Natural Textile Fibre

3. Asbestos is a set of six naturally
occurring silicate minerals, which
all have in common their
eponymous asbestiform habit:
long (roughly 1:20 aspect ratio),
thin fibrous crystals, with each
visible fiber composed of millions
of microscopic "fibrils" that can
be released by abrasion and other
processes

4. Industrial scale asbestos mining began
in 1878 in Thetford township, Quebec.
By 1895, mining was increasingly
mechanized.
