Pyro-pal: you know the formula of this effect; like a cascade ?
Here’s the firefly formula, but it only preformed like a cascade the first time I tested it.
Subsequent tests performed miserably due my veering from the original parameters.
i.e cutting the stars larger than 10mm and not using a thin enough wheat paste binder.
Still have some more tests before it’s dialed in, but that’s typical of this type of effect.
Firefly Stars:
Saltpeter-----------44
Barium Nitrate ----5
Airfloat C-----------29
80 mesh C --------11
Sulfur-----------------6
Al Flake -------------5
Paste Binder: use 1oz. dry wheat paste to 1-1/2 pints water heated in a double boiler then cooled. Me thinks an even thinner paste binder is needed here. Add 275 cc of paste to 500 grams of the star comp.
Cut to 10mm square. Save the crumbs and recover the aluminum.
Aluminum is Transmet K101& K102 flake, about 20-30 mesh (2.5 parts of each to equal 5 parts total.)
