These are relatively early recent bead production from the beginnings of production of huge numbers of handmade furnace-wound opaque glass beads in India!
They most likely have large holes with a black residue?

We sold them by weight in my shop in Portobello Road, London in the early '80s, and I bought them from a small importer by the Kilo. I so miss them now!

Yours have an extra refinement of being slightly combed or dragged.
