— Scratch hardness shows how resistant a material is against scratching or engraving with a sharp object. We are only interested in scratch hardness, not rebound or indentation hardness. We use the Mohs scale for calculating scratch hardness – measured from 1 to 10. For example, you can scratch gold (Mohs scale of 2.3 to 3) with iron (4.5).
