14 Great Cut Star Fireworks Formulas




A Collection of Star Formulations

by K.L and B.J. Kosanke

At one time, we were engaged in the commercial manufacture of stars. During that time we assembled (developed, borrowed or modified) a series of star formulations. It was felt that the formulations were reasonably safe and cost effective, while at the same time, performed well (relatively easy ignition and fairly good color or comet effects). Over the years, when asked for advise concerning useful star formulations, we frequently supplied copies of "these" formulations. In the thought that there are others that might wish to have access to them, this short article has been assembled.

Below are the star formulations, given in parts by weight. Unless otherwise noted, water was the solvent used to activate the binder. Normally round stars were manufactured in a star rolling machine. However, the formulations should work equally well to make cut or pressed stars. Where needed, notes have been included for clarity.

(A) Do not prime with meal prime, use only red strobe prime.
(B) Adjust strobe rate by using greater or lesser amounts of Mg/Al (200 mesh).
(C) Priming consisted of a very heavy application of meal prime (30-50% of total star weight).
