[10] The Pennsylvania Salt Manufacturing Company used large amounts of cryolite to make caustic soda at its Natrona, Pennsylvania works, and at its Cornwells Heights, Pennsylvania, Plant, during the 19th and 20th centuries. As natural cryolite is too rare to be used for this purpose, synthetic sodium aluminium fluoride is produced from the common mineral fluorite. The name is derived from the Greek language words κρυος (cryos) = ice, and λιθος (lithos) = stone. Cryolite (Na 3 AlF 4) : It increases the conductivity of mixture and lowers the m.p. 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.[6].
