Chrysotile is a fibrous serpentine mineral, from which comes most of the world's supply of asbestos. Serpentines are hydrated magnesium silicates (3MgO.2SiO2.2H2O). The variety called chryostile has crystalline tubular fibers that are particularly suitable for spinning and weaving heat-resistant fabrics.
