The dominant shade in a flame changes with temperature. The picture of the fireplace fire is a good example of this variation. Close to the logs, where many burning is occurring, the fire is white, the hottest color feasible for organic product in general, or yellow. Over the yellow region, the color transforms to orange, which is cooler, then red, i beg your pardon is cooler still. Over the red region, combustion no longer occurs, and the uncombusted carbon particles room visible as black smoke.

You are watching: Is blue fire hotter than white fire

According to the info above (source: Wikipedia) the difference in between red-hot and also white-hot is around 1000 degrees. However what about blue-hot?

Anytime you see blue in a fire it is hotter 보다 white. The variety is between 2,600 and also 3,000 levels Fahrenheit and its the many oxygen-rich kind of flame. A bunsen burner is a good example:

Bunsen burner flames:

1) air hole closed

2) air feet slightly open

3) waiting hole half open

4) air hole almost completely open (this is the roaring blue flame).

Bunsen burners use a mixture of gases. Gas burns hotter than organic materials such as wood and straw. Natural gas cooktop flames room blue. Propane flames space blue with yellow tips. The sexty fires room from oxyacetylene torches (about 3000 degrees Centigrade) that combine oxygen and gas to develop pinpoint blue flames.

Color also tells us around the temperature of a candle flame. The inner core of the candle flame is irradiate blue, through a temperature of around 1800 K (1500 °C). The is the hottest component of the flame. The color inside the flame becomes yellow, orange, and finally red. The additional you obtain from the facility of the flame, the reduced the temperature will be. The brightest red part is about 1070 K (800 °C).

The round blue fire is a photograph of a candle burning experiment in the International an are Station. Candle flames on planet have several various temperatures within the flame because of the variations resulted in by convection flows. In the zero gravity of the room station the flame burns rounder, slower, hot and much more blue.

Our traditional associations because that color and temperature tell united state that red is hot and blue is cold. How difficult is it to think that blue together a warm color?

Traditional color theory says that warm colors advance and cool colour recede. In my experience, this is only true as soon as the colors room the same saturation. If you have actually a pure red and also a pure blue – the red advances. If you have actually a brick red and a bright turquoise blue – the blue advances. Greater saturation trumps warmth every time.
