Pumice Powder
In the jewellery and silver trade pumice is recommended as a buffing media. This is the first stage of polishing where fine abrasive media like pumice powder is required. Without the buffing the final mirror finish cannot be achieved by polishing technicians.

Fine powders of 250 micron and below are recommended.

Glass Beads
Glass bead blasting produces a clean, bright, satin finish, without dimensional change of the parts. Primarily used in blasting cabinets for honing, polishing, peening, blending, finishing, removing light burrs and cleaning most light foreign matter. 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.
Range of macro and micro grits available.
