Anne, a few years ago I did a series of blog posts investigating Chinese cloisonne beads. Here's a link to a post contrasting Chinese and Japanese beads, with a link to the Beads: Journal article that Fredric Schneider helped we write on the history of Japanese cloisonne beads.

Once upon a time I actually corresponded with Josh Chamberlain about a large Chinese vessel that appeared to be a good copy of a 19th century piece. His online nickname of "Juice" is a good choice, I think, LOL.
