A Strange New Use for oottonssed Oil.

From the Scientific american
In suitable metallic vessel of something
more than one gallon in capacity is placed
one gallon of pure cotton seed OIL There
are now melted in q furnace In suitable
crucible or ladle twenty pounds Of pure lead
metal, care being taken that the entire
quantity of the lead is In the molten state,
which will insure a temperature thereof of
not less than 334' of heat centigrade. In
this molten state the lead is then poured
gradually In the one gallon of cottonseed
oil, care being taken that the mixture Is
well stirred during the process of pouring,
in order that, as far as possible,
each molecule of the molten lead will
be exposed to the action of the cottonseed
oil. In this process OF pouring the molten
lead, as soon as the hot and molten metal
strikes the surface OF tho oil It follows the
law common to all molten metal when
thrown into liquid and separates into very
minute globules, the bright and pure sur
faces of which are brought in immediate
contact with the cottonseed oil, and by the
heat therefrom impart such affinity to the
cottonseed oil in immediate contact there
with that certain part of the lead will be
absorbed by the cottonseed oil, which, when
removed from the influence of the. heated
gobule of lead, viii immediately cool
sufficient to retain therein the lead
thus absorbed. When the entire twenty
pounds of molten lead have been thus
poured In the gallon of cottonseed Oil it is
allowed to remain some little time to cool
off, after which the oil is drawn off and
there will be found remaining in the bottom
of the vessel In various forms about seven
teen pounds of the pure lead, thus showing
that in this one process of pouring about
three pounds OF lead have been alb
sorbed by the one gallon of cot
ton seed oil. The remaining seventeen
pounds of lead is now removed from
the vessel, and the gallon OF cotton seed Oil,
that has now about three pounds of lead
therein, is returned to the vessel The re-
naming seventeen pounds Of pure lead is
again heated and brought to the molten
state, in which condition it Is again poured
in the cotton seed oil contained Ia the
vessel, the same care being observed in
stirring the mixture during the process of
pouring as in the first pouring of the
metal. <r-t-5..g.- 49,.
After this second process of pouring the
molten lead in the cottohseed oil the mixt~
ure is allowed to cool sufficiently when the
Oil is again drawn from the vessel, and
there will now be found remaining about
fifteen pounds of pure lead, thus showing
that in this second process of pouring the
molten metal two pounds Of lead additional
have been absorbed by the cottonseed oil,
which will now contain about five pounds
of lead combined Herewith. This process
OF remelting the remaining lead and again
pouring and mixing it with the same cot
tonseed oil is continued with advantage up
to the fifth time of pouring the molten
metal, after which the cottonseed oil will
be found to have absorbed about ten
pounds of the lead, after a which there
seems to be no further affinity
Of the oil for the metal. After the cotton
seed oil has been brought TO this stage it is
allowed to thoroughly cool, whom its con-
sistency will be about that Of ordinary
paint. The compound is now in condition
to be applied to those surfaces that it Is de-
sired to protect against corrosive or dete-
riorating influences, and may be applied
with sponge or brush, as in the applica-
ton Of ordinary paint. In applying the
compound It's adhesiveness will cause it to
adhere tightly to the surface coated there
with. IL is preferred to apply one coat. and
then allow it to remain about forty-eiRht
hours, during which time it will have be-
come sufficiently hard to resist ordinary
abrasion, and after which a second coat
may be applied with advantage.
Philip Helbig and Hermann Bertling of
Baltimore, Md, are the authors Of this
new article and process. They say: IL has
been found In practice that no other Of the
known oils, other than cotton seed oil, pos
sesses the quality Of absorbing the lead
when treated as herein described, and that
the cotton seed oil possesses the quality of
absorbing certain proportions of other met
ais when poured In the molten state In the
manner herein described.
As stated, the compound may be en-
ployed to protect metallic surfaces of any
kind, and is claimed TO be particularly use
full for coating the bottoms Of iron or steel
ships to protect the surfaces thereof from
rust and the adherence thereto of barnacIes
and other marine life. 1t is likewise of
equal benefit for the protection of wooden
surfaces that are to be buried in the earth
or exposed to the action of water, such as
fence posts, piles, etc.
