    Ball Milling Theory Introduction: Figure 1: Ball milling terminology. I was first given the formula for gunpowder by my Uncle at age 14, after he had observed my apparent obsession with class C fireworks. Being a scientist who had experimented with the ancient recipe himself during his youth, he thought I should try making my own fireworks.
