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
|
|||
|
|
use it requires a strong igniter charge.

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.
