These are very nice Prosser glass rounds with ridges. Prosser beads were made in a hydraulic press that compressed a cold, moist mixture of finely pulverized materials into cast-iron molds and formed beads ceramic-like finish. They are in a lovely soft pink color. They are made in two part molds, so there is a flat ring around the center.
