The identity of the person who discovered asbestos is lost in antiquity. Although it's most extensive use began in the early 20th century, the mineral was known and used to a limited extent for centuries.
Asbestos has been used by humans for thousands of years, but its mineral form was first identified by geologists and scientists in the early 19th century. The name "asbestos" is believed to have originated from the ancient Greek word meaning "inextinguishable" or "unquenchable." The mineral's fire-resistant properties made it popular in various industries, despite its health hazards only becoming widely recognized much later.
The only way to definitively determine if old tiles contain asbestos is to have them tested by a certified asbestos inspector. Asbestos was commonly used in tiles before the 1980s, so if your tiles were installed before then, there is a higher likelihood of them containing asbestos. However, visual inspection alone is not enough to confirm the presence of asbestos.
Asbestos was banned in sheet materials in the United States in the late 1970s. The use of asbestos in sheet materials has declined globally due to health concerns associated with asbestos exposure and regulations restricting its use.
Asbestos is mined in various countries around the world, including Russia, China, Brazil, and Kazakhstan. The largest asbestos mines were once located in countries like Canada, South Africa, and Australia, but many of these mines have now closed due to health concerns associated with asbestos mining and use.
US Gypsum last used asbestos in their products in the mid-1970s. Following increased awareness of the health hazards associated with asbestos, the company ceased its use in manufacturing due to regulations and lawsuits related to asbestos exposure.
Asbestos was commonly used as a component in building materials, including plasterboard, before its harmful health effects were well known. However, most modern plasterboard does not contain asbestos due to safety concerns. It's important to check with a professional if you suspect that your plasterboard contains asbestos.

Asbestos (particularly blue asbestos)
An asbestos square is a square of a material that contains asbestos in it.
The difference between the two is that an asbestos gasket uses asbestos as a reinforcing fiber while a non-asbestos gasket does not.
Buildings were often built with materials that contained asbestos. Asbestos abatement is the removal of the asbestos, or other treatment such as encapsulation, that will prevent asbestos fibers from being released into the air.
For asbestos inspection, visit the Asbestos Inspection Services website. For asbestos removal, Asbestos Removal, Inc. or Alpha Environ are better choices.
There is no such thing as an asbestos leak, unless you have a container of asbestos and the container is leaking.
Asbestos is generally manufactured by processing mined asbestos fibers.
