At some point fairly early in every pyro career we realize we need to be able to make good black powder (BP) from scratch. BP is used in aerial fireworks shells as lift and burst powder. It is also used, in one way or another, in almost every other pyrotechnic device and component--mines, stars, black match, and the list goes on.

Obviously, in this introduction to rockets, we won't be discussing military rockets, which have a long and rich history. Neither will we be discussing rockets designed for space exploration, which we'll leave to NASA.

“Garnitures.” Kind of an old-fashioned word, not heard very often in conversation. But, as used to describe the class of fireworks components we are about to look at, I’ll be darned if I can find a better word. From “Traditional Cylinder Shell Construction, Part I” by A. Fulcanelli, found in Pyrotechnica IX: “Garnitures. The general [...]

I was in pig heaven when I got my new star rolling machine from John Smith. But the very first batch of stars came out looking like they had contracted a king-hell case of warts. Looked like raspberries – all bumpy all around. Actually, there was an easy fix, but I didn’t have a clue [...]
