Garden Roller and trade beads from Mapungubwe

Garden Roller beads were manufactured first at a site in Limpopo called K2. They consist of large (10-14 mm diameter; 7-15 mm long), mainly barrel-shaped beads. They were made by smelting other glass beads and forming new large ones in single-use clay molds (Wood, 2005:45-49).
Garden Rollers appear mainly in shades of transparent to translucent blue-green to soft green.
