Hi:
I saw this vase here and when you you posted it on the other board. It mystified me, and, because of the lack of response, I presume others felt the same. But here are my thoughts, for what they're worth. It looks more Czech than Murano, the colours the protrusions, the bubbles. However, I haven't seen a Czech vase that looks like it.
My suggestion would be to reply to this thread asking a moderator for it to be moved out of the Murano section and into the Glass section. That way, more people would see it, particularly those with some expertise in Czech glass. I wouldn't start a thread in Murano unless I was fairly certain that the piece was Murano. If it turns out to be Murano, it can always be moved back here.
Good luck.
David
