It was used by the ancient Greeks, Egyptians, and Chinese as a fireproof material. In the 19th and early 20th centuries, asbestos was used for fireproofing and insulating houses: small asbestos fibers were mixed with binders and compressed into boards, paper, pipe covering, ironing board covers, shingles, tiles, and sprayed onto ceilings. Long asbestos fibers were woven into fabrics for used in brake linings, heat-resistant shields, gloves, and fireproof garments and blankets. Health concerns have limited the use of asbestos since the early 1960s. In the U.S., it was declared a hazardous material in 1986.   Fonte: AAT  http://vocab.getty.edu/page/aat/300011071 2020-09-03 14:31:41
