Anik, you're not alone in being thrown out of a store.
I was in Murano last month and saw the window display in the photo below. It took a minute to register that the pieces were all Skrdlovice/Beranek by Vizner, Palecek, Hora, and others. I went it to the store and, pointing to the display, asked, in what I hoped was an incredulous voice, "Murano?" The owner said all the pieces in the window were designed by his uncle, Giacomo something.
I happened to have my iPad with me and opened it to show him a Vizner piece the same as one in the window. "All your pieces are Czech," I said. He came back: "No, no, my uncle designed these in the 1940's The Czech and Chinese copied him."
I told him that he was a disgrace to the Murano and Czech traditions. He then told me to leave the shop. Best guess is that the glass was remaindered when Beranek closed.
Other than that, Murano was lovely. I had a great two hours in Venini where the salesperson could not have been more helpful even although I made it clear that I wasn't buying. She brought out old catalogues and pieces, and was happy to chat about the glass. Even shook my hand when I left and thanked me for coming in. Also directed me to the Carl Scarpa exhibition that was just opening on San Giorgio. Spectacular. Great new book on Scarpa, too.
PS It's good to see that you've all been busy keeping the Skrdlovice market afloat while I was on holiday. I've got a couple new Skrdlovice pieces on my Picasa page, if anyone is interested.
