We were discussing techniques. The traditional (and still practised) technique for making Maure pg beads/"Kiffa" beads/Murakad is the so-called wet core powder glass technique. Apart from the beads discussed, which are manufactured in said technique there are other, equally authentic beads, that were not manufactured in the wet core powder glass technique. Your post shows one of these. These are beads where "foreign" "cores" were used instead of wet core powder glass cores.

I've noticed at the beginning of this thread, and on occasion of several older posts on this topic, that you describe these beads as "bottle glass" beads, particularly in cases where the glass "cores" are partially exposed. In the post I am replying to here you also call these types "bottle glass varieties which were made from reground Czech "Vaseline" beads". However, it can only be the one or the other: prefabricated bead core or bottle glass core. On closer scrutiny of your "bottle glass" varieties you may notice that the great majority of these has prefabricated bead cores, and not cores made from actual bottle glass.
