Chemical Composition of Fireworks

The chemical reactions that firecrackers produce are an interesting feature of the explosives. Fireworks can also contain flash powder, which makes for a bright light and a loud bang. Firecrackers are attached to fuses that are made of threads that are mixed with gunpowder grains. When the compartments of fireworks explode, they produce the loud bang and bright light that we enjoy during celebrations. The most common type of fireworks includes the roman candle, sparklers, and rockets.

Chemical reactions

Fireworks create a spectacular display during Fourth of July celebrations. The metals that create the colorful fireworks are made by chemical reactions. These fireworks are composed of various metal salts that are excited in a high energy state. The energy released from the chemical reaction causes the fireworks to explode. A quick chemical reaction is necessary for explosive fireworks. Slow reactions will not produce the gas. The goal is to create a high-explosive gas quickly.

Common features

Fireworks are usually composed of a pasteboard tube and combustible material. Some fireworks have multiple tubes or cases, containing multiple colors and effects. A common type of fireworks are skyrockets and aerial shells. Festival balls are smaller versions of fireworks. The combustible materials that fireworks are made of are usually FRE, although some types are made of sheet steel. To avoid the risk of shrapnel, fireworks are manufactured with strict quality control.

Non-toxic chemicals

Fireworks are a common source of various heavy metals and sulfur-coal compounds. Barium, one of the primary colorants, is a known carcinogen, while copper compounds can cause irritation to skin and warts. Strontium, a common heavy metal used in fireworks, can cause birth defects and damage to bone marrow. Other chemicals in fireworks can cause respiratory problems and gastrointestinal problems. These substances should be avoided as much as possible, and the precautions should be taken when using them.

Artistic uses

Fireworks have long fascinated artists, and prints of these shows have been a popular medium for these works. Artists have always aimed to reveal fireworks, a fleeting and mysterious experience. Although the smoke emitted during a show is seldom shown as a background in engravings, the works by Bernard Lens II do show this. In the same way, Whistler’s painting Falling Rocket depicts the smoke emitted by the gunpowder barrels.

Legal classifications

There are various legal classifications for fireworks in the United States. Some fireworks are considered toy smoke devices while others are strictly prohibited. Depending on where you live, you can buy and sell fireworks in any category as long as you comply with the relevant laws. Listed below are legal classifications for fireworks. This list is not exhaustive. You should consult with your state law enforcement agency for specific requirements. Toy smoke devices are considered fireworks in some states, but not in others.
