The document discusses various properties that can be used to identify minerals, including: 1) Appearance properties such as streak (color of powder when scraped), luster (how it reflects light), cleavage (breaks into flat surfaces) and fracture (jagged breaks). 2) Other properties like density (mass to volume ratio), hardness (resistance to scratching on Moh's scale), fluorescence (color under UV light), magnetism, and acid reaction (bubbles if carbonate in acid). 3) Examples are given like gold being denser than pyrite, the Moh's scale ranging from 1 to 10, and carbonates bubbling in acid due to carbon dioxide gas.
