Fire Polished beads are glass beads that are faceted by machine. The edges and surface are then given a softer, polished look by placing the beads in hot ovens or over open flames. By virtue of this process, Fire Polished beads are all slightly different from each other; this adds to their charm. Unlike Austrian faceted crystals, Fire Polished beads contain no lead. It is the heat polishing process that gives them their soft glow and brilliance. Colours may vary from dye lot to dye lot, so it is best to buy sufficient beads for your project all at one time. Colours may appear darker and more intense in larger beads, and softer and more translucent in smaller beads.
