Because the glass particles are spherical, they do little grinding on the surface of the workpiece, resulting in minimal contamination of the workpiece.
When used for matte finishing, it produces a beautiful blasted surface. Composition: Na2O-CaO-SiO2 glass
Representative particle size (microns): 125-150
