Large Hole Beads (Greek Ceramic Beads, Glazed Grendinel): Ceramic bead in a loosely formed round shape, Glazed Grenadine, ° 15mm. We use them as spacers. While the color is exceptionally hard to wear off glazed beads due to the high temperature used when firing the glaze onto the ceramic base, glazed beads nevertheless tend to chip more readily than other ceramic beads. Small chips may exist. These are beads with 4mm large holes, very individually shaped--not for perfectionists.
