Abrasion characteristics of any material are a function of hardness, concentration and particle size. Hardness is typically measured on the Mohs scale, where a diamond is 10 and talc is 1 (Figure 1). A higher Mohs hardness will scratch or abrade a material with a lower number. Calcium carbonate is a soft mineral with a Mohs hardness of 3.
