Mohs Scale - Typical Materials.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.

Halite has weak hardness (Mohs scale 3) and, under quite moderate pressure, rock salt flows much like ice. The dry Zagros Mountains (Iran) feature some notable salt glaciers.
