Chemistry of Firework Colors – ThoughtCo

Incandescence. When the temperature of a firework is controlled, the glow of components, such as charcoal, can be manipulated to be the desired color (temperature) at the proper time. Metals, such as aluminum, magnesium, and titanium, burn very brightly and are useful for increasing the temperature of the firework.

How fireworks work | Firework science – Explain that Stuff

Traditionally, gunpowder used in fireworks was made of 75 percent potassium nitrate (also called saltpeter) mixed with 15 percent charcoal and 10 percent sulfur; modern fireworks sometimes use other mixtures (such as sulfurless powder with extra potassium nitrate) or other chemicals instead.

The chemistry behind a firework explosion – The Verge

Jul 03, 2015 · Fireworks utilize a precise chemical mixture. The fuse used to light the tiny rocket is made of very fine gunpowder, which allows the wick to burn at a very controlled rate. This gives whoever lit the firework some time to get out of the way. The burning fuse then lights much larger granulations of gunpowder at the bottom of the firework. That explosion carries the rocket into the sky.


Fireworks! – American Chemical Society

Jul 02, 2006 · An aerial shell is made of gunpowder, which is a well-known explosive, and small globs of explosive materials called stars (Fig. 1). The stars give fireworks their color when they explode. When we watch fireworks, we actually see the explo- sion of the stars.

The Chemistry of Fireworks | Compound Interest

The colours in fireworks stem from a wide variety of metal compounds – particularly metal salts. ‘Salt’ as a word conjures up images of the normal table salt you probably use every day; whilst this is one type of salt (sodium chloride), in chemistry ‘salt’ refers to any compound that contains metal and non-metal atoms ionically bonded together.
