I agree with most of what you say, and it was interesting to read. I did try to make it clear that it wasn't about quality or even about it being Chinese. If you just want a nice piece of glass it isn't even an issue.
However, if you collect and you like to know about the pieces you own, or if you have to part with something and you want to be sure you correctly identify it, there's no denying that the fact these pieces are almost identical, and unmarked, makes it very much harder these days than it was ten years ago.
I appreciate that a great deal of glass is already unmarked, but we have learnt to identify them by form and colour. Now that those forms are being "copied", it is getting harder to do that with confidence. Fortunately, most of the glass I have was collected more than ten years ago.
You say that "traditional 'Chinese' culture glass is something that does not appeal to the Western cultures". That would suggest that all western glass is broadly the same type, which is clearly not the case. I feel that we have a history of fascination with Chinese culture and art, and many of the designs on vintage Peking glass, for example, would appeal.
It will be interesting to see what other members think.
