An effect of periodic burning giving the effect of flashing or strobe


Spanish for little shell. Usually found as part of roman candles or cakes and occasionally in mines or sub components of shells

Bottom fused

The normal method of igniting a shell. The delay is ignited which then lights a delay fuse on the shells. Also used for cakes when the fuse runs round the base of each tube and enters via a small hole

Bursting Charge

An internal charge of a shell or bombette unit that breaks the shell open at a predetermined height. Made from gunpowder or flashpowder


A burst of a cylindrical tube from a central point which creates an effect that looks like the wings of a butterfly


Colloquial term for a multi shot battery


The inside diameter of a firing tube or mortar


An aerial shell containing several shells that explodes at the same time. Also a battery of reports from china


The tube that contains firework composition

Catherine wheel

The traditional name for a wheel. The name given because of St.Catherine who was martyred on a burning rotating wheel

Chain fusing

A method of fusing several firework elements together e.g. shells

Chinese cracker

A roll of many hundreds of individual cracker units which produces a machinegun report effect when hung up. Traditionally used for Chinese celebrations


The narrowing of a tube usually for fountains or rockets by means of squeezing the tube or the insertion of a clay bung

Chrysanthemum break

A spherical burst in which each star leaves a visible trail

Closed circuit

A completed electrical circuit. i.e. A ready to fire circuit

Coconut break

A shell containing large stars usually gold, silver or crackling to produce a palm tree effect. Usually fitted with a tail to produce the trunk effect


A solid unit of composition usually used in roman candles. The unit is completely self consuming so is useful for site where fallout is a problem


A term used for all pyrotechnic mixtures. More specifically it is a list of ingredients in a particular mix. All compositions contain an oxidant together with colour or effect ingredients.


A specialised fountain in the shape of a cone. A burning cone will increase the height of the spark shower as it burns as the surface area that burns is increased.


Banger unit also see Chinese cracker


An effect containing hundreds of sharp bangs thrown off a low intensity comet. Most crackle compositions contain lead or bismuth oxides


See Screecher

Cross match

A piece of thin raw match used to facilitate the ignition of a shells internal delay fuse. Usually made from splitting or punching the delay fuse


See Splitting comet

Crossing stars

Two stars in a single tube with a central bursting charge


See Kimuro

Crown chrysanthemum

A chrysanthemum break with longer burning stars that fall to the ground. Often produced to have coloured tips at the end.

Crown wheel

A plastic ring with driver units that rotate and flies vertically. Double acting versions are available which ascend drop sand then re ascend

Cylinder shell

Usually European and commonly a stack of shells that are timed to break in a sequence.


A shell with larger and brighter stars than peony breaks


Explosive propagation which is faster than burning but is not detonation


Pyrotechnic composition that burns at a predetermined rate and used for timing within or externally between fireworks

Delay fuse

A pyrotechnic composition designed to delay before functioning the next explosive device. Most commonly used in shell spikes as they rise into the air.

Display area

The are used for rigging and including the safety and fallout area


A specialist gerb with more power whose primary purpose is to rotate a wheel. Often including titanium.

Electric match

An electric igniter

European standard

A proposed standard for fireworks across Europe (CEN 212) currently being adopted across Europe.


Any material that is capable of undergoing a self contained self-sustained exothermic chemical reaction at a rate that is sufficient to produce substantial pressures on their surroundings thus causing physical damage. All fireworks are classified as explosives

Explosive train

The progress of fire from one explosive component to another.

Fallout zone

A safe area designated for any debris fallout from a display. This must be selected with climatic conditions in mind.

Finale barrage

A rapid firing pre fused sequence fired at the end of a display


See Cracker


An explosive assigned to UN numbers 0333 to 0337.
