It is often useful to first determine if a mineral has a metallic luster. A metallic luster means shiny like polished metal. For example cleaned polished pieces of chrome, steel, titanium, copper, and brass all exhibit metallic luster as do many other minerals. Of the nonmetallic lusters, glassy is the most common and means the surface of the ...

Next, the composites and the materials used to produce them were examined to determine the specific surface area. Subcritical N 2 (77 K) gas adsorption measurements were carried out with a Micromeritics ASAP2020 instrument (Norcross, GA, USA). Before the analysis, 0.3 g of dry sample was degassed in a 60 min measurement at 363.15 K to …

These physical properties are useful for identifying minerals. However, they are much more important in determining the potential industrial uses of the mineral. Let's consider a few examples. The mineral talc, when ground into a powder, is perfectly suited for use as a foot powder. It is a soft, slippery powder so it will not cause abrasion.
