The pyrotechnic art has been remarkably slow


In Europe, pyrotechnics for military purposes saw an early peak of achievement in the form of Greek fire. Old manuscripts suggest several ways of attempting to combat the fireworks, especially the application of wine, vinegar, sand and even urine.

More peaceful uses of these crude articles appeared in the form of firecrackers-the first fireworks? One mixture corresponded quite closely to modern gunpowder in that it contained saltpeter, sulfur and willow charcoal. The firecracker was said to consist of a loosely-filled small hole to accept a match or fuse.
Firework manufacture has a long history, but the development of the pyrotechnic art has been remarkably slow.

The Chinese may have made fireworks of sorts over a thousand years ago; displays have been fired popularity, now worldwide, seems undiminished. Nevertheless, basically, firework displays have changed little over the centuries, with rockets, shells and roman candles, in various forms, remaining the main display components.
