Cryolite - Wikipedia
Cryolite occurs as glassy, colorless, white-reddish to gray-black prismatic monoclinic crystals. It has a Mohs hardness of 2.5 to 3 and a specific gravity of about 2.95 to 3.0. It is translucent to transparent with a very low refractive index of about 1.34, which is very close to that of water; thus if immersed in water, cryolite becomes essentially invisible.

Why use cryolite as raw material when smelting aluminum?
In the aluminum smelting process, cryolite is used as the main raw material for aluminum smelting because: 1. Pure cryolite does not contain any metal impurities with a more positive precipitation potential than aluminum. As long as no impurities are added from the outside during the operation, relatively pure aluminum can be obtained.
