While trying to identify this vase, I came across an old topic of 2005 by Ivo where a noughts and crosses vase was described as by Jan Schmid, Libochovice, 1964.
http://www.glassmessages.com/index.php/topic,3220.0.html. Unfortunately the accompanying picture was no longer available in the thread. I tried the Sklo CD of Marcus Newhall, but no Schmid designs of 1964 for that company were in the database. To be sure I looked at those ingredients seperately, but nothing identifyable turned up.
Also, my vase is 22 cm high (and 6 cm diameter at the base, 8 cm diameter at the widest point of the top) which makes it higher than the 17.5 cm of Ivo's vase. It is a very nice quality, though, and it was described at the sale as Czech of unknown design and factory (which proves nothing, I know).
Anyway, I'm not sure this is the same vase. Ivo, could you have a look for me if it looks like yours, or if this is a different one? And if it is a different one, does anyone have more info on it?
