CRYOLITE KRİYOLİT - Know More
An interesting fact about cryolite is that when the colorless variety is immersed in water, it becomes invisible This is because it has a refractive index that is very close to that of water There once was a large deposit of cryolite located on Greenland s west coast, but by 1987, it was depleted...
