The chemistry behind fireworks A Q&A with inorganic chemist Eric Schelter about the chemical reactions that create explosive displays and how different metals are used to create bright and brilliant colors. Barium chloride: Green color is produced by barium compounds that also aid to modify other volatile elements. Evaporation is a physical change. Chemical ingredients of fireworks are chosen to produce specific colors. The color blue is notoriously difficult to produce in fireworks, as the copper compounds need to be heated at a specific temperature for the optimal shade of blue to be produced. Add to Wish List. Magnesium burns a very bright white, so it is used to add white sparks or improve the overall brilliance of a firework.

Dicyanoacetylene, a compound of carbon and nitrogen with chemical formula C 4 N 2 burns in oxygen with a bright blue-white flame at a temperature of 5,260 K (4,990 °C; 9,010 °F), and at up to 6,000 K (5,730 °C; 10,340 °F) in ozone. Copper Sulfide CuS As are the other copper salts, this is also used in fireworks to add color. Oxidizers release excess oxygen . ( 2 customer reviews) $ 10.00 Per Pound. Their colors come from the different temperatures of hot, glowing metals and from the light emitted by burning chemical compounds. You need to use chemical formulas rather than common names of compounds in your table. The heat of the metal determines the color of the sparks. Potassium Perchlorate 325 Mesh 10 LBS. 3. These compounds create explosions. Copper chloride (blue), on the other hand, is unstable at high temperatures, so the firework cannot get too hot, yet must be bright enough to be seen.
