History of Pyrotechnics
The birthplace of fireworks is generally recognized as China,
with the first explosive mixture found being black powder, during
the Sung dynasty ( 960-1279 ).
It is said that a cook in ancient china found that a mixture of
sulfur, saltpeter, and charcoal was very flammable and would explode
if enclosed in a small space.
The first application of this technology was for entertainment.
The Chinese are still the leader in the production of fireworks.
Once the recipe for black powder was perfected, they found that
it was easily used as rocket fuel, and they made hand carved wooden
rockets in the shape of a dragon, in the sixth century.
These rockets shot rocket powered arrows from their mouth, and
were used against the Mongol invaders of 1279.
The principle behind these rockets is still used in rocket powered
fireworks today.
Through adventurous
explorers, the knowledge of making fireworks spread west, through
Arabia in the seventh century. The Arabs called the rockets Chinese
arrows.
The Mongols are credited with taking Chinese rockets and gunpowder
to Europe around 1241. The first record of their use in Europe
are around 1258. Until the 19th century, fireworks lacked a major
aesthetically essential characteristic: color. Pyrotechnicians
began to use a combination of potassium chlorate and various metallic
salts to make brilliant colors.
The salts of these metals produce the different colors: strontium
burns red; copper makes blue; barium glows green; and sodium,
yellow. Magnesium, aluminum, and titanium were found to give off
white sparkles or a flash.
Even though
China invented the fireworks, Europe surpassed them in pyrotechnic
development in the 14th century, which coincides with the time
the gun was invented.
Shot and gunpowder for military use was made by skilled tradesmen,
later called firemakers, who also made fireworks for peace or
victory celebrations. During the Renaissance, two European schools
of pyrotechnic thought emerged: one in Italy and the other at
Nuremberg, Germany.
The Italian school of pyrotechnics emphasized elaborate fireworks,
and the German school stressed scientific advancement. Both schools
added significantly to further development of pyrotechnics, and
by the mid-17th century fireworks were used for entertainment
on an unprecedented scale in Europe, being popular even at resorts
and public gardens. In the mid-19th century fireworks became popular
in the United States.
Injuries associated with fireworks, particularly to children,
eventually discouraged their unrestricted use. As a result, in
many states of the U.S. and in parts of Canada the sale of fireworks
is now restricted by law.
