  • Abrasive Selection: Performance and Quality Considerations

    The hardness of the abrasive will affect the rate as well as the effectiveness of cleaning. Hard abrasives will cut more effectively and effi- ciently than soft or brittle abrasives. Hardness is measured by the Mohs Scale, which ranges from 1 to 10, with 1 being low or the softness of talc to 10 being high or the hardness of a diamond (Fig. 1).
