Jindrich, thank you so much for passing on this very sad news.
One of the most interesting and innovative glass artists has left us, but, as has been mentioned, the wonderful thing is that he left us with so much to enjoy and to remember him with.
I recall seeing his later work for the first time when I visited the Czech Republic about 10 years ago, and found the simple forms deeply pleasing and very understated. Thank you Mr Vizner for all you left us.
My deep sympathy to you Jindrich and of course to all his family.
Nigel
