They look like Iranian faience melon beads to me, see chapter 8, page 74 of Lankton's A bead Timeline. 10th - 11 century BC. If they are glass, I don't know, never seen this type of bead in glass.
Hello Ali.
Are the beads actually giants?
By coincidence, I just retrieved my paper by Eisen on melon beads. I will review what he had to say.
But I think these beads are "not straight" because their manufacture was fast and sloppy.
