4G Explosives

Formerly known as Class C common fireworks. Items classified as 1.4G explosives are consumer fireworks intended for use by the general public.

Barrage

A rapidly fired sequence of aerial fireworks.

4G Explosives

A cartridge containing pyrotechnic composition, a burst charge, and an internal time fuse or module that is propelled into the air from a mortar.

Battery

A collection of fireworks devices, such as a group of mortars (finale battery) or a bundle of Roman candles (candle battery), fused together in such a manner that they are fired within a short period of time.

Lift Charge

The composition that propels (lifts) the pyrotechnic device into the air.

Comet

A pellet of composition that is propelled from a mortar or shell and produces a long-tailed effect. Large comets are constructed much like aerial display shells, with an attached lift charge ready for loading into mortars.

Mine

A device containing multiple pyrotechnic effects that are simultaneously ignited and dispersed into the air from a mortar or tube.

Mortar

A tube from which certain aerial devices are fired into the air.

Roman Candle

A chain-fused firework that propels a series of aerial shell, comet, or mine effects into the air from a single tube.

Novelty

A device containing small amounts of pyrotechnic and/or explosive composition but does not fall under the category of consumer fireworks. Such devices produce limited visible or audible effects. Examples are snakes, tanks, poppers, and snappers.

single shot mortar

Usually a pre-loaded tube that contains one shot of various aerial effects. This is not reloadable.

report

A component of an aerial display shell or mine. A report contains salute powder, a powerful pyrotechnic composition (usually flash powder) that explodes violently, producing a loud noise with the visual effect of a bright flash and smoke.

500 gram multi-shot aerial (cake)

This is a large, multi-tube aerial firework. This has more than one shot with only one fuse. It is packed with 500 grams of powder divided among the lift charges and aerial shells, which is the maximum amount of powder allowed on any multi-shot device per federal law.

350 GRAM MULTI-SHOT AERIAL (CAKE)

This is a medium-sized, multi-tube aerial firework. This has more than one shot with only one fuse. It is packed with 350 grams of powder, divided among the lift charges and aerial shells.

Sparkler

A type of hand-held firework that burns slowly while emitting colored flames, sparks, and other effects.

200 GRAM MULTI-SHOT AERIAL (CAKE)

This is a smaller, multi-tube aerial firework. This has more than one shot with only one fuse. It is packed with 200 grams of powder, divided among the lift charges and aerial shells.

Fountains

A ground firework that emits showers of sparks upwards. You are able to distinguish a fountain from an aerial firework by its warning label, which reads, “Emits Showers of Sparks.” Fountains come in all shapes and sizes; they spray at different heights, and some of them also produce an audible effect.

reloadable mortar (artillery shell)

Reloadable mortars are firework shells that have both different effects on them as well as different sizes. All reloadable shells come with their own tubes that are made of either fiberglass, H.D.P.E. (high-density polyethylene), or cardboard. Canister-shaped shells contain 60 grams of powder and are 1.75 inches wide. They are shot out of a mortar and may have single or multiple breaks.
