What causes a green flame 2024
In non-pyrotechnic flames, the most common reason for a green color is the presence of copper. As copper heats up, it absorbs energy that manifests as a green flame.
Other causes of green flames include:
- BoronA less common cause of green flames is the presence of boron or a boron compound.
- Barium compoundsIn pyrotechnic flames, such as fireworks, green flames are always made with barium compounds and a source of chlorine.
- Stray copperCopper can cause green and blue flames in other settings, such as wood with copper-based fungicides, paper with copper in the ink, or copper staples.
- Ammonia gasAmmonia gas burns with a pale yellowish green flame.
Green flames can also be caused by copper salts or corroded copper parts contaminating the flame with copper ions. This can happen naturally, and the minute amount of copper is harmless. However, if someone intentionally puts larger amounts of toxic copper salts there, that might be dangerous.
Flares, fireworks, and decorative fireplace logs use copper to create green colors. And stray copper can cause green and blue flames in other settings, for example, wood with copper-based fungicides or paper with copper in the ink or copper staples
A green flame in a fire or combustion reaction is often the result of the presence of certain chemical elements. The color of a flame is influenced by the specific elements or compounds that are burning and the energy levels of the emitted photons. Here are common causes of a green flame:
- Copper Compounds:
- The most common reason for a green flame is the presence of copper compounds. When copper is heated, it can emit a green color. For example, copper sulfate or copper chloride added to a fire can produce a green flame.
- Borate Compounds:
- Boron compounds, such as borax (sodium borate), can impart a green color to a flame. Boron can emit green light when heated.
- Barium Compounds:
- Barium compounds, like barium chloride or barium nitrate, can also produce a green flame. Barium emits green light when burned.
- Thallium Compounds:
- Thallium, a less common element, can produce a green flame when it is present in certain compounds. However, thallium is toxic, so caution is needed when using it for flame coloration.
It’s important to note that the color of a flame is determined by the specific energy levels of electrons in the atoms or ions present in the burning material. When these electrons are excited and then return to their lower energy states, they release energy in the form of light. Each element emits light at specific wavelengths, resulting in characteristic flame colors.
If you observe a green flame and are unsure of the cause, it’s essential to exercise caution. Some substances that produce colored flames may be toxic or pose other hazards. Always follow safety guidelines and use appropriate protective measures when experimenting with flame coloration. Additionally, be aware of local regulations and guidelines regarding the use of certain chemicals.
Borax or Boric Acid Green Fire
Borax and boric acid are two boron salts. … Adding either chemical to a fire yields a vivid green flame. For best results, mix borax or boric acid with methanol, a type of alcohol, and ignite the solution. The alcohol will burn off, leaving behind a white residue from the boron compound.
The most common cause of a green flame is the presence of chemicals containing copper inside the fire.
When copper is heated up (for example, by being in a hot fire) it can absorb energy in a process called “atomic excitation.” The electrons in the copper atoms move to new positions. But then later, the copper atom gets rid of the energy: its electrons go back to the normal positions and it releases the extra energy as light. The colour of the light released when the copper goes back to normal is the exact same colour every time, it’s based on the natural positions of the electrons inside the atom. So for copper, it’s always green or blueish green light. For other elements, it’s other colours.
What causes a green flame 2024
This is pretty handy for chemistry sometimes: you can heat a small amount of a mystery substance in a fire, and the colors it makes will tell you some of the atoms that are inside it, which is called the “flame test”. Wikipedia has a great list of what colors different elements turn to fire.
This website has really nice pictures of flame tests.

