A couple of years ago I was trying to find out about Chinese paperweights and I contacted Hong Bao and asked if they could tell me which glass-houses made the various weights they sold. The reply I received seemed to assume I wanted to cut the Hong Bao company out by approaching the makers direct. They said it was not their policy to identify the makers, but that they would do me a very good deal if I wanted to buy paperweights in large quantities. I wrote again, explaining that I only wished to be able to identify which makers made which weights, but sadly got no further communication from them.
