I have the same initial reaction as Westred to Chinese glass. However, I remember touring Chichen Itza with a Mexican tour guide. I was bemoaning the fact that all the many sellers of knick knacks there were selling goods made in Asia. The guide told me a story of a woman who developed a cooperative for a particular type of local craft. The community did well for a few years, and then she noticed that stores they sold to were stopping buying. She found out that a SE Asian company had copied her craft ware and were taking over the market. The stores knew the goods of Asian origin weren't as well made, but the stores also knew that tourists would choose the lower cost item over the "authentic" item. The same is also true of the hand-embroidered Mexican dresses. Tourists, the guide said, simply don't buy the more expensive locally made products. The guide then asked me how many locally made goods I had bought thus far in my trip.
It's a little bit the same in Murano. I looked at the good stuff there, and thought of what I could buy on eBay and in junk stores for the same money. I never thought I could visit Murano without buying glass, but I did. (Well, not quite, I did buy my wife a Venini necklace, but it wasn't for my glass collection.) If a glass fanatic doesn't buy Murano when he's there, what will the casual visitor do? I'm certainly not complaining about the price of modern glass, btw. I think the vast bulk of modern art glass (outside Chihuly) is fairly priced. It's simply that some of the older glass is a fantastic bargain. I look at some of the Zanfirico pieces I've got, think of the work that went into them, and marvel how little I paid for them. But I know I'm not supporting living artists as much as I could, and I worry about that.
So I think there are two issues. People who simply want the cheaper product, buy Chinese, and they're quite happy with it. This, I'm sure, creates a problem for Murano. Then there are people like me. I've got about 450 pieces of glass and four of them were made in the last ten years. (Admittedly, one of them is the most expensive piece I own.) Neither is it that I don't like new glass. Give me a week and a million dollars and I could go crazy in Seattle. For me, it's choice. I've got a limited amount of money, and I'd rather have 450 older (i.e. cheaper) pieces than 20 new (i.e. more expensive) ones. Yet that decision, I'm sure, helps create the market where Chinese glass increases its share of the market, while many other areas where glass is made are in dire trouble. Given the choice, I don't think I would change how I have collected. But neither am I sure that my decision is the "right" decision. I guess what I'm trying to say is that, if there is a problem, we are all, in some way, contributing to the problem.
I think we could have a similar conversation about plagiarism and glass, but I've pontificated enough for a night-- OK, a week.
