It is surely the same scene each New Year's Eve. Towards 10.00 p.m. at the latest, above all, the big and small men become nervous. Anticipation knows no bounds: around midnight, at the turn of the year, the big fireworks are lit. Rockets, firecrackers and many other pyrotechnic articles guarantee noisy and colourful spectacles in the night sky.
An elementary component of the fireworks is pyrotechnics. It indicates an explosive combustion that cause movement, light, bang, smoke, fog, pressure or irritant effects. The colour of the fireworks depends on the substances contained. Simply put, normally it is about metals, salts and minerals that burn in different colours. Therefore, barium nitrate is used for a green colour effect, sodium oxalate for a yellow and copper oxide for a blue effect.
The most fireworks item are normally sold every year between 27 and 31 December. Other pleasant occasions for magnificent fireworks are birthdays, weddings or anniversaries. However, fireworks are also used in theatre plays and movies. The type of pyrotechnics classifies the fireworks into ground and aerial fireworks. The aerial fireworks include all fireworks items that soar up. Rockets, for example. Ground fireworks include fireworks items that are securely attached to the ground as for example fountains, volcanoes, suns, and waterfalls as well as fire pictures and comets. Bengal fire pictures are a special type. They mostly show writings and pictures. Fireworks items that eject their effects upwards into the air but that do not lift off, occupy an intermediate position between the ground and aerial fireworks.
The first fireworks were probably lit at the end of the first millennium in China. Already back then, light and bang effects were used. In the late 14th century, the use of gunpowder gave birth to an independent art of fireworks which then spread all over Europe. In Japan fireworks were used above all on religious occasions. The Japanese word was HANA-BI, which can be translated into "Flowers of fire". In early modern Europe, the fireworks primarily served for courtly ceremonies and were further developed as an independent kind of event in the baroque period.
The possible injuries resulting from the improper use of fireworks range from burns to hearing impairment up to general injuries caused by falling objects as for example wooden sticks of rockets. However, with a bit of caution nothing should get in the way of a fantastic New Year's Eve with brilliant fireworks. We wish you a lot of fun!
