Is there a green fire?

Summary

In this article, I will explore the phenomenon of green fire and answer some commonly asked questions about it.

Key Points

1. Is green flame hotter than blue?
The hottest part of the flame is the base, so this typically burns with a different colour to the outer edges or the rest of the flame body. Blue flames are the hottest, followed by white. After that, yellow, orange and red are the common colours you’ll see in most fires.

2. What flame burns green?
Copper compounds glow green or blue-green in a flame. Calcium compounds glow orange in a flame. Sodium compounds glow yellow in a flame.

3. What creates green fire?
Simply sprinkle copper sulfate onto the fuel, light it and enjoy the green flames! The copper is not consumed by the fire so if you are burning a clean fuel, you can reuse the copper sulfate again and again.

4. Why isn’t there green fire?
A normal flame is a black body emitter – relatively broad band, thus more likely to emit white light, if it was at a high enough temperature. Green does show up in this light, but because of the presence of red and blue in similar quantities, it doesn’t appear green but white.

5. Does black fire exist?
There is no way to create black fire because when it comes to light, black is the absence of light, not the mixture of all the colors light can produce.

6. What is the coldest fire color?
The colder part of a diffusion (incomplete combustion) flame will be red, transitioning to orange, yellow, and white as the temperature increases as evidenced by changes in the black-body radiation spectrum. For a given flame’s region, the closer to white on this scale, the hotter that section of the flame is.

7. Is green flame poisonous?
In all categories of aquatic toxicity testing, our GreenFire Wetting Agent received the best achievable EPA rating of “Practically Non-Toxic.” The included chart provides an easy-to-understand comparison between our product versus common products and substances.

8. Is green fire bad?
Not only does green wood not burn as hot, making it harder to heat your home, but it also causes excessive amounts of creosote to build up in your chimney at a dramatically faster rate. Creosote buildup is the leading cause of chimney fires, which are extremely dangerous and burn down thousands of homes every year.

9. Is green fire safe?
GreenFire Wetting Agent / Multi Class Foam is a class A-B fire protection product that is Fluorine and PFAS Free, non-toxic, and non-carcinogenic.

10. Does purple fire exist?
Purple flames come from metal salts, such as potassium and rubidium. It’s easy to make purple fire using common household ingredients. Purple is unusual because it’s not a color of the spectrum. Purple and magenta result from a mixture of blue light and red light.

11. Can a flame be black?
Light. So cool okay I’ve discovered something even cooler than just sticking the tissue in it if you drop a stream of the sodium chloride water in it then you get this black flame coming out of it.

12. What flame is hotter than blue?
Flame Colour Meaning
For example, a blue flame is the hottest…
