It seemed to me that this particular bead was too uniform to have been made entirely by hand, and it had dished-in depressions on either end that appeared to be just like the molding depressions on Prossers. But under the microscope, I can clearly see the edges of the fused glass particles inside the holes.
So of course you are correct - a fully powder glass Kiffa! Thanks for the beaducation on this one!
