A New Manufacturing Industry in
Stanhope.

The manufacture of what is known as
Mineral Woolis quite extensively carried
on in Stanhope, and bids fair to prove a
source Of considerable revenue to the pro-
jectors as well as beneficial to the town.
The following interesting facts concern
ing the new industry are furnished theLroa,
Era by it's Port Norris correspondent,
who it seems has "bin thar;
"The factory fur the manufacture of
mineral wool at the Stanhope furnaces, is
now finished and in complete running or
der The process is as simple as dish
water, after you see how it is done, and
the wonder is that nobody thought of it
before. 1t has been made at Greenwood
furnace, Orange Co., N. Y, for the last
six years, by r. d. A. Parrott. 1t is
made from the Stag, or cinder, from the
furnace. While this Stag is in fluid
state it is allowed to fall in small yes
sci, upon a jet of steam or compressed air
the effect of which is to disintegrate the
molten Stag, which cools as it is carried
forward in the form Of wool, resembling
Sleeps wool or cotton. The ingtantan
eous separation causes q thread or fibre
to be pulled out which varies in length
thickness and color, according to the flu
| idity and composition of the Stag. Wher
gathered up the fibres appear to lie in al
possible directions with relation to eacl
other, in consequence of which there is ne
parallelism or common direction of thu
| threads, so that the air spaces are angular
| in shape and microscopic in size. TIL,
wool is collected in large chamber
where it settles in q bulky state, having
fleecy appearance. About so per cent, O
the product has to be riddled, formin,
the ordinary grade, while the balance il
separated by currents Of air, and form tn,
extra grade. While the molten Stag il
falling ON the Jet of steanl-all you cal
see is a shower of sparks, but when thes
are blown into the large chamber ant
cool off you have a substance lookin:
| like the finest and whitest WOOL
1t Is used for the following purposes
To prevent condensation of steam in boil
ers, cylinders and pipes, to prevent freez
ing of water mains, service pipes, fee,
pipes to cisterns and tanks, to protect no
| blast pipes about furnaces and mills; t.
protect ice i'll coolers, refrigeratOrs an,
ice houses to insula.e cold storage hous
es, brewery cellars and wine rooms; 70
lining floors of passenger cars, to deade
the sound, keep the lower part of the ca
warm in Winter, and to adjust the centr
Of gravity Of the car as filling for roof
side walls, floors and partitions, to pre-
vent the passage of heat either in or out
to deaden sound between rooms to pre-
vent the inroads of rats, mice or insect:
and as prevention against the spread {
fire. The ordinary grade of it weigh
about 90 pounds to the cubic foot, or 7
pounds to the bag, and costs cent pc
4 pound. The extra weighs 10 pounds t
the cubic foot, sells for 3cents per poun(
and you can get IRON 80 to 30 pounds {
it in a bag-three bushel bags being use
in each case. The exclamation which
could not suppress, as stood and locke
at the transformation of this materia
which has been wasted for years, int
something useful was, Great is Science
some day there will be no such thing a
waste material Some Yankee will Il
cate at the mouth ofevery known volcs
no yet and convert the burning lava int
mineral wool. 1t is said the Stag froI
Stanhope furnaces makes the best minert
| wool and the most of it of any that ha
been tried
