called-are that 1t is absolutely non
inflammable; is fireproof up TO $500 de-
grees F.; is lighter than cork dump
zonolite weighs only 6 pounds to the
cubic foot as against 10 pounds for
cork; is vermin proof: is insoluble in
water Il acids; is unaffected by wealth
er, is equal to mica as a dielectric: is
effective as a sound deadener; is Of great
decorative value; is adaptable TO a vast
humble Of commercial uses; is easily
fabricated, and can compete in price
with other substances now used, all of
whose desirable properties it has as we'll
as others exclusively its own.
Experiments which have been conduct
ed in hundreds of laboratories, as indi-
Gated by letters received by the company
and adoption OF the product in many
lines OF industry, not only substantiate
the claims made for zonolite but are dis
closing new fields of usefulness for it.
That it Will replace cork in refrigeration
and asbestos in insulation against cleo
tricity and heat are among the opinions
expressed by various manufacturer as
to the wide range OF its commercial pos
sibilities.
The principal uses for which the value
Of Zonolite has been demonstrated in
clude heat n cold insulation and fire.
PROBING, house insulation, electric in
sulation, %fireproof building materials,
ulAQ AdAb R4OOAliB u highways. manly
other incidental uses for 1t have also
been discovered.
Although the first carload shipment
of zonolite was made only three years
ago Tin March 1920 and It's commercial
use began really to get under way only
two years ago, such is the momentum it
has gained that the volume Of sales last
year was five times that of 1926 and at
present zonolite is being shipped in car
load lots to l6 customers including sew
eral of the greatest industrial concerns
in America, and less than carload lots
to so more customers, not only through
out the United States and Canada, but in
Japan, Belgium, England and Germany.
Among the Industries now using Zon-
olite in carload lots are manufacturers
of mill board, wall plaster, pipe and boil
err coverings. electric bake ovens, petrol
cum products, safes and cabinets, wall
paper, mineral, lumber and cork prod
ucts, n concerns handling house in
sulation. Six plants in various parts of
the country for the fabrication exclu-
sively of zonolite products are now In
operation II a seventh to cost $3.50, 900
is now under way in Los Angeles for the
manufacture on a large scale Of "zono-
lite mineral lumber
Thu Zonolite company, according to
Mr.. Alley, will confin itself exclusively
to the mining and processing Of the
mineral.
The bulk of its shipments is of the
treated material, ranging in texture from
Jumps to a fine powder of 100 mesh. This
Is turned out by a plant at Libby COM
pleted in January, 1927, which has a
daily capacity of 100 tons
Mining and treatment costs are very
low and will be further reduced with
the construction Of a projected aerial
tram from the mine to the Great North
ern railroad Interstate commodity
freight rates have also been secured to
practically all points in the United
States and the publication Of interstate
rates IN zonolite in Montana Is expected
soon. When these are granted a rapid
development of its use throughout Mon
tana, especially for house insulation, is
anticipated.
The demonstrated superiority of zono-
lite over other products in a great vari-
city Of industrial applications indicates
for 1t a potential market of vast volume
and developments of recent date strong
ly suggest that in the comparatively near
future this unique and exclusively Mon
tana product will be moving in quanti-
ty into world wide channels of industry,
contributing in many ways to the COM
fort and progress OF humanity and add
Ing q new jewel to the diadem Of the
Treasure State"
