Because this group of silicate minerals can be readily separated into thin, strong fibers that are flexible, heat resistant, and chemically inert, asbestos minerals were once used in a wide variety of products. Chrysotile, a fibrous form of serpentine, is also a major source of asbestos worldwide. Asbestos had been used for years as a fire retarding cloth and in brake linings.
