Halite hardness.

3.2 Halite crystals from the Great Salt Lake, Utah. ... Hardness is a mineral’s resistance to abrasion or scratching. We determine relative hardness (symbolized by H) using a scratch test: we try to scratch a surface of one mineral with an edge or corner of a second mineral. If a scratch or abrasion results, the first mineral is the softer.
