Asbestos is the name given to a group of minerals . It usually contains lime, magnesia and sometimes iron. It is dug up from great open pits. It is soft, silky fibers. It can be woven like wool and cotton because it is fiber in form. Asbestos can stand up to temperatures of 2,500C. It is mainly used as an industrial fiber.
In ancient temples the wicks of torches were made of asbestos so that they would not burn away as cotton wicks do. In 19th century it became cheap. The things made from asbestos are boilers, building roofing sheets, fire-resistant and protective clothing. Nearly half of the asbestos products are made in United States of America.

Asbestos can be harmful to health. The fine fibers if inhaled can produce a lung condition called ‘Asbestosis’ (which leads to shortness of breath) and can increase the risk of lung cancer. Demands began to be made that it be removed from some public places, notably schools and even that it be banned altogether. Usage of Asbestos in crayons and toys had been already banned to safeguard children.
