Glass beads are manufactured from lead-free, soda lime-type glass, containing no free silica. Glass bead blasting produces a clean, bright, satin finish, without dimensional change of the parts. Glass beads are primarily used in blasting cabinets for honing, polishing, peening, blending, finishing, removing light burrs and cleaning light foreign matter. Is also widely used for glass etching projects where a smooth finish is desired. For delicate thin-walled parts and thin welds, peening with glass bead abrasive material provides the right balance of stress relief without over-stressing and causing damage. Glass bead can be reclaimed and is most likely to be used in a blast cabinet. Best uses: paint & coating removal, surface preparation, removes carbon, rust, and corrosion from aluminum and steel and glass etching. A light, low-dust abrasive. U.S.A.
