At the siege of Pian-King Lo-Yang (1232), as mentioned in the Chinese Annals, iron pots were thrown containing a burning substance which could spread fire over half an acre, and described by the historians as the “thunder which shakes heaven.”
The Mongolians attacking Bagdad in the year 1258 made use of similar vessels, also fire arrows. Marco Polo, describing sieges of towns in China 1268 to 1273, mentions the throwing of fire.
In most of the early records although noise is remarked upon, it is apparently while the projectile is in the air or upon impact; this disposes of the impression which many writers have formed that firearms are referred to, there being no reference to an initial explosion.
Sir George Stanton, writing in 1798 of his embassy to the Emperor of China, says that “nitre (saltpetre) is the daily produce of China and India, and there accordingly the knowledge of gunpowder seems coeval with that of the most distant historic events. Among the Chinese it has been applied at all times to useful purposes ... and to amusement in making a vast variety of fireworks—but its force had not been directed through strong metallic tubes, as it was by Europeans soon after they had discovered that composition.”
Although the place of origin of the art, pyrotechny has not developed in the East as rapidly as in Europe, except in Japan.
Japanese pyrotechnists, with that wonderful capacity for careful and exact manual work which is so characteristic of the race, have developed aerial fireworks, that is to say, the shell, to a remarkable degree of perfection. The compositions used are not to be compared with European manufactures in point of colour or brilliance, but the effects obtained are extraordinary. The stars, upon the bursting of the shell, are thrown out in symmetrical patterns and designs, several examples of which are given in the accompanying Japanese colour prints.
Daylight fireworks also originated in Japan. Instead of pyrotechnic effects, the shell contains a grotesque balloon in the form of an animal, human figure, or other form, which, being open and weighted at the lower end, becomes inflated as it falls and remains in the air for a considerable period. Other daylight effects are coloured clouds formed by coloured powder, distributed by the bursting of the shell, showers of streamers, confetti, and toys.
Chinese firework displays have often been enthusiastically described by travellers in China. Whether it is that the glamour of the East distorts the perceptions, or that these travellers have not seen a European firework display, there is no doubt that such descriptions are, to say the least, over coloured.
Chinese fire (a composition of saltpetre, iron filings, sulphur and charcoal), a few simple colour compositions, and a large number of Chinese crackers of varying sizes constitute a Chinese display; the rest of the exhibition being eked out with lanterns, pictures, etc., which certainly do not come under the heading of pyrotechnics.
The writer once had an opportunity of witnessing a Chinese display of some importance, lasting several hours, which produced the effect on the mind of watching some performance or game of the rules of which one was in entire ignorance. Pyrotechnically, only the crudest effects were produced, the remainder of the display, consisting of such items as a man slowly climbing a ladder carrying a lantern, was to the uninitiated mystifying.
