Every firework relies on a series of chemical reactions to achieve a certain size, color, or loudness. These chemicals are packed into a tube called an aerial shell that’s packed with chemicals and explosives. Here’s the ingredient list for a typical firework.
Sometimes called gunpowder, black powder helps the firework get into the air and blow up. Black powder is a mixture of sulfur, charcoal, and potassium nitrate (also called saltpeter). It’s used in two important parts of the firework process: 1. Gunpowder blows up below the firework and propels it into the air. 2. A fuse that’s designed to delay unt...
These are chemicals that help give fireworks their wide range of colors. Fireworks achieves certain colors and shades by applying heat to chemical compounds: 1. Red: strontium, lithium 2. Orange: calcium, calcium chloride 3. Yellow: sodium, sodium chloride (salt) 4. Green: barium, chlorine 5. Blue: copper, chlorine 6. Purple: mixture of copper (blu...
These are the small concentrations of explosives in a firework that blow up and fly in many directions when ignited. Notice how a firework looks like a bunch of long, bright light rockets? Each light results from a single “star” in the firework shell. Stars can also be arranged in shapes inside the aerial shell so that they look like happy faces, h...
Remember that fireworks are basically explosions of chemicals in solid form. Millions of combustion particles and gases are released into the air during these splashes of color on the sky. Many are also blown around for miles in atmospheric wind currents. The most notable fireworks pollutant, particulate matter (PM), includes three distinct types o...

Jul 2, 2024 · Any firework that produces smoke or colored light significantly contributes to Utah's air pollution, particularly given the two major firework holidays in July.
Finally, fireworks release a fine cloud of smoke and particulate matter, affecting local air quality. Some newer, ‘cleaner’ fireworks replace perchlorates with safer alternatives, or use compressed air to reduce smoke created. Read more: How are the colours and shapes of fireworks created?
