Between what years was asbestos used?

Asbestos has been used since ancient times. It found its greatest industrial uses beginning in the early 20th century, through about 1960. After 1960, the number of applications for asbestos declined as concerns about its health hazards began to slowly make their way through the scientific, medical and user community. In the early 21st century, asbestos is still used in some countries for a limited number of applications, but agitation for a complete ban continues.
