How Are Fireworks Colored?
Have you ever wondered how are fireworks colored? In this article, we will discuss the science behind it.
Each firework contains a specific combination of metals and salts that determine what colors will appear in the sky when the firework explodes.
As the metal strontium in fireworks emits red colors, barium is responsible for bright green colors and copper produces a combination of blue colors.
Similarly, chlorine causes some colors to glow, potassium nitrate and sulfur help ignite fireworks, and chlorate and nitrate provide oxygen for colorful explosions.
Other compounds are also added to these metals and salts to help the colors explode more widely.
A similar science applies to meteorites entering Earth’s orbit. As they enter orbit, their chemical composition causes them to glow in different colors.
