What Is The Process That Makes Fireworks Explode?

Millions have enjoyed fireworks throughout the centuries and millions have also wondered how these beautiful, controlled explosions actually work. The answer is simple chemistry.

From their inception in ancient China to their evolution in 1800s Italy, fireworks have fascinated us.

The Anatomy of Colorful Fireworks Displays

Simply put, fireworks are set off by igniting a fuse at the end of each tube. The fire travels to the center of the firework tube known as the shell casing. This sets off the black powder charge that enables it to lift vertically into the air.

The shell is filled with pellets known as stars. These pellets contain metal salts and other chemicals that create the various colors seen in the sky during fireworks displays.  When the firework shell reaches a pre-determined height, the timed fuse ignites activating the burst effect that explodes the pellets. 

How the Colors Are Created

The stars or pellets contain specific chemicals creating different colors. Below are some examples of the chemicals used to produce the colors we know and love:

• • Calcium – Orange
• • Barium – Green
• • Copper – Blue
• • Strontium – Red
• • Sodium – Yellow
• • Strontium & Copper – Purple
• • Magnesium, Titanium, and Aluminum – White

Various combinations of chemicals in segmented areas of the tube explode at timed intervals to produce the multi-color displays that mesmerize us.

The Result Is Magical

Whether you’re interested in chemistry or not, fireworks are one of the most widely enjoyed events in our lives. Nothing says celebration like a sky filled with bright colors as far as the eye can see.
