The earliest powder glass beads on record were discovered during archaeological excavations at Mapungubwe, in present-day Zimbabwe, and dated to 970-1000 CE. In our time, the main area of powder glass bead manufacture is West Africa, most importantly, Ghana. The origins of beadmaking in Ghana are unknown, but the great majority of powder glass beads produced today are made by Ashanti and Krobo craftsmen and women. Krobo bead making has been documented to date from as early as the 1920s but despite limited archaeological evidence, it is believed that Ghanaian powder glass bead making dates further back. Bead making in Ghana was first documented by John Barbot in 1746. Beads still play important roles in Krobo society, be it in rituals of birth, coming of age, marriage, or death.
