Q: How strong is a mineral?
Hardness: A mineral’s strength is determined by the Moh’s Hardness scale, where a mineral is ranked relative to other minerals and objects of known strengths. The scale is written from 1-10 and is logarithmic in nature; however, the way we usually evaluate a mineral in the classroom is by whether you can scratch it with your finger, if it can scratch a penny, and/or if it can scratch glass.
