Flash Powders
Flash Powders are high energy explosive
mixtures and require the utmost caution in their manufacture.
Of the Flash
Powder mixtures listed below, the ONLY one that should be used in Salutes
(exploding fireworks) is the Industry Standard 70/30 Flash Powder.
Older
Flash Powder mixtures containing Potassium CHLORATE or Sulfur are very sensitive
to friction and static electricity and have exploded without warning.
The
70/30 formula uses just Potassium PERCHLORATE and Aluminum, which is a much more
stable and reliable chemical mixture.
Grind the Potassium Perchlorate ALONE
in a mortar & pestle until it is a very fine powder. Pour it into a zip-loc
plastic baggie and then add the Aluminum Powder.
Don't ever grind the two together as the mixture may
explode.
Close the baggie and shake it back &
forth until the Flash Powder composition is well mixed.
Never grind, pound, or subject any Flash Powders to friction as
they may explode.
