Earlier, the people enjoyed the sound more than the show. After many years, people discovered that the greater amounts of oxygen in chemical compounds made the fireworks brighter and stayed for a longer time. First, the fireworks were orange and white. New colours were made by adding different minerals. In the 1800s, fireworks developed into what we know today. Italy was the first country that experimented with pyrotechnics.
