The
sulfur can be replaced by antimony trisulfide and the sound of a salute
made with this composition will change very little.
potassium perchlorate.............................50
Aluminum..........................................23
sulfur............................................27
Flash #2
potassium
perchlorate.............................70
Aluminum (dark pyro)..............................30
Flash #3
Larger
percentage of aluminum results in a stronger flash. This composition
is slightly less sensitive than the usual perchlorate mixtures which
also contain sulfur.
Potassium perchlorate.............................65...70%
Aluminum powder...................................rest (up to 100%)
Flash #4
Potassium
perchlorate.............................3
Aluminum, 400 mesh................................3
Sulfur............................................1
Flash #5
This
is a relatively safe flash composition. Burns with a brilliant white
light in an open tube, or when unconfined. When well confined, it
produces a loud, low pitched report and a short but intense flash.
Potassium nitrate.................................50
Sulfur............................................30
Aluminum..........................................20
Flash #6
Can
be ignited by a fairly low temperature flame, and produces a greenish
flash when magnesium is used. Burns very fast, and produces a loud
report even in an open container.
Magnesium or Aluminum.............................1
Barium sulfate....................................1
Flash #7
Relatively
insensitive.
Barium nitrate....................................4
Alumium (fine mesh)...............................2
sulfur............................................1
Flash #8
Dampen
the mix lightly with water and mix thoroughly such that the material
is crumbly but then packs tightly into a ball. If it is at all greasy
feeling or mushy, there is way too much water. Save some dry mix on
the side just in case it becomes too wet during the dampening. Granulate
the damp comp by rubbing the packed ball over a 20 mesh screen. Do
not use any screens larger than 20 mesh. If the screen plugs, the
comp is too damp. Add more dry comp and thoughly mix in. After drying
the granulated powder, it can be used in flash bags. About 3 to 5
grams works well in a 3 inch shell. Experimentation is needed to adjust
the amount of burst for good results with different stars and shell
construction. This powder can also be used ungranulated, in a central
flash bag, in larger shells.
Potassium nitrate.................................3

Barium nitrate....................................1
Antimony sulfide (CN).............................1
Sulfur............................................1
Dextrin...........................................1/2
Flash #9
The
use of permanganate in pyrotechnic compositions is not recommended,
since it is unstable and will decompose over time. Also, like all
flash mixtures, this mixture is quite sensitive and powerfull. Great
care should be taken when handling this mixture.
Potassium permanganate............................12

Flash #12
This
composition produces slightly less noise than "Flash #11",
but is safer to handle than similar compositions containing sulfur.
