Glass Beads for Gentle Blasting and Silky Matt Surface Finishing

Glass beads are a mineral, iron-free and reusable blasting abrasive designed for applications where a clean, controlled and comparatively gentle surface treatment is required. Thanks to their round grain shape, they produce a low abrasive effect and are particularly suitable for delicate cleaning, deburring, finishing and surface refinement.

The material is especially valued for its ability to create an even, silky matt surface finish without aggressively removing the base material. This makes glass beads a reliable choice for fine blasting work, reusable abrasive processes, filling bead applications and reflex glass bead use.
