Asbestos, Its production and use: With some account of the asbestos mines of Canada

Asbestos; Asbestos mines and mining -- Québec (Province)
Improved stove pipings are now being manufactured in the States which in
appearance exactly resemble cast-iron. These have the additional
valuable properties of extreme lightness, combined with great strength
and a capability of ornamentation unobtainable with the usual cast-iron
pipes mostly in use; paint in the case of the asbestos pipes not scaling
off under heat as it will do in the case of ordinary iron pipes. The
manufacturers of these pipes claim for them that they combine the
strength of steel with the lightness of paper. Tubes also are made for
electrical engineers which provide them with a non-conducting covering
for their wires both fire and waterproof, so as to preserve the perfect
insulation of the wire.
Asbestos rope is used for fire escapes and similar purposes, as well as
for the transmission of power over places exposed to heat. In dyeing and
printing cloth it is frequently necessary to hang the fabric in loops
from parallel rods for exposure to steam, air or ammonia. In order that
it should hold upon the rods, without straining or slipping, rope or
strips of cloth are usually wound around the poles, but this does not
remove, although it mitigates, the difficulty, because the heat and
corrosive action of the vapours will rot any covering; the first notice
of the deterioration being generally the appearance of small pieces of
rod covering among the cloth which is in process of finishing. Asbestos
rope and cloth are now largely manufactured and used for this purpose
in the United States with very beneficial results.
In commenting on the recent loss of life occasioned by the panic at the
fire at the Exeter Theatre, a well-known journal, speaking of the
various modes of providing for escape, mentions the case of a man of
fashion, a millionaire, who died not long ago, and says that he would
never go to bed in a strange house without having an apparatus of
knotted rope affixed to a ring in the wall, by which he might lower
himself to the ground on an emergency. But, asks the journalist, what if
the rope itself took fire? The answer naturally is, let it be an
asbestos rope, then it will neither burn nor rot.
The use of the fibre in the manufacture of gas stoves is too well known
to need any remark.
As a lubricant it is unrivalled.
