Modern spherical glass beads are produced by spraying molten glass into a partially evacuated chamber. Various sizes of solid and hollow spheres are made ranging from a fine powder to 1/4 inch in diameter. Glass beads are used as fillers in polymers to increase strength and provide sound and thermal insulators.Decorative glass beads have been made since ancient times in Egypt, Rome and Greece. They were often constructed by winding a thin thread of drawn-out glass around a wire. This produces a spiral effect and left a tiny tail where the glass thread was separated from the bead. An alternative method was to take one or more glass rods, or canes, and cut them to the bead size, They were then folded around a wire then fused to make a tube. Sometimes the tubes were stretched to make long cylindrical beads.
