Luminescence the emission of light by a substance that has not been heated. Metals, such as aluminum, magnesium, and titanium, burn very brightly and are useful for increasing the temperature of the firework. The temperature of a firework can be controlled and with different components added such as charcoal, can be manipulated to be a desired color at the proper time. As a substance heats up it emits colors in different stages starting with infrared, then red, orange, yellow, and white as it becomes increasingly hotter. Incandescenc e is the emission of light caused by high temperature. There are two main mechanisms of color production in fireworks, incandescence and luminescence. Since the explosion throws the stars in all directions, you get the huge sphere of sparkling light that is so familiar at fireworks displays. The explosion ignites the outside of the stars, which begin to burn with bright showers of sparks. When the fuse burns into the shell, it ignites the bursting charge, causing the shell to explode. The stars are poured into the tube and then surrounded by black powder. They consist of black powder and ‘stars’ in a tight paper tube with a fuse to light the powder. Stars come in all shapes and sizes, but you can imagine a simple star as something like sparkler compound formed into a ball the size of a pea or a dime. They are often hand-held and generally safer then a firecracker firework!įirecrackers have been around for hundreds of years. Most fireworks that are sold in the United States are of the sparkler variety where they emit showers of colored flames, sparks, noises and other effects. There are 2 types of fireworks, the first is called a sparkler and the other is known as a firecracker. But how exactly do fireworks emit their colors and pops? Let’s find out below! Every year millions of people gather to view fireworks on the 4th of July.
