Hi Max, and thank you.
If I read that pattern number correctly (853) then it would appear to be significantly later than the two well-known Barolac items on the right of the page. Cannot really assume too much as I notice that the numbers cited for the "Trees" vase is very different to its production number.
This item is 200mm high, and 160mm at its widest point. It does have the classic Inwald mirror-polished base, but no relief or impressed Barolac mark.
Stylistically, this pattern is very different, abstract as opposed to naturalistic. and a major departure from pre-war Barolac patterns. I am suggesting Smrckova, as she arrived as chief designer at Sklarny Inwald n.p. in 1948. This vase has a close affinity with a bowl dating to 1948, from Mstisov glass works, at that time part of Inwald, and also a heavy engraved zodiac bowl from Exbor, both designed by her.
There is a great deal of new information emerging on Barolac, and any interested glassie should have a look at recent editions of PK, at www.pressglas-korrespondenz.de
I should also say, that over-heavy reliance on importer's labels, may be causing confusion. If Weil and other importers labelling, mentioning Barolac was put on all imported items, then it is easy to see why some pieces appear now, attributed as belonging to the Barolac range.
Thanks again and regards,
