I am sure that many people, when they look at glass, get the feeling that something is not quite right with the appearance of the glass. It is probably our instincts trying to tell us something. The trouble with buying online is that a lot of time the sellers don't have good pictures. Then one has to get the vase in hand before figuring out that something is not quite right.
I've read that many of the Spanish glassmakers worked in Murano for a while, so I guess it isn't surprising that some of the designs made their way to the Spanish borders. I have handled a lot of the Royo/Cire-- pieces and found they were great, but not of Moser quality. The same is true for these 5-spout vases. They aren't soffiati and the sharp edges are not polished out. Still, they are fine vases. I see quite a few of them sold on eBay for respectable money. I think people are more aware of them than they used to be, though, so the prices are not so great anymore. I imagine that knowing about the vases also makes people a bit shy about investing in the real Venini pieces.
After seeing a few of the real Venini and a lot of these copies, it is pretty easy to select the Venini pieces -- that is, if all the good quality ones are really Venini. I am glad that the auctioneer listed his Gordiola (correcting the Gordiole) vases. I believe he solved a big mystery. I had wondered if the vases might still be Murano, just not Venini. Now I know what they probably are.
