What’s Inside A Firework?

A lot of people love the spectacular display of light that fireworks put to the world. But, few people realize just how hard it is to design the lights that we have come to recognize and enjoy. Everything from the direction each sparkle takes to the colors that it shines in is created by hand in hopes of creating the most remarkable impression possible.

In the context of colors, let’s talk about two mechanisms responsible for colour production in any fireworks including incandescence and luminescence. We will also touch on the various substances that produce different colours to help you grasp the idea of what it takes to produce various colors in fireworks.


It is a process of light produced not by heat directly but rather through other means. This means that luminescence is a form of light that is produced at much lower temperatures in comparison to incandescent light , which is created directly from heat. In reality, it can be created at room temperature.

How does it work in the real world? Everything boils down the atoms. The process of producing luminescence involves giving an atom the ability to absorb energy. This, in the firework’s case, would be the energy that excites the atom itself. This causes the atom to emit energy in the form of photons, which our eyes absorb and convert into light. The color of the photon however depends on the wavelength of the light that is directly affected due to the intensity of that photon.


As we’ve said that luminescence is the process of an atom absorbing energy and sending it back out in the form of photons. This is distinct from incandescence, which is created directly by heat. As things get heated then they begin to glow, usually emitting certain lights like yellow, red, or orange, then white–the hottest type of light.

When fireworks are used, the glow is controlled through careful engineering and the use of different materials that allow the firework to reach the desired temperature to produce a particular glow. These substances used to produce glows include titanium and aluminium, both of which increases its temperature in the firework significantly and cause the glow to grow bright and bright, illuminating skies at night.

The chemicals that create the color

Since we’ve spoken about luminescence and incandescence, let us get into the various ingredients that are used to create various colors. This will give you an idea of the material that is used to create the luminescence shows we know and love and provide you with an understanding of what is required for the production of specific colors.

Red fireworks are usually created by using strontium or lithium salts. Green is produced by using barium compounds, which are combined with chlorine producer to keep the chemical stable. White is made by incandescence using aluminium to cause the glow to be very bright. Blue can be created using copper compounds. It is then combined with a chlorine producer in order to create the color. In the end, yellow is made through sodium nitrate and other sodium compounds.

In the case of any other color between, a mixture of two colors is employed to produce specific results. Purple, for instance will require the components that create green and red. However, it is evident how complex it is be to produce certain colours in addition to the time it takes for their burning and direction so that the light shows are impressive.


As you will see, the chemical process of fireworks can be complex. It takes a significant amount of time and effort to make top quality fireworks. And for the majority of these fireworks, this is evident in the cost. For that reason, if you want the best of the best fireworks that will light up the night, we recommend purchasing more expensive fireworks. The price is not only because of the dimension or complexity of the firework however, it is also due to the work that the manufacturer puts into it to ensure it provides the best possible experience!
