With due recognition of the views of certain members, with regard to commenting on live eBay auctions, I would however like to draw attention to auction number: 6565141456
, for academic reasons.
What we see, is a large, frosted glass vase, press-moulded, with raised scenes of marine life. I have not held this, but the quality appears good, and the design is reminiscent of some Barolac designs. It might therefore be reasonable to assume this is a 1920's-30's piece.
Now compare that image with this one, a piece in my own collection;http://tinypic.com/e7jcdl.jpg
It may not be absolutely obvious, but this image has been taken of the same section of decoration. What I can tell you is that the clear unfrosted vase has very clear mould lines. There is no doubt in my mind that these two vases came from the same mould.
The purpose of drawing these two vases to attention is to ask the question as to whether, the frosting of the glass reduces the prominence of the mould-lines?
If so, then the age of these vases may not be distinguishable, as naturally one might assume that the frosted one is early, the clear, late in the mould's life.
Given that I know the second to be of postcommunist Czech origin, it still carries its original LIBS "Glass from Bohemia" label (the former Libochovice glass-works, part of Sklo Union) is it possible to date the former? I can't tell you whether LIBS makes the same vase in frosted finish now.
Clearly, the return by so many Czech glass-works to resurrecting old designs, is bound to cause even the most expert, to have doubts.
