century, but the Great Exhibition (this was held in 1851), or the Exhibition of the Industry of All Nations as it was officially called, was the first to bring together products from all over the world. Most of Europe’s leading glass manufacturers were represented as well as several from America…. (the one exception was France, whose only representative was Clichy)’.
It doesn’t mention Russia being represented at the Great Exhibition and neither does it mention Russia in CH British Glass 1800-1914.
But I wonder if the influence of all these Etruscan style vases being shown by various British and Bohemian makers came from Russia perhaps? Especially the use of the wide bands of burnt orange colour on the Harrach pieces?
