What Is Asbestos?
Many people think asbestos is a modern invention, but it actually (1) has been known for thousands of years. In ancient times it (2) was used in temples for torch wicks and to protect fires (3) lighted on the altars. The Romans used asbestos 2,000 years ago (4) to preserve the ashes of the dead when bodies (5) were cremated. Today the word “asbestos” (6) is applied to a group of fibrous minerals which have the property of (7) resisting fire. From the chemical point of view, asbestos usually (8) consists of lime and magnesia and sometimes (9) contains iron. Science (10) has not found a substitute for asbestos yet. No other mineral we know can (11) be spun into yam or thread. No other mineral can (12) be woven into cloth or (13) made into sheets. Workers in plants who (14) are exposed to risks of fire sometimes wear complete outfits (15) made of asbestos, (16) including gloves, suits and boots.
