Pyrotechnics Pyrotechnics Bentonite is an absorbent aluminium phyllosilicate generally impure clay consisting mostly of montmorillonite, (Na,Ca)0.33(Al,Mg)2Si4O10(OH)2·nH2O. Two types exist: swelling bentonite which is also called sodium bentonite and non-swelling bentonite or calcium bentonite. It forms from weathering of volcanic ash, most often in the presence of water. Bentonite expands when wet - sodium bentonite can absorb several hundred percent of its dry weight in water. It is commonly used in drilling fluids, used to make slurry walls, and used to form impermeable barriers (ie plug old wells, as a liner in the base of landfills to prevent migration of leachate into the soil). ...more on Wikipedia about "Bentonite"
In pyrotechnics, black match is a type of fuse, constructed of cotton string fibers intimately coated with a black powder slurry. When black match is confined in a paper tube the flame front propagates much more quickly - this is called quick match. ...more on Wikipedia about "Black match"

In pyrotechnics a comet is a block of pyrotechnic composition attached to the outside of a shell, which burns and emits sparks as the shell is rising, leaving a trail in the sky. ...more on Wikipedia about "Comet (pyrotechnics)"
A firecracker (also known as a noisemaker or banger) is a small explosive device primarily designed to produce a large amount of noise, especially in the form of a loud bang; any visual effect is incidental to this goal. ...more on Wikipedia about "Firecracker"

A fireworks event (also called a fireworks display or fireworks show) is a spectacular display of the effects produced by firework devices on various occasions. Fireworks competitions are also regularly held at a number of places. ...more on Wikipedia about "Fireworks"
A flare is a type of pyrotechnic that produces a brilliant light or intense heat without an explosion. Flares are used for signaling, illumination, or defensive countermeasures in civilian and military applications. ...more on Wikipedia about "Flare (pyrotechnic)"
A gerb is a type of firework which produces a jet of sparks, usually from 30 to 120 seconds. It is a thick-walled tube filled with pyrotechnic composition and possessing a choke, which is a narrowing in the tube. Gerbs are often referred to as 'fountains'. ...more on Wikipedia about "Gerb"
A nozzle is a mechanical device designed to control the characteristics of a fluid flow as it exits from an enclosed chamber into some medium. Frequently the goal is to increase the kinetic energy of the flowing medium at the expense of its pressure energy. A nozzle is generally a pipe or tube of varying diameter, and it can be used to direct or modify the flow of a liquid or gas. Nozzles are frequently used to control the rate of flow, direction, and/or the pressure of the stream that emerges from them. ...more on Wikipedia about "Nozzle"
A propellant is a material that is used to move an object by applying a motive force. This may or may not involve a chemical reaction. It may be a gas, liquid, plasma, or, before the chemical reaction, a solid. Common propellants are gasoline, jet fuel and rocket fuel. ...more on Wikipedia about "Propellant"

Pyrotechnic stars are pellets or simply pieces of pyrotechnic composition which may contain metal powders, salts or other compounds that, when ignited, burn a certain colour or exude a spark effect. They are a part of all projectile type fireworks. The most common is the aerial shell. When you watch this firework, it will launch into the sky, burning a lifting charge. Once the shell has attained proper altitude, due to other mechanisms within the firework, it will ignite the stars. ...more on Wikipedia about "Pyrotechnic star"
Pyrotechnics is a field of study often thought synonymous with the manufacture of fireworks, but more accurately has a wider scope that includes items for military and industrial uses. Items such as safety matches, oxygen candles, explosives bolts and fasteners, and the automobile safety airbag all fall under the purview of pyrotechnics. ...more on Wikipedia about "Pyrotechnics"

A Saturn Missile Battery is a popular consumer fireworks device that launches small, self-propelled whistling projectiles into the air, which explode at their maximum altitude. Saturn Missile Batteries come in 25, 100, 200, 300, and 750-shot sizes. ...more on Wikipedia about "Saturn Missile Battery"
Smoke bombs are a firework designed to produce colored smoke upon ignition. While there are smoke generating devices that are dropped from airplanes, the term "smoke bomb" is typically used to describe the three varieties of smoke devices: ...more on Wikipedia about "Smoke bomb"

A squib otherwise refered to as an electric match is a small explosive device which is used in pyrotechnics and display fireworks. A squib can range in size from a small cap only millimeters in diameter to larger, more spectacular ones which can be 1/2 inch or larger. In display fireworks, it is used to ignite the fuse of a commercial firework shell. The squib is generally connected to a "firing-rail" or "breakout box" which connects to a central firing board. Squibs are designed to be fired using a small current which can be supplied from sources such as a 9 volt battery or a 12 volt car battery in larger setups. Squibs are also very sensitive to EM radiation and devices such as vehicles, radios, cellular phones, and even cellular and microwave transmitters can set off a squib unless the two leads are terminated correctly. ...more on Wikipedia about "Squib (explosive)"

Tracers are special bullets that are white phosphorus-tipped or contain a powder in their base that burns very brightly during their flight. This enables the shooter to follow the bullets' trajectories. The shooter then, typically, "walks" his cone of fire onto the target by seeing where the tracer is going. Tracers have been used extensively in machine guns since World War I ( 1914- 1918) and are usually loaded at a ratio of one tracer per four rounds in ground guns, and one tracer per every two or three rounds in aircraft guns. ...more on Wikipedia about "Tracer ammunition"
Very flares (named after E. W. Very, 1847–1907, US inventor) were signal flares, fired from a hand-gun, used during World War I and World War II (and still used today). They were produced in three color variants: green, red, and " white star". The flares come in two sizes, 26.5 mm and 38 mm; both sizes have a "burn time" of ~5 s. ...more on Wikipedia about "Very flare"
Visco fuse is required for all consumer fireworks. It is the fuse that, most commonly in green, is found as a twisted, coated, strand. It can also be used to create delays in the rate of firing multiple fireworks linked together. It is a cord with a black powder core. There are three layers to visco fuse. First one layer of string is wound around the core, then a second, less tight layer of string is wound in the opposite direction to prevent unraveling. The last layer is a low-nitrate nitrocellulose lacquer. The last layer is to water-proof the strand and to prevent it from falling apart. ...more on Wikipedia about "Visco fuse"
