This one really puzzles me...
Very tall (43 cm) vase, blue and amethyst glass. Flat polished base, edge of the base not bevelled but perfectly smooth (fire-polished?).
Colours would fit with Czech glass from the early 1960s (see the comparison to a Stahlikova ashtray), but I cannot find anything in the Skrdlovice pattern books. Another Czech contender would probably be Chribska / Hospodka. The base finish would be a little unusual for Czech glass from that period, though.
It does look vaguely similar to some Adam Jablonski pieces, too, but I think the colours are completely wrong.
Due to the base I am even considering Murano...
Or maybe I should look much further east?
Thanks for any lead!
