Hi, well if there is one the same in the museum with the same gilding then that is a good thing to go on
I have looked in the book Das Bohmische Glas band II pages 167-170.
In the book 10 pieces are shown under the heading Bunte Hyalith- und Agatinglaser.
One piece is green, one is cream and the others are all shades of purple.
All have a cut angular foot as opposed to a curvy ribbed foot such as your piece.
What they all seem to have in common is that they are quite opaque and thick and some look very slightly streaky to me, although it's difficult to tell from the photos. I would have thought that might be why they were named 'agatinglas' i.e. agate like?
One piece has that gilded star motif in a decorative band, the same star motif as your piece. page 167 left hand becher.
They are all dated c1834.
I suppose what I am thinking is maybe yours is made by Buquoysche Glashutten but would not be called Agatinglas? and that maybe stylistically it's a little later than 1834? It's less angular than the pieces shown, perhaps the style moved on a little?
And would yours be called Opaline glass rather than Agatinglas if you see what I mean?
I'll keep looking through the book and see if there is anything similar in style as well. I couldn't see anything else in this beautiful purple colour from any other make than Bucquoysche Glashutten though.
Yes the French did make beautiful coloured opaline glass including a colour called 'gorge de pigeon' which was a beautiful purple pink colour.
