They
couldn’t let black powder get all lonesome by being the
only worthwile powder useful in
explosives, so somebody invented
a few more. Some of these are better than black powder,
some
worse, some more expensive, some more convenient. But they are
all powders.
BLASTING POWDER
Since normal black powder burns rather quickly when mixed
well, a slower and cheaper powder is needed for blasting. A
powder of this type can be
obtained by reducing the amount of
Potassium Nitrate. The French government has manufactured
and
sold the following kinds of blasting powder.

In
the United States, most blasting powder is made from
Sodium nitrate. Some samples taken show
the following ratios.

Pellet powders, made from Sodium Nitrate,
are becoming
popular. They are cylindrical pellets, 2 inches long, wrapped in
paraffined
paper cartridges, and are from 1 and 1/4 to 2 inches
in diameter. The pellets resemble
cartridges of dynamite. From 2
to 4 pellets whice are perforated in the direction of their
axis
are wrapped in the cartridges and a 3/8 hole is bored for
insertion of fuse for
firing. The pellets are also sold in most
hardware stores for use in welding torches under
names like Solid
OX pellets and generally cost about $ 8.00 for a can of 7 or 8
sticks.
You can buy these pellets and grind them up for a good
source of Sodium Nitrate powder. It
makes a hell of a black
powder.
II. AMMONPULVER
Propellant
powder made from Ammonium nitrate is about as
powerful as smokeless powder and has long had a
limited use for
military uses, especially in Germany and Austria.
In 1855, a powder was
patented called Amidpulver. Later the
formula was improved, giving the powder a flashless
discharge
whan fired in a gun and only a moderate amount of smoke.
Ammonpulver which
contains no Potassium nitrate explodes with no
flash and little smoke.

Ammonpulver has the advantages of being cheap, powerful,
flashless, and almost smokeless. It
is insensitive to shock and
friction, and is more difficult to ignite than black powder. In
III POUDER BRUGERE
Pouder Brugere is made by grinding together the following
composition :
Ammonium nitrate 54 parts
Potassium nitrate 46 parts
The powder is pressed and
granulated as in the making of black
powder. It is more powerful than black powder and gives
less
smoke.
FRENCH AMMONAL
French Ammonal is an easily
improvised low explosive mixture
of 86% Ammonium nitrate, 6% Stearic acid, and 8% Aluminum
powder.
It is generly less effective than and equal weight of TNT.
Initiation by a
Engineer’s special blasting cap is recommended.
