You get a blue gas flame with a hydrocarbon gas when you have enough oxygen for complete combustion. When you do have sufficient oxygen, the gas flame appears blue because complete combustion creates enough energy to excite and ionize the gas molecules in the flame.
Why is gas flame blue?
When it begins to burn, propane gas is a different color than other materials that burn, such as wood or oil. When the ratio of fuel to air is correct, there is enough oxygen for complete combustion of propane. The gas molecules in the flame are ionized and the propane flame is blue—as it should be.
What is blue flame mean?
A Blue Flame Indicates Complete Burning of Carbon
If you're using a gas grill or stove, you may discover a blue flame. Propane gas, like firewood, contains carbon compounds. However, it often produces a blue flame instead of an orange or yellow flame because it burns all the carbon.
Why is some fire blue?
The blue in wood flames comes from carbon and hydrogen, which emit in the blue and violet. Copper compounds make green or blue, lithium makes red.
How is blue fire made?
Make blue fire either using a fuel that burns blue or else by adding a metal salt that emits blue light to a flame. You can make blue fire for a chemistry demonstration, Halloween decoration, or “magic” trick. While many fuels burn blue, you need a flame colorant to get a vivid blue flame.

When all flame colors combine, the color is white-blue which is the hottest. Most fires are the result of a chemical reaction between a fuel and oxygen called combustion.
Which gas burns with a blue flame?
In the presence of oxygen including atmospheric concentrations carbon monoxide burns with a blue flame producing carbon dioxide.
What is blue fire called?
The University of Maryland's' scientists have discovered a new type of fire, which they have aptly named “Blue Whirl.” This new fire is small, whirling, transparent, and blue.
Is gas supposed to be blue?
Colors According to the Types of Gasoline

Why is hot fire blue?
Blue flames usually appear at a temperature between 2,600º F and 3,000º F. Blue flames have more oxygen and get hotter because gases burn hotter than organic materials, such as wood. When natural gas is ignited in a stove burner, the gases quickly burn at a very high temperature, yielding mainly blue flames.
Is gas with oil blue?
Re: How to tell if the gas is mixed with oil? It should be coloured if oil is mixed with it, blue, green or red for most oils. If in doubt, dump it in the truck and start over.
How do I make my gas fireplace flame yellow?

What color should a gas flame be?
A healthy, properly burning flame on gas appliances should be blue in color, sometimes with a tiny tip of yellow, with a little light blue triangle at the center. This blue color flame indicates that there is safe, efficient and more complete fuel combustion.
Can fire be purple?
Potassium: Purple
Potassium salts produce a characteristic purple or violet color in a flame. Assuming your burner flame is blue, it may be difficult to see a big color change. Also, the color may be paler than you expect (more lilac).
Is green fire hotter than blue?
While blue represents cooler colors to most, it is the opposite in fires, meaning they are the hottest flames. When all flame colors combine, the color is white-blue which is the hottest.
Is there green fire?
Borax or Boric Acid Green Fire
Adding either chemical to a fire yields a vivid green flame. For best results, mix either borax or boric acid with methanol, a type of alcohol, and ignite the solution. The alcohol burns off, leaving behind a white residue from the boron compound.
Why gas flame is red?
A red or yellow flame is a flame being starved of oxygen, creating incomplete combustion. The flame will be at a much lower temperature and will seem more sooty. The yellow colour comes from the soot particles produced by the flame. Yellow or red flames only burn at around 1,000 degrees C.
Why gas flame is yellow?
Gas burners burn blue if the ratio of fuel to air is correct. A yellow burner flame is a symptom that the burner is not getting enough air for complete combustion of the gas. Correcting this problem involves adjusting the burner's air shutter to admit more air, something that an experienced do-it-yourselfer can do.
Can black fire exist?
This is black fire. When you mix a sodium street light or low-pressure sodium lamp with a flame, you'll see a dark flame thanks to the sodium and some excited electrons. “It's strange to think of a flame as dark because as we know flames give out light, but the sodium is absorbing the light from the lamp.
Is black fire Possible?
Flames emits light and heat, so it seems impossible to make black fire. However, you actually can make black fire by controlling the wavelengths of absorbed and emitted light.
How hot is purple fire?
