Glass beads are a commonly used media made of hardened spherical soda-lime glass. They have a uniform composition and stable chemical properties, making them ideal for cleaning, deburring, peening, and descaling. Their nearly perfect spherical shape allows for controlled and unique surface finishes. Glass beads decompose slowly, reducing equipment damage, and can withstand multiple impacts. They are chemically inert and leave no residue on workpiece surfaces.
