CHAPTER II


PYROTECHNY IN THE EAST

ssss1

Pyrotechny undoubtedly had its genesis in the East, and for that reason we will deal with its development there first. As he has intended to convey, the writer is strongly of opinion that the discovery of pyrotechnic compositions antedated that of gunpowder. In many cases earlier writers have discovered passages which they consider prove the use of firearms and gunpowder; in reality these refer to Greek-fire and similar compositions, which were used as projectiles, being thrown from machines or catapults, and not as propellants. Gunpowder as a mixture of ingredients may have been known from remote times, as undoubtedly were other simple pyrotechnic compositions, but all evidence goes to show that its use as a propellant was not known until well into the Christian Era.

The composition Greek-fire, known in ancient times as “naphtha,” was a mixture of pitch, resin, and sulphur, with the addition in some cases of crude saltpetre. It may be considered that in the absence of the latter ingredient the mixture does not constitute a pyrotechnic composition, but from the description of the use of “naphtha” in early writings, it appears at least likely that it was generally present.
