HIGH EXPLOSIVES.


HIGH EXPLOSIVES.
United States Said to Have the Most
Powerful Now In Use.
Probably the most powerful high
explosive compound in use is that
which has been adopted by the United
States Government as bursting
charge for shells, known, from the
name of its inventor, as "Maximite."
This explosive Is almost so per; cent
more powerful than ordinary dyna.

than pure nitroglycerine. Notwith.
standing its high explosive property,
however, it is practically insensible
to shock, and will not explode from

red with white-hot iron.
Heated in an open vessel 1t will
evaporate like water, and shells are
filled with 1t by the simple process
of melting and pouring. Like 'Lyd-
dite," "Melinite." 'Shimosedte- and
other high explosives in use by for.

AS originally made, gunpowder was
a loose mixture OF puiyerized sulphur,
CHARCOAL and saitpeter. Then 1t was
actually powder, not graduated, as
is the present form of ordinary smoky
black powder. The idea of granuka.
tion probably arose from the admix-
ture of bituminous matter with the
powder to retard the combustion.
The first method!cal granulation OF
guapowder recorded was in France, In
1925. IN 1854 General 7. j. Rodman
invented prismatic powder. designing
presses for molding the grains sepa-
rately and giving them uniform
shape He also made musti-perforated
powder grains to insure progressive
combustion.-W. R. Stewart. IN Tech
