Fireworks display is both an art and science,
refined into beautiful art-forms rich of sensations,
to be technically unfolded airborne on the nocturnal
sky backdrop.
The darker the sky, the brighter illuminations the
fireworks.
It is not over-claimed
to say that almost every body loves fireworks extravaganza!
The secret
formulas of fireworks manufactures have long been
treasured by pyrotechnic families in various parts
of the world since the ancient days, in addition to
accumulative technologies their younger generations
endeavor to seek after toward
maximal perfection
Fireworks use such low explosives
as gunpowder or black powder to fire the shells from
their mortars, which lift charges are ignited electrically.
When the lift charges
explode, the shells shoot out from the mortars up
into the air. Within the shells are cores where other
exploding charges with delay fuses are built-in. When
the shells are fired from mortars, they in turn ignite
the delay fuses, which are cut to lengths that will
set off the explosive charges inside the shells at
the right heights and at the right timings.

The explosive charges at the centers or cores are
made of black powder or flash powder which, upon ignitions,
creates violent explosions combined with flashes.
Their explosions send burning stars out in particular
patterns determined by the ways the shells were packed
by the bomb manufacturers
– The results: The colorful airborne
effects the crowds enjoy watching them.
In short, fireworks
or pyrotechnics can be classified into two
major categories;
Class B for
professionals, and Class C. for consumers.
Similarly, Class B can be generally termed as Articles
Pyrotechnic, 1.3 G. and Class C. as 1.4 G. ranging
from indoor pyrotechnics to toy fireworks. These classifications
are only generic, which
stipulations may differ from place to place, state
to state, or country to country.
To operate any 1.3
G. fireworks displays, only professional pyrotechnic
personnel are permitted to perform such aerial fireworks
displays, based upon austere safety measures in all
respects.
To SIFCO,
safety precautions have always been our primary factors.
