Unicorne Beads are individually handcrafted in the USA by our network of highly skilled glassblowers. These beads are fashioned in a torch flame by a process called lampworking. Unlike most beads which are made from ordinary or soft glass, Unicorne Beads are created from "hard" or borosilicate glass. Only the finest imported glass from Europe and the United States is used. Many of the colored glass is custom mixed. Borosilicate glass is worked at a much higher temperatures than ordinary glass and then kiln annealed at over 1000 degrees which makes for a stronger more durable product. The higher temperatures are also responsible for the rich natural colors characteristic of Unicorne borosilicate glass beads.
