It is believed that fireworks were first created and used in China in the 7th century at festivals. It soon spread to other countries and cultures. However, they were not as colourful as they are today. As time went on, they became more popular and are now a specialised profession. A lot of the fireworks used, were rockets on a stick. Gun powder was a main source in creating the effects of fireworks. Various forms were used in warfare. Today, we have an array of colours and effects. Some of the effects are known as Peonies, Chrysanthemums, Crossettes, Strobes, Willows and Palms.
Colours are usually created from pyrotechnic stars. These stars create intense light when ignited. They have five basic ingredients; a fuel which allows the star to burn, the colour which is a chemical to produce it, an oxidising agent, being a compound which chemically oxidisers the fuel, necessary for combustion, a binder to hold the compound together and a chlorine donor which helps strengthen the colour of the flame. Although, sometimes the oxidiser does this. Some of the colours that are used are red, produced by Strontium or Lithium, orange, produced by Calcium salts and yellow is created by Sodium. Barium creates the greens whilst Copper creates blue. The white you see is created by Titanium or Aluminium to name a few.
