A small but major part of
any explosive is how to ignite it. Some materials, like gunpowder, will ignite quickly when in
contact with flame. But some explosives will not light by just a flame and hence they require some
thing with some more power, maybe even another explosive. What follows is a list of your basic
igniters.
BLACK MATCH
Black match is made with fine, soft cotton
twine and meal powder. It is easily made by twisting 3 or 4 strands of the twine together and
covering the resulting cord with a paste made by mixing the meal powder with water. The excess paste
should be wiped off and the cord should be allowed to dry while stretched across a frame. A slower
match can be made by twisting the twine and using a homemade black powder as the paste. This powder
is made by mixing 6 parts Potassium nitrate, 1 part sulfur, and 1 part soft wood charcoal. This
match and slight derivations are used on nearly ever firework available. Its cheap, reliable if made
right, and easy.
QUICK MATCH
Quick match is black match inserted
into a paper tube which does not need to fit tightly. When light, the black match burns through the
tube at a extremely quick rate.
MINER’S FUSE
Miner’s Fuse is also
called Safety Fuse or Bickford Fuse. It consists of a central thread surrounded by a core of black
powder enclosed within a tube of woven threads, which is then surrounded by waterproof materials,
etc. It commonly burns at the rate of 1 foot a minute. When the fire reaches the end, a jet of flame
about 1 inch long shoots out for the purpose of igniting black
powder or lighting a blasting
cap.
DETONATING FUSE
Detonating Fuse, or Cordeau, is a narrow tube
filled with high explosive. When the explosion is initiated at one end by a detonator, the explosion
travels along the tube with a high velocity which causes other high explosives in its path to
explode. In America, cordeau is made from lead tubes filled with
TNT, from aluminum or tin
tubes filled with Picric Acid, and from tubes of woven fabric filled with Nitrocellulose or PETN (
yes, thats Pentaerythrite Tetranitrate ).
BLASTING CAPS
Instead of
making a whole seperate file out of blasting caps, my first intention, I will just put the stuff
here.
Blasting caps were invented in 1867 by Alfred Nobel, who also first made
Nitroglycerin, invented dynamite and blasting gelatin, and provided funding to start the Nobel
prizes. What a cool dude. There exist 3 different kinds of blasting caps, varying from ant z¤
