by rubbing the mineral on a rough hard surface
Using very expesive test equipment which does all the optical calculations for you.

The minerals that make up a rock determine how fast it weathers to a large extent. This is mainly true when it comes to chemical weathering.

Yes! Pure distilled water is an insulator. it is the minerals, alkali's and acids in the contaminates that determine the resistivity of water!
first you have to determinate in witch step of the process you gett the birefringence. Usually it is in the molding of layer-0
A birefringence is a splitting of a ray of light into two parallel rays of perpendicular polarization by passage through an optically anistropic medium.
There are no exacting standards to determine the value of minerals
The color and type of feldspar minerals largely determine the color of a particular granite.
Temperature and the way it was weathered.
Birefringence is when a material is able to refract light in two slightly different directions depending upon the angle of the light coming in. Crystals if calcite can be shown to do this.
These minerals are quartz, feldspar, mica, and usually hornblende.
it is by weight or heft them
