Firecracker

The Chinese, however, had employed pyrotechnic mixtures long before this date. Ancient manuscripts describe explosive bombs, which were fired from giant catapults, and burst on landing or in the air. Similar missiles were merely dropped on the enemy from fortress walls. Firecrackers were often in early times, just as they are now, to scare away evil spirits from wedding and birth celebrations and from funerals, and they were also much in evidence at various religious festivals. These crackers were often made by packing gunpowder in to bamboo cases or rolled paper tube, so laying the foundations of modem firework manufacture. They exploded when thrown on to the fire, hence the origin of the name “firecracker”.

It is probable that first gunpowder was formed when, quite by chance, charcoal, saltpeter and sulphur were brought together. Traditionally, the Chinese are credited with the discovery at a time well before historical records. Certainly the evidence suggests that gunpowder originated in the east.

Firework manufacture

Considerable opposition has been directed against the sale of fireworks, or even their manufacture, in almost every country where they are made. Certainly in the U.S.A. and the European union, governments have often reacted vigorously, and sometimes with almost hysterical haste, in response to campaigns for greater control. In the united states, different legislation applies in the separate states. Some administration ban the sale of all types of firework, while others allow only “safe and sane” types, which include flares, candles, fountains, wheels, sparklers, etc., but not those with explosive elements.

Firework manufacture is an art, but for the manufacturing companies it is also a business. As such, it faces the multitude of problems which confront all other businesses in the modern, competitive commercial world. Above all, the work must show a profit, and with rising costs of materials and transport, increasing wage bills, higher insurance premiums, the escalating costs, expenses of various overheads, the expensive safety regulations imposed by the authorities.

Fireworks were introduced to the united states by immigrants

In the nineteenth century, many American manufacturers were branches of European companies. The earliest known manufacturer of fireworks for pleasure in the U.S.A. was the Du Pont family near Wilmington,Delaware in 1809. the business thrived until the 1940s and continued to supply powder for the industry until the 1970s.

China is usually considered the birthplace of black powder and firework making. Hundreds of factories supplied material for fireworks display celebrating religious festivals and public events, marriages and funerals.

Recent political changes in china have meant that many manufacturers are now allowed to invest private capital and trade unhindered across the world. Certainly, china leads the world in the volume of production and export. A large number of small companies,especially in Guangdong, Guangxi, Hunan,Jiangxi and Hebe provinces, feed the large exporters and display companies, which operate under such group titles as temple of heaven of Beijing or red lantern,and brand names like sunny, Vulcan and an ping.

A large percentage of the fireworks produced in Japan used to be exported, but this is no longer the case;the bulk of them are used internally. This is because they require so much expensive hand labor that the finished products are very costly.

Firework Display

Firework displays were seldom seen in England before the end of the sixteenth century. Shakespeare refers to “fireworks” on several occasions in his plays, suggesting that the term was in general usage in England in Tudor times. Other literature of the head often mentions the “green man” whose function was to walk at the head of processions carrying “fire clubs” and scattering “fireworks”(in this case probably meaning sparks)to clear the way.

The origin of this character and his title are a mystery, but we are told that he was usually made up to appear very ugly, and he certainly survived well into the following century.

The earliest record of a firework display in England was in 1572, when a large fireworks show was put on at Warwick castle to mark the visit of queen Elizabeth I .

Early Chinese formula recorded in the 1044 about 60% of saltpeter,sulfur 30%,charcoal 10%,but the preparations including sesame fibred,bamboo fibred,arsenic,lead salt,oil and resin.Assumption is that organic material will need to carbonation. Lead and arsenic compounds may recommend another toxic fumes of a military nature.
While on the gunpowder and weapons in India and Muslim countries,to use some public relations work.for more than the British Ĵ ash project study on the authority of gunpowder,views,and Chinese origin.It may be from the 1225,gunpowder technology from China by the Indian National transmitted to the veil.Later.Gunpowder,the Arabs and then send to Spain.Spread to Europe by the mid-16th century.It was suggested that Roger Bacon discovered gunpowder by the Arab book translation.
In later times,the Arabs called saltpeter"Chinese Snow"and the Persians called the"Chinese salt"
There is no doubt that the original gunpowder burn well and produces a considerable amount of natural gas.

Fireworks Gunpowder History(Ⅱ)

The so-called "black powder a resplendent pearl, in chinese civilization to the three parts even known from the earliest times.
Charcoal was already used at the Bronze Age in China and recognized as fuel for the reduction of metal ores.
Sulfur was recorded in the 6th century BC and in other documents it was regarded as remarkable for its ability to dissolve metals like gold , silver ,copper and iron. It is also featured in medicine.
There is considerable evidence of the existence and knowledge of Saltpeter . Once again, its reactivity with metals its use in medicine in the elixir of life recipe established its importance in these times.
It has always been stated that the origins of black powder are Chinese and much of the evidence has been found in books printed in the west . We are happily in the position now to have more authentic evidence from a document forwarded by professor Fe n g Chang gen of the Beijing institute of the authors of the paper” The Origin and Development of Ancient Gunpowder” were Yang s h u o and Ding Jing(42).

Fireworks Gunpowder History(Ⅰ)

China consider that the properties of gunpowder were discovered during the period 475-221 BC with the rise of interest in alchemy and the urge to perfect the making of both gold and the elixir of life. han dynasty (about the 206年) alchemy increasingly popular, but the exact details of the origin is not clear, this is not the main the alchemists were looking for.

The 1st serious formulations for gunpowder as know it seem to stem from writings about AD808 when sulfur and charcoal have clearly entered the trials though the object was not necessarily to produce explosions so much as to subdue them. It was reported that mixtures of saltpeter, sulfur, raga and honey created fires which burnt hands, faces and houses. The addition of charcoal to hot mixtures of saltpeter and sulfur would certainly have been inflammatory!

The fourth of the search for the elusive also takes active. saltpeter remains the principal constituents, but the experiment may have some water on the way, a mixture of saltpeter or resin and the pig. it is found that, under certain conditions will be a mix of explosives.
