The chemical process of converting a compound or mixture into another chemically stable form. Decomposition is usually accompanied by the production of heat.
An electric match is a device that is used to ignite fireworks using electrical current. Approximately one inch in length and ¼ inch round, these items usually consist of a small nickel-chromium wire with a pyrogen coating. An electrical current causes the nickel-chromium wire to heat up, igniting the pyrogen and starting the fuse. Typical manufacturers of these devices include Oxral and Davey Fire.Explosive
A substance or mixture which, when submitted to shock, friction, sparks, or flame, can undergo rapid decomposition with the production of a considerable quantity of heat and large volumes of gas.
A beautiful aerial effect that consists of glowing embers that tumble slowly in the air, flickering back and forth as they fall back to earth.Firecracker
A fireworks item containing flash powder and wrapped in paper with a fuse attached. When the fuse is lit, it burns down inside the paper until it reaches the flash powder.

A term for a device that spins very fast and lifts high into the sky, only to explode or burst into a special aerial effect. These are also called planes, sky flyers or UFOs.High Explosives
High explosives are extraordinarily powerful substances that can release large amounts of energy and heat. They can be detonated by a sufficiently large mechanical or explosive shock, and generally require the use of an initiator to start the detonation. Examples of high explosives include TNT, nitroglycerine, RDX and PETN. High explosives are not used in fireworks
Illegal fireworks include any firecracker with more than 50 milligrams of flash powder, such as the original 1960’s version of the M80, cherry bomb, silver salute, or quarter stick. Consumer fireworks also may not contain any chlorates, red phosphorus, high explosives, more than 130 milligrams of flash powder in an aerial report, or more than 500 grams of total composition.Initiator

A tube of pyrotechnic composition, usually five inches long, that burns for one minute. Lances come in various colors are used in set pieces for fireworks events. See the definition of set piece below.Low Explosives
These are explosives that burn at a steady speed and can only be detonated under extreme circumstances (if at all). Low explosives are generally used as propellants, and are seldom used in demolition work. Examples of low explosives are black powder and fireworks.
The original M80 was a military simulator that was sold as a firecracker. M80s are red in color, one and one-half inches long, 5/8 of an inch in diameter, with a green waterproof fuse sticking out the side. It contained two grams of flash powder and was responsible for hundreds of serious injuries due to its powerful blast. These items were banned by the CPSC in 1966, and made illegal by the BATF (now ATFE) in the 1970’s. Legal M80’s today contain 50 milligrams of flash powder, which is about 1/40th of the original M80. Illegal M80’s sometimes contain compositions that are sensitive to shock and can injure of kill people. If you like having full use of your fingers, hands, and eyes, don’t mess with illegal M80’s.Mine
An aerial device that shoot stars into the sky in an upward spray pattern.Missile
In fireworks, a missile is a sky rocket that does not have a stick for guidance. Instead, it may rotate to give it some stability as it lifts off, or may be shot from a tube (like Saturn Missile Batteries).
An abbreviation for the National Fire Protection Association. The NFPA is responsible for setting uniform national standards for fireworks use, manufacture transportation, and storage. NFPA 1122 sets standards for Model Rocketry. NFPA 1123 sets standards for using display fireworks. NFPA 1124 sets standards for manufacturing and transporting fireworks. NFPA 1125 sets standards for manufacturing model rockets. NFPA 1126 sets standards for the use of proximate (indoor) fireworks. NFPA 1127 sets standards for the hobby of high-power rocketry.Novelty

The original quarter sticks were similar to M80’s, but were larger in size and contained 10 grams or more of flash powder. Quarter sticks were silver in color, four inches long, one inch in diameter, with a four inch green waterproof fuse sticking out the side. These items were so powerful that they could dismember and kill people who misused them. Quarter sticks were banned by the CPSC in 1966, and made illegal by the BATF (now ATFE) in the 1970’s. Legal quarter sticks today contain 50 milligrams of flash powder, which is about 1/200th of the original quarter stick. Illegal quarter sticks can contain compositions that are extremely sensitive to shock and can injure of kill without warning. The ATFE imprisons people that are caught with illegal quarter sticks.Quick Match
Quick match is a type of fuse that is used to light commercial fireworks. It consists of black match that is wrapped loosely in a paper pipe, approximately 3/8 on an inch in diameter. While black match burns at a rate of one inch per second in the open air, quick match burns at a rate of approximately sixty feet per second (very fast). See the definition of black match (above) for more information.
A reloadable aerial is an aerial mortar that includes one or more mortar tubes and several reloadable aerial shells. The shells are placed inside the mortar tube, a long quick-burning fuse is lit, and the item is fired into the sky. These items are consumer versions of the mortar-based fireworks used in commercial fireworks displays.Repeater
Sometimes referred to as “cakes” or “multi-shot aerials”, a repeater is a cluster of aerial tubes with a single fuse. The name “cake” was attributed to these because the cluster of tubes looks similar to a cake in size and shape. Once the fuse is lit, each of the tubes is fired in sequence. Cakes can have a variety of intricate aerial effects, including spinners, fish, flower bouquets, comets, crossettes, reports, and other aerial effects. Cakes are the most popular consumer fireworks items outside of sparklers and firecrackers.Report

A term for a device that spins very fast and lifts high into the sky, bursting into a special aerial effect. These are also called helicopters, planes, or sky flyers.
Visco is a type of rugged waterproof fuse that is used to light fireworks. Most visco fuse is green in color, but is available in almost any color. Because visco fuse is known to spit fire when it is lit, you should never light visco directly with a match or anything that would put your fingers in close proximity to the fuse. Instead, visco should be lit with a propane torch, a road flare, or a long punk.
A wheel is a stationary device that spins and creates a circular ring of fire and sparks. These are generally nailed to a pole or a tree before they are lit. You should always be careful to make sure the area is free from flammable debris before you light a wheel, as the sparks can carry ten feet or more.Whistle
Whistles are generally small paper tubes filled with a composition that makes a sharp howling sound. Whistles can be found in rockets, fountains, cakes.Wholesale Fireworks
