A flame’s color depends on two things: the temperature of the flame and the material being burned. The main color in the flame changes with the temperature. Something is “red hot” from 977 degrees Fahrenheit to 1,830 degrees. Orange flames burn at 2,010 to 2,190 degrees.

Acetylene and pure oxygen burns blue, at over 3,400ºC – the hottest temperature readily achievable with fuel and flame.
Is blue fire real?
In Ethiopia’s Danakil Depression, the sulfur dust in the soil of a hydrothermal vent ignites to form blue flames. Grunewald has also documented the blue glow on the Dallol volcano in the Danakil Depression, in the Afar region of Ethiopia near the borders of Eritrea and Djibouti.
How hot is pink fire?
The color of fire is more dependent on the type of material burning than the temperature. That said, strontium and lithium salts and carbonates burn red-pink, at approximately 500 degrees centigrade.
What gift does a godparent give at baptism?What color does salt burn?
Basic table salt burns yellow. The flames coming off of copper are bluish-green. Potassium burns violet. With all of these salts burning different colors, all teachers have to do is line them up in the order of colors in a rainbow — red, orange, yellow, green, blue, indigo and violet.
Is Gray fire Possible?
Most fires will produce a mixture of black, gray, and nearly white smoke because of the variety of fuels and the variability of air supply.
Does 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.
Does invisible fire exist?
Ethanol fires are nearly invisible and burn incredibly hot. The fire “flashed” almost immediately filling the nearly 1,500 sq. ft. room with invisible flames and creating intensely high heats.
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.
How hot is Dragon fire?
While more than a few Thrones fans have tried to solve the dragon fire conundrum, Reddit user MrBananas posits that, in order to roast hundreds of people and immediately carbonize them into ash, which poor Arya witnesses firsthand, the dragon fire could have reached heights of 10,000 degrees Fahrenheit.

It’s uncommon on Earth, but it does happen. The differences between “hot” and “cold” varieties are fairly plain: When a cold flame ignites, it might only kick out heat hotter than its surroundings by a few tens of degrees Celsius, while a hot flame spikes the temperature by thousands.
What color is pure fire?
Near the logs, where most burning is occurring, the fire is white, the hottest color possible for organic material in general, or yellow. Above the yellow region, the color changes to orange, which is cooler, then red, which is cooler still.

The color of the flames is apart of temperature affected also by the type of fuel used (i.e. the material being burned) as some chemicals present in the material can taint flames by various colors. Blue-violet (purple) flames are one of the hottest visible parts of fire at more than 1400°C (2552°F).
Is red fire possible?
Scientists have learned that red flames correspond to temperatures from 980º F up to 1,800º F. Flames turn orange when the temperature reaches 2,000º F to 2,200º F. When temperatures approach 2,400º F to 2,700º F, flames appear white.

How hot is blue fire?
The color blue indicates a temperature even hotter than white. 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.
