Properties that require a tool:

  • Hardness (often measured using a tool like a Mohs hardness scale or scratch test)
  • Carbonate content (can be tested using chemical tests)

Properties that do NOT require a tool:

  • Cleavage (can be observed by visual inspection)
  • Luster (can be assessed by looking at the surface of the mineral)
