@X083@X05.@X0821 @X03 BLACK POWDER
@X08First made by the Chinese for use in fireworks@X05,@X08 black powder was first
used in weapons and explosives in the 12th century@X05.@X08 It is very simple to make@X05,@X08
but it is not very powerful or safe@X05.@X08 Only about 50@X05%@X08 of black powder is
converted to hot gasses when it is burned@X05;@X08 the other half is mostly very fine
burned particles@X05.@X08 Black powder has one major problem@X05:@X08 it can be ignited by
static electricity@X05.@X08 This is very bad@X05,@X08 and it means that the material must be
made with wooden or clay tools@X05.@X08 Anyway@X05,@X08 a misguided individual could
manufacture black powder at home with the following procedure@X05:@X08
MATERIALS EQUIPMENT
@X05_________ _________
@X08potassium clay grinding bowl
nitrate @X05(@X0875 g@X05)@X08 and clay grinder
or or
sodium wooden salad bowl
nitrate @X05(@X0875 g@X05)@X08 and wooden spoon
sulfur @X05(@X0810 g@X05)@X08 plastic bags @X05(@X083@X05)@X08
charcoal @X05(@X0815 g@X05)@X08 300@X05-@X08500 ml beaker @X05(@X081@X05)@X08
distilled water coffee pot or heat source
1@X05)@X08 Place a small amount of the potassium or sodium nitrate in the grinding bowl
and grind it to a very fine powder@X05.@X08 Do this to all of the potassium or
sodium nitrate@X05,@X08 and store the ground powder in one of the plastic bags@X05.@X08
2@X05)@X08 Do the same thing to the sulfur and charcoal@X05,@X08 storing each chemical in a
separate plastic bag@X05.@X08
3@X05)@X08 Place all of the finely ground potassium or sodium nitrate in the beaker@X05,@X08 and
add just enough boiling water to the chemical to get it all wet@X05.@X08
4@X05)@X08 Add the contents of the other plastic bags to the wet potassium or sodium
nitrate@X05,@X08 and mix them well for several minutes@X05.@X08 Do this until there is no
more visible sulfur or charcoal@X05,@X08 or until the mixture is universally black@X05.@X08
5@X05)@X08 On a warm sunny day@X05,@X08 put the beaker outside in the direct sunlight@X05.@X08 Sunlight
is really the best way to dry black powder@X05,@X08 since it is never too hot@X05,@X08 but it
is hot enough to evaporate the water@X05.@X08
6@X05)@X08 Scrape the black powder out of the beaker@X05,@X08 and store it in a safe container@X05.@X08
Plastic is really the safest container@X05,@X08 followed by paper@X05.@X08 Never store black
powder in a plastic bag@X05,@X08 since plastic bags are prone to generate static
electricity@X05.@X08
