What Color Is the Hottest Flame?

Flames Come in Different Colors

When you think of a flame, you usually think of the bright orange and red glow that comes from a campfire. However, there are other colors of flames that can be produced under different conditions. It has been discovered that the color of the flame depends on the temperature of the combustion.

The Color of Flame Is Dependent on Temperature

Flames that are cooler will be orange, red, and yellow in color. As the temperature of the flame increases, it will turn bluish-white and then white. This is because as the temperature increases, more of the molecules in the flame will be ionized, or turned into ions. And the ionized molecules will give off a different color of light.

What Is the Hottest Flame?

The hottest flame color is blue. A blue flame is the hottest because it has a higher concentration of molecules that are ionized, or turned into ions. The blue color of a flame is usually produced when the temperature of the combustion is around 3,600 degrees Fahrenheit.

What Are the Cooler Flames?

Lower temperatures will produce different colors of flames. Red flames occur at about 1,900 degrees Fahrenheit, orange flames at about 2,400 degrees Fahrenheit, and yellow flames at about 2,800 degrees Fahrenheit. This means that the hottest flame color is blue, and the cooler flames will be orange, red, and yellow in color.

How Can You Create Different Color Flames?

Different colors of flames can be created by adding different chemicals to the fire. For example, adding a bit of salt to the fire will make it burn with a green flame. Adding a bit of copper sulfate to the fire will make it burn with a blue flame. And adding a bit of potassium chloride to the fire will make it burn with a violet flame. So if you want to create different color flames, you can do so by adding different chemicals to the fire.
