Large Hole Beads (Greek Ceramic Beads, Copper Patina): Ceramic bead flat discs or washers, Copper Patina, ° 6mm. We use them as spacers or end beads before the bead tips. These ceramic beads, Copper Patina are exceptionally hard wearing due to the high temperature used when firing the Copper Patina onto the ceramic base. In addition Copper Patina beads are very heavy and impossible to break. These are beads with large holes, very individually shaped--not for perfectionists.
