Quick Summary

Force-and-spark fireworks utilize a pyrotechnic composition that includes potassium nitrate, sulfur, and finely ground charcoal. Additional ingredients are incorporated to produce various types of sparks, creating visual effects. These fireworks are one of the two main classes of fireworks, the other being flame compositions. The origins of fireworks can be traced back to ancient China, evolving from military rockets and missiles. Over time, particularly in the 19th century, the addition of elements like magnesium and aluminum significantly enhanced the brilliance of pyrotechnic displays.1
