The beads are made from discarded cow horns and bones collected from slaughterhouses. The white bones and horns are stained a dark brown except for the portions of the bead that were coated with a wax that leaves a distinctive pattern on the beads using a “batik” technique. Wax is painted onto the bead to create a design, then the remaining surface is darkened with a vegetable dye. Once the dye is set, the wax is removed. The resulting graphic is reminiscent of the African “bogolanfini” fabric known as mudcloth.
