Chrysotile asbestos fibers
The uses of asbestos depend upon its fibrous, flexible structure, which allows it to be woven into cloth, felt, etc., and upon its incombustibility and slow conductivity of heat. Asbestos products, therefore, are used for fireproofing and as an insulating material against heat and electricity.
The fibrous variety, chrysotile, has been found in the Province of Quebec, Canada, just north of the Vermont line; from Vermont; New York; New Jersey; Grand Canyon, Arizona, California, etc. Chrysotile was formerly mined in California, Vermont and Wyoming. The production was once large but is now zero. The chrysotile mined in the US comes from masses of serpentine that are cut by many small veins of chrysotile. The whole rock was crushed and the fiber separated out by washing, pneumatic blowing or by some other mechanical method.
