Offhand, the only article(s) I recall that were team-written by Robert and Paddy, were specifically about the Boshan glass industry. The makers of distinctive millefiori beads—but historically many other torchwork beads and products. Paddy went to Boshan, and was allowed to document their processes. The Boshan industry (and history) was also covered, to some degree, by Simon Kwan in his book, Early Chinese Glass (2001).

I cannot think of an exposition about cloisonné. I will ask Robert if he produced or published one.
