How the Mohs Hardness Scale Works. To rank a mineral's hardness, mineralogists scratch its surface with another mineral of known hardness. If it scratches the surface, it's harder; if not, it's softer. For the in-between cases, they work their way up the scale. The Mohs scale is a useful tool for quickly identifying minerals in the field.
