How To Make Fireworks Strobe Pots
These strobe pot formulas were lifted from the PML and used with the author's permissions. Some of the ingredients may not be available to everyone, but it’s a worthwhile project anyway.
All parts listed are by weight and do not necessarily add up to 100.
OR
The blend of sulfates gives a nice clean white with no greenish cast. (For a nice star substitute 10% of the 60 mesh Mg/Al with -200 mesh. Adding a tiny bit of medium mesh titanium makes a fun star.)
For strobe pots, dampen lightly with nitrocellulose solution and tap or press into a thin wall tube with a wood or aluminum rod. Prime as is normal for ammonium perchlorate mixes.
