Where is it used?
Glass Beads; is amineral, non-ferrous , reusable abrasive with a wide range of applications. Due to their (rounded) grain shape, they have a low abrasive effects and are therefore ideal for gentle cleaning. Our customers appreciate the special ability of glass beads to create a silky matte surface finish.
