You would have to have some compelling evidence that ANY Boshan lampwork beadmakers had any typical trailing skills, in the period we are dealing with. I have determined that their skills were very rudimentary. They knew how to add crumbs, drizzle trails, occasionally comb trails—and that's about all, apart from dropping on murrine where they wanted them placed; and the unusual use of equatorially-applied ritorte or filigrana canes.

These is no evidence for Venetian-like nor Japanese-like trailing in Chinese beads—even those from Boshan. The Chinese only learned to perform typical trailing strategies about ten years ago.

If you can, please show an example of a bead that you think has a trailed design rather than a cane design. JDA.
