Sorry, I should have been clearer.
Problem with rushing to post with a slow connection.

The old ones are the kind he used to give the glass workers as the sample to make the new beads.

OTOH, this seller also talked about using old bead material to make thenew beads. I've heard that from a number of people very closely involved with the making of the new beads in Bali and Jave. (The baru antiques as they like to say here. Baru means, simply, new.) It makes no sense to me. There is a faint possibility of using old glass but to crush old bead fragments makes no sense. Last year we heard that some particular colors were made with old glass and the rest new but that again does not make sense with the problem of incompatibility.
