Thank you, Frederick, for the clarification and additional information. I appreciate your kind offer to discuss the subject, but I feel I'd need to know a lot more about Edo and so-called "Edo glass" beads to hold up my end of a conversation. The content of my questions was not the tip of the iceberg of my knowledge about these beads, it is all there is. Unfortunately, my time to pursue outside interests is extremely limited right now and it may be some time before I get back to this. In the meantime, I plan to check in on BCN periodically, make at least a few of the talks Joyce is organizing and continue to ask questions.
