I am probably diverting this topic slightly - but I think the link here to this piece
http://www.alibaba.com/product-gs/513717074/Wedding_Decor_Antique_Vases_Glass_Mexican.html demonstrates many of the points being made in this thread -
- about the difficulty of identifying Chinese glass
- how derivative some new glass can be
- the larger quantities these pieces can be churned out in
So....this vase on my link is on Alibaba
- it says it is Mexican
- it says the place of origin is Guangdong China
- it says the company is Xiamen Longree Craft Company (Fujian, China)
- but it doesn't say if they made it or just import them to ship worldwide or whether they were the distributor for the glass which was made in Guangdong China (which given it says that is the place of origin might be where it was made) or whether the 'place of origin' actually means where it would be shipped from, which given it also says it is Mexican is confusing.
It says they can turn out 5000 per month, it also says it is 'Chihully'(sic) inspired.
