Celebration of Light 2006

Did you know?...In fireworks there are six common colours, made by adding a specific chemical compound. * White is produced by magnesium or aluminum or titanium * Yellow by sodium salts * Red by strontium nitrate * Green by barium nitrate or chlorate * Blue by copper compounds * Orange/amber by charcoal or other carbon or iron compoundsDeep blue and purple are the most difficult fireworks colours to create because they have a very narrow band on the colour spectrum, requiring the chemical reaction to be absolutely perfect. In fact, the creation of a deep blue flame remains one of the great unsolved challenges to pyrotechnicians. However, blue and green are considered the most dangerous colours to produce.
