*****************HOW TO MAKE GUN-COTTON**********************
|
|
|
|
|
|
|
|
If only a small quantity is required---Mix 4 1/4 oz of pure dry
|
|
Potassium Nitrate with 30 fl.dr of Sulphuric acid specific gravity
|
|
1.845 ish and stir into this mixture 120 grms of pure cotton.
|
|
(The adding of Potassium Nitrate straight to the Sulphuric acid
|
|
saves you having to buy the Nitric acid , which can be a bit of a
|
|
pain sometimes).
|
|
As soon as saturation is complete,in about a minute,throw the cotton
|
|
into a large container of water under the tap and leave the tap on,
|
|
so that all the acid is washed out...THAT MEANS ALL..Test the water
|
|
with Litmus paper to be sure.If the cotton is left slightly acidic
|
|
it will explode at some later date;all by its self wouldn,t that be
|
|
fun.!!!!
|
|
Then squeeze it out into a towel till it feels quite dry and then
|
|
finally dry it at about 180 F.
|
|
Gun-Cotton differs widely from Gun-Powder in its properties requiring
|
|
a much lower temperature for its ignition about 136 F G-P about 250 F
|
|
Gun-Cotton burns so fast in the open that you could put some on your
|
|
hand and light it , you wouldn,t feel a thing !!
|
|
It needs to be confined in a strong case if your fuse is a normal
|
|
Black-Powder one but if you use a detonator ie/a Fulminate it will
|
|
explode on its own.
|
|
|
|
Rapid as this combustion is,however,it occupies an appeciable time,
|
|
as may be seen by igniting a train of loose gun-cotton,which takes
|
|
several seconds to burn a few feet,giving at the same time a large
|
|
flame. If gun-cotton be confined at the moment of ignition this flame
|
|
is forced back into the mass.and by rapidly heating it brings it to
|
|
the point at which combustion passes into explosion.Prior to 1868
|
|
it was always confined in strong cases,but in that year someone
|
|
discovered that when a detonating fuse was exploded in contact with
|
|
compressed gun-cotton,the unconfined mass at once exploded with
|
|
ENORMOUS violence,and this discovery opened up an entirly new ball-
|
|
game.
|
|
The products of the explosion are :- Carbon Dioxide
|
|
Carbon Monoxide
|
|
Hydrogen
|
|
Nitrogen
|
|
Methane
|
|
It can be detonated buy hitting with a hammer on an anvil but only
|
|
the portion under the hammer will explode with a loud report.
|
|
|
|
To recap,do make sure that all the acid is washed out..
|
|
|
|
and lets be careful out there...........IVAN
