I'm very excited by something I bought a while back and which I *think* I may now have identified! Having searched through masses of Czech glass catalogues and images, I finally found a vase the same shape and size with a different cut pattern on Jindrich's web album here: PAGE LINK
The one in the catalogue has diagonal cuts, whereas mine has cross cuts. The base of mine is flat and highly polished. The top is cut flat and polished, and has tiny bevels on the inner and outer edges.
Height matches the catalogue at 25cm, but the shoulders of mine appear to be a tad lower than the catalogue version. I've added pics showing the top and the pattern detail, plus 2 shots of the vase side on. The greyscale pic shows the criss-cross pattern more clearly than the other pic.
So, the question is, is mine also Jiri Zouzela for Podebrady? Any help, comments or info most welcome.
Thank you to Jindrich for making his reference material available online too.
