The following is an account by a traveller in the early nineteenth century of a Chinese display: “The fireworks, in some particulars,” says he, “exceeded anything of the kind I had ever seen. In grandeur, magnificence, and variety they were, I own, inferior to the Chinese fireworks we had seen at Batavia, but infinitely superior in point of novelty, neatness and ingenuity of contrivance. One piece of machinery I greatly admired: a green chest, five feet square, was hoisted up by a pulley fifty or sixty feet from the ground, the bottom of which was so contrived as then suddenly to fall out, and make way for twenty or thirty strings of lanterns, enclosed in a box, to descend from it, unfolding themselves from one another by degrees, so as at last to form a collection of full five hundred, each having a light of a beautifully coloured flame burning brightly within it. This devolution and development of lanterns was several times repeated, and at every time exhibiting a difference of colour and figure. On each side was a correspondence of smaller boxes, which opened in like manner as the other, and let down an immense network of fire, with divisions and compartments of various forms and dimensions, round and square, hexagons, octagons, etc., which shone like the brightest burnished copper, and flashed like prismatic lightnings, with every impulse of the wind. The whole concluded with a volcano, or general explosion and discharge of suns and stars, squibs, crackers, rockets and grenades, which involved the gardens for an hour in a cloud of intolerable smoke. The diversity of colour, with which the Chinese have the secret of clothing their fire, seems one of the chief merits of their pyrotechny.”
It will be seen that lanterns play an important part in the exhibition, and that when the fireworks proper are reached, the result is an “intolerable smoke.”
Indian pyrotechnists are more advanced than their Chinese neighbours. Firework displays carried out by them are nowadays more or less crude attempts to reproduce European work.
The writer has seen a set piece evidently intended to follow a fire picture seen in a European display carried out by small wicks burning in oil instead of the “lances,” as the small fireworks used to outline the pictures are called in this country.
In India as in China fireworks play a frequent part in religious and civil ceremonies. In the former country, at certain festivals, a primitive device for producing a series of reports is used. These are called “adirvedis,” and consist of a series of short iron tubes fitted to a wooden plank, charged with gunpowder and tamped with clay.
At weddings, crackers are largely used under a variety of names, such as Vengagvedi, Gola, Pataka or Koroo. To-day these are simple crackers filled with country-made gunpowder or the imported Chinese crackers. Formerly almost the only composition used was chlorate of potash and one of the sulphides of arsenic. A favourite form consisted of a small quantity of the two ingredients put together unmixed into a piece of rag with some small stones or grit and tied. The resulting fireworks were similar to the “throw-down” crackers sold in this country.
Owing to the very large number of accidents caused by the casual methods, both in manufacture and use, with this highly sensitive composition, H.M. Chief Inspector of Explosives for India endeavoured, in 1902, to secure its prohibition, as was done in this country in 1895, but it was not until 1910, when it had been established that this composition was being used by anarchists, that it was finally prohibited.
The most successful effect produced by Hindoo pyrotechnists is the “Tubri.” The composition is here known as Chinese fire, a mixture of charcoal, saltpetre, sulphur and iron dust, charged into either bamboo tubes or earthen pots.
