 Manufacturing of the powder glass beads is now concentrated in West Africa, particularly in the Ghana area.The origins of beadmaking in Ghana are unknown, but the great majority of powder glass beads produced today is 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.
