Asbestos History: First Use in 2500 B.C.
The earliest known use of asbestos was in about 2500 B.C. in what is now Finland. Fibers were mixed with clay to form stronger ceramic utensils and pots. The first written reference appeared in Greece around 300 B.C. when Theophrastus, one of Aristotle's students, wrote a book entitled
On Stones. He mentions an unnamed mineral substance, which looks like rotten wood, yet isn’t consumed when doused with oil and ignited.
Greeks used it to make lamp wicks and other fireproof items. When the Roman naturalist and statesman Pliny the Elder wrote
Natural History around 60 A.D., he described this fire-proof mineral and gave it the name asbestinon (meaning unquenchable), which is the origin of the English word asbestos.
Centuries of Fascination
The mineral’s qualities continued to fascinate the scientific community for centuries, but it wasn't until the 1800s that asbestos found commercial success. The first United States patent for an asbestos product was issued in 1828 for a lining material used in steam engines. In 1868 Henry Ward Johns of the United States patented a fireproof roofing material made of burlap and paper laminated with a mixture of tar and asbestos fibers. It became an
immediate hit, as did other products.
Large-scale mining of asbestos deposits near Quebec, Canada began in 1878 and spurred the development of other commercial uses. By 1900, asbestos was being used to make gaskets, fireproof safes, bearings, electrical wiring insulation, building materials, and even filters to strain fruit juices.
Technology Spurred Even More Uses
Technological developments in the 1900s resulted in more uses for asbestos. For example, many early plastic materials relied on asbestos fibers for reinforcement and heat resistance. Additionally:
• Vinyl-asbestos tile became one of the most commonly used floor coverings and was produced well into the 1960s
• Automobile brake linings and clutch facings also used large amounts of asbestos, as did many building materials
WWII Increases Production
After World War II, asbestos was
used in more and more products. Heart surgeons used asbestos thread to close incisions, Christmas trees were decorated with asbestos artificial snow, and even a brand of toothpaste was marketed using asbestos fibers as an abrasive.