(Boron, barium, and tellerium are also green in a fire, different shades of green than copper, but they’re less common than copper so if you’re just noticing a random green fire it’s probably copper.)
Copper chemicals are used to make green fireworks. You can also buy a little packet of copper chemicals (mostly copper sulfate) to throw into a bonfire and make it turn green for a while. I’ve used this brand and it works pretty well, but copper sulfate is poisonous so you should definitely follow the directions on the packet about how long to wait to cook on the fire after you use it.
Is it safe when my gas fire flame is green?
As everyone else is saying, it usually means there’s contamination of the gas line. The most probably culprit is oxidized copper.
Gas lines for a fireplace are normally made of steel or iron. Copper is a poor substance because of its low resistance to heat. Although the flame doesn’t occur inside the copper line, it occurs close enough to heat the pipe up and degrade it.
You may want to replace your fireplace tube with black iron or steel and see if that makes a difference.
Other things, including chlorine (bleach from cleaning?), pvc (chlorinated vinyl) or boric acid (roach powder) can all tint a flame green or greenish blue. If you, a roommate or other person were using these substances around the fireplace, this may also cause the green flame.
In some cases, such as with vinyl or chlorine, the byproduct of combustion may be phosgene gas, which is quite toxic. So getting this figured out is important.
I might also add that some people actually enjoy having a colored flame. To do this safely, there are products sold, which you can add to your fire to give it colors such as green, blue, magenta and orange. The most popular of these is called Mystical Fire, but there are others as well…

Don’t Eat Hotdogs Cooked Over A Green Flame…..
Went to my neighbors house last night after work and cooked a couple hotdogs over the fire. As I was eating them, he asks “how do you like the green fire?” Now I hadn’t noticed that the fire had some green in it when i was cooking my dogs. He proceeds to tell me that after everyone was done eating, they throw old strands of Christmas Tree lights in the fire. The copper wire burning turns the fire green.
Fast forward to this morning and I feel like a freight train ran over me. Here is a copy and paste from some safety web site…
EFFECTS OF OVEREXPOSURE

usually, start several hours after
exposure; the attack may last 6 to 24 hours.
Complete recovery generally occurs without
intervention within 24 to 48 hours. Metal
Fume Fever is more likely to occur after a
period away from the job (after weekends or
vacations). High levels of exposure may
cause a metallic or sweet taste in the mouth,
dry and irritated throat, thirst, and coughing
at the time of the exposure. Several hours
after exposure, a low–grade fever (seldom
higher than 102 F or 39 C). Then comes
sweating and chills before temperature
returns to normal in 1 to 4 hours.
I have had every one of these symptoms today, so please, do not eat anything cooked over green fire…….
What would cause a gas fire to burn green flames?
The first thing that came to mind was copper compounds.
A quick google search, which I recommend to EVERYONE, came up with the following:
- boric acid (boron compounds) – sold as a disinfectant and roach killer
- borax (boron compounds) – sold as a laundry booster and home cleaner
- copper sulfate [copper(II) compounds] – sold as a root killer and algicide
However, other chemicals will make green flames:
- thallium compounds
- antimony compounds
- barium compounds
- manganese(II) compounds
- molybdenum compounds
- ammonium compounds
- phosphates moistened with sulfuric acid
So why am I using google when you could do it yourself? I really can’t answer that.
Why would the fire burn green?
In ordinary flames, a green color indicates the presence of copper, or a copper compound.
This is sometimes observed when heavily inked paper is burned (like glossy colored magazines or catalogs, for example.) Some inks use copper compounds as pigments.
In pyrotechnic flames (including fireworks), green flames are always made with barium compounds (along with a source of chlorine.)
Many people mistakenly believe that copper compounds are used to make green flames in fireworks. Actually, copper compounds, in conjunction with a source of chlorine, make blue flames in pyrotechnics.

What element burns green in a flame test?
There are many, not surprising given there are about 100 elements stable enough to subject to a flame test but not 100 colours as broadly defined as “green”
Those I can remember off hand include boron. barium, copper, molybdenum (that’s quite a yellowish green), thallium (be very careful doing that one it’s horrid stuff), copper, manganese, some people say phosphorus but I’d call that one turquoise, antimony, vanadium and I’m pretty sure tellurium.
If you want green candle flames to soak the wick in sodium borate solution and let it dry very well. I found that a better color than copper sulfate and I prefer the idea of boron in the atmosphere to copper, but both would be at very low levels.
CauseA green flame, for instance, indicates the presence of copper. As copper heats up, it absorbs energy that’s manifested in the form of a green flame. A pink flame, on the other hand, indicates the presence of lithium chloride. And burning strontium chloride will create a red flame.
