These great beads are made by the Krobo People of Ghana, Africa. Powder glass beads are made by crushing glass to a fine powder and heating it so that the particles fuse together. The glass is then poured into clay molds, with a cassava leaf stem used to make the hole. They are baked in an oven and the glass fuses and the cassava stem burns up. This technique has been used in Africa for centuries.The new stock may have a touch of green.
