The Chinese

Although no one is for certain when fireworks actually were created, experts do know that they were developed in ancient China, during the Han dynasty (about 200 B.C.) long before the rest of the world had any knowledge of them.

the first time
The First Time
  • It is believed that the first firework was actually a chunk of green bamboo that someone threw into a fire. The “firecracker” began to sizzle and eventually ended with a loud POP!

The Chinese developed two of the major components in fireworks. They invented paper and the substance which causes the explosions, gunpowder. However, gunpowder was developed long before guns or combustible firearms were developed.

how to make gunpowder
How to Make Gunpowder
  • Gunpowder is simply a mixture of carbon, sulfur, and saltpeter.
  • Carbon can be found as pure charcoal.
  • Sulfur can be found in any gardening store.
  • Saltpeter can be found in some drugstores, or gardening stores.

  • Each substance must be ground into a powder and then mixed together.
  • We will be using a ball mill with lead balls to grind the gunpowder.

The Process.


  • When mixed with the charcoal, the saltpetre burns rapidly producing glowing sparks. If you add some sulfur to the mix, it will burn even more hastily, producing smelly smoke. If you place the mixture inside a tube of paper and light it, a fiery jet is produced
the process cont d
The Process Cont’d…
  • Chinese most likely developed fireworks because they enjoyed making loud noises at religious ceremonies and festivals.
  • Charcoal is a black solid, which is created when wood is heated in a fire.
  • It is the first of the three ingredients that are crucial to making gunpowder.
  • The next ingredient is Sulfur, an often crumbly yellow substance that can be found in many parts of the world.
  • When sulfur is burned it puts off a bluish flame and an awful smell similar to rotten eggs.
  • The final main ingredient is saltpetre.
  • Saltpetre is a white powder resembling salt.
  • When put into a fire, it burns very furiously.

Fireworks Safety

• Only buy fireworks marked BS 7114.• Don’t drink alcohol if setting off fireworks.• Keep fireworks in a closed box. • Follow the instructions on each firework.• Light at arm's length, using a punk.• Stand well back.

• Never go near a firework that has been lit. Even if it hasn’t gone off, it could still explode.• Never put fireworks in your pocket or throw them.• Always supervise children around fireworks.• Light sparklers one at a time and wear gloves.• Never give sparklers to a child under five.• Keep pets indoors.

Fireworks Safety Continued…

Black powder is one of the most dangerous explosives because it ignites easily by heat, friction, or spark.

In 2005, almost half of injuries caused by fireworks were to children under 18.



The art of firework creating

color production
  • Colors are produced by heating metal salts that emit characteristic colors
  • Atoms of each element absorb energy and release it as light of specific colors
  • Energy absorbed by an atom rearranges its electrons from ground state
  • Excess energy of excited state is emitted as light, as electrons descend to lower-energy states
  • Amount of energy emitted is characteristic of the element and the amount of energy determines firework color
color production1



Light NOT produced from heat

Electron of atom or molecule absorbs energy, becoming unstable

Photons (light) released when electron returns to lower energy state. Photon’s energy determines its wavelength (color)

  • Light produced from heat
  • Heat causes substance to become hot and glow: emitting infrared, then red, orange, yellow, and white light as it becomes hotter
  • When temperature is controlled, glow can be manipulated to desired color (temp.) at the proper time
  • The tremendous booms heard are the result of the rapid release of energy into the air, causing the air to expand faster than the speed of sound, producing a shock wave or a sonic boom
most popular fireworks
Most Popular Fireworks:
  • Firecrackers
    • Gunpowder wrapped in paper w/ a fuse
  • Sparklers
    • Chemical mixture molded onto a rigid stick or wire
  • Rockets & Aerial Shells
    • Gunpowder based
    • Some modern ones use compressed air as propellant and an electronic timer to explode
Gunpowder: 75% potassium nitrate, 15% charcoal or sugar, 10% sulfur

Component in gunpowder react when heat is applied (lighting the fuse)

Charcoal or sugar is the fuel

Potassium nitrate is the oxidizer

Sulfur moderates reaction


Fuel: charcoal and sulfur

Binder (holds mixture together): sugar or starch

Mix in water, forming a slurry that can be coated on wire or poured into a tube

Once dry…BAM!! You have a sparkler

Fuel and oxidizer are proportioned so it burns slowly for several minutes of fun!

aerial shells
A tube containing gunpowder is lit with a fuse

Gunpowder is used to propel firework in the air

A hole at bottom of firework lets expanding N and CO2 launch into sky

Packing of gunpowder, more oxidizer, and colorants determines shape
