although I'm sure known far more commonly as 'Curved Star' - a name provided by the carnival glass collectors. I've posted here as Glen Thistlewood has commented previously on this pattern - ""Different variations of the Curved Star pattern were made by Eda Glasbruk (Sweden) and Karhula (Finland) however there are very significant differences. In my opinion, the vast majority of Carnival Glass items found in the Curved Star pattern were made by Brockwitz.""
I've really no idea if these differences apply also to non-carnival pieces, and Raymond Notley has commented that - "Brockwitz was a major mould-maker and sold this pattern to other factories" - thus suggesting that this design might have multiple origins, but in view of Glen's advice then more likely perhaps in non-carnival only?
I was aware of this pattern in carnival, clear, blue and red, although don't recall seeing a picture of a blue example - maybe blue is less common - so here it is. Height of these two c. 170 mm (6.5/8") - with the blue piece being noticeably crisper and a little more refined. Both show reasonable wear so I'm assuming some reasonable age - perhaps pre 1940 possibly, but only guessing.
Brockwitz started production in 1904, and the earliest catalogue known to show this pattern is 1915 - the same year I believe that they started carnival.
If anyone has suggestions of makers of plain red, blue and clear examples of 'Zurich', other than Brockwitz, it would be interesting to know.
Regret I'm not clever enough to have researched the above, so offer a big thanks to Glen and Stephen Thistlewood, Siegmar Gieselberger, and to Pamela for making available on the GMB Dieter Neumann's massive work on the factory catalogues.
