The chevron bead is arguably one of the most, if not the most, popular bead of all time.
First invented in about 1500 by the Venetians, they continue to be produced today. Chevrons are a specialized cane or drawn glass bead.
They are formed by blowing a single or multiple layers of glass into a tapered mold with corrugated glass, thus producing the points on its outer surface.
This pleated gather is subsequently encased with additional glass layers of the desired colors, which may again be molded to produce further outer layers with points.
Still viscid, this multi-layered, hollow gather is then drawn into a cane of at least six feet, cooled, and finally sectioned into beads.
