What makes fireworks different colors and have different sounds?
The multitude of firework colors are achieved by varying the different metallic salts or oxides added to the mix. The fuel and oxidizing agent together make an intense amount of heat very quickly which activates or heats up these metal colorants. Orange fireworks are the result of calcium salts.
What color is hardest to make?
Blue
Blue is the most difficult color to make, and we found it extremely stable, so that made me really excited, and we find this to be the first new blue pigment in 200 years.”

How are the different firework shapes produced?
The shape comes down to the construction of the firework’s shell (container) and the arrangement of the exploding stars (pyrotechnic pellets) within them. Arranging the stars into the desired shape on a piece of card within the shell makes them explode outwards in that pattern.
What is the blue color in fireworks?
Copper compounds
Copper compounds produce blue colors in fireworks. Iron is used to produce sparks. The heat of the metal determines the color of the sparks. Potassium helps to oxidize firework mixtures.
What are green fireworks?
It has been explained that green crackers don’t contain aluminium, barium, potassium nitrate or carbon, making them eco-friendly. According to P Ganeshan, president of the Tamil Nadu Fireworks and Amorces Manufacturers Association, green crackers are 30 percent less polluting compared to ordinary ones.
Why are there no blue fireworks?
Bright blue fireworks are far more challenging to produce than common colors like red, white, or green. The issue is that the chemical compound that makes that brilliant blue is more fragile that that of other colors, breaking down at high temperatures.
What metals make firework Colours?
Mineral elements provide the color in fireworks. Barium produces bright greens; strontium yields deep reds; copper produces blues; and sodium yields yellow.
Why do all fireworks look different?
Once the firework is in the sky, the gunpowder within the firework ignites. The pattern of stars around the central gun powder charge creates different patterns of fireworks. For example, if the stars are in a circle around the black powder charge, you get a circle display of colour.
What causes fireworks to burn in different colors?
A pyrotechnic colorant is a chemical compound which causes a flame to burn with a particular color. These are used to create the colors in pyrotechnic compositions like fireworks and colored fires.
What do the colors produce by fireworks indicate?
The bright, colorful part of the fireworks display is caused by “excited” electrons in the atoms of different metal and salt compounds. These compounds are in little balls called stars, made of a similar compound to what makes a sparkler work. Different metals burn in different colors.
Where do the different colors of fireworks actually come from?
The colors in fireworks come from a simple source: pure chemistry. They’re created by the use of metal salts. These salts are different from table salt, and in chemistry ‘salt’ refers to any compound that contains metal and non-metal atoms.
Why do fireworks have different colours?
There are two main mechanisms of color production in fireworks, incandescence and luminescence. Incandescence is the emission of light caused by high temperature. As a substance heats up it emits colors in different stages starting with infrared, then red, orange, yellow, and white as it becomes increasingly hotter.
