How Fireworks are Made?

Fireworks generally have different parts and making of fireworks has several steps. They usually have housing that holds everything together, “stars” - which are chunks of a mixture of chemicals and its purpose is to produce light and color when heated, and gunpowder that propels stars out of the housing when ignited.

Making of fireworks begins with making of stars. Material for stars is weighed and sifted twice through brass screens to remove lumps. Brass screens are used because brass does not produce sparks which could ignite everything. After sifting, ingredients, which are in powder, are mixed by hand or in a machine that has rotating drum or a stationary container with paddles that rotate. Great care is taken not to cause heat from friction. Water is mixed with a resulting powder mixture until soft dough is made which makes it safer for manipulation and easier for molding. Dough is molded into loaves and placed on the working table that is covered in gunpowder. Pressed there, it is cut into dice 0.16-5 cm in size which are covered with gunpowder that will help them to burn once they are ignited. They are left there to dry which makes them stars.

Stars are then placed into cardboard container that has a cardboard tube in the middle. When all the stars are placed in the container, gunpowder is poured through a carbon tube and between the stars. Filled container is closed which makes him a “break”. To make a break stronger, cardboard container is “spiked” - wrapped with heavy string. Some breaks are made from plastic or heavier cardboard and does not need to be spiked. Time fuse is added to a break which will explode the break after it is launched. Break is then allowed to dry for two days which makes its structure stronger.

After they are dried, breaks are assembled into shells. Simple ones are made from one break and one compartment of gunpowder and different technologies make for different types of shells. Asian shells are round and have only one break while European and American are cylindrical and can have many breaks. These will display multiple bursts of different colors when they explode. Usually, they are made of a small compartment of black powder, three or four colored breaks, and a salute which make a loud bang but no light. Large ones can have as many as 10 breaks and the largest one known had 22 breaks. All components are stacked together, then a fast fuse us added and everything is wrapped in heavy paper. This makes firework finished.

Smaller fireworks, which are intended for private use, are simpler in construction and contain less explosive. They can be shaped like paper tubes holding a small amount of explosive like firecrackers or shaped like paper cones which are filled with chemicals which release colored sparks when ignited like fountains. Others are Roman candles, which have several large stars in a cardboard tube which fire at a regular interval; smoke balls that emit just smoke and have no explosive parts; or snakes that produce a long tail of ash.
