Mineralogists have special terms to describe luster One simple way to classify luster is based on whether the mineral is metallic or nonmetallic Minerals that are opaque and shiny such as pyrite have a metallic luster Minerals such as quartz have a nonmetallic luster Luster is how the surface of a mineral
Only soluble minerals have a taste but it is very important that minerals not be placed in the mouth or on the tongue you should not test for this property in the classroom specific gravity specific gravity of a mineral is a comparison or ratio of the weight of the mineral to

Jan 23 2020nbsp018332mineral densities as a general rule nonmetallic minerals have low densities while metallic minerals have high densities most of the major rockforming minerals in the earths crust like quartz feldspar and calcite have very similar densities around 26 to 30 gcm 3 some of the heaviest metallic minerals like iridium and platinum

Specific gravity specific gravity g is defined as the ratio between the weight of a substance and the weight of an equal volume of water at 4 176c 39 176f thus a mineral with a specific gravity of 2 weighs twice as much as the same volume of watersince it is a ratio specific gravity has no units

Dec 13 2016nbsp018332specific gravity also known as quotrelative densityquot is the ratio between the weight of a stone in air and the weight of an equal volume in water by convention the temperature of the water is 4176 c and at standard atmosphere because the density of water is greatest under these conditions
