"Blue lava" is an electric-blue fire that burns when sulfur combusts, producing a neon-blue flame. Sulfur burns when it comes into contact with hot air at temperatures above 360 °C (680 °F), which produces the energetic flames. [2] Actual lava is red-orange in color, given its temperature.
The blue fire is ignited sulfuric gas, which emerges from cracks at temperatures up to 600 °C (1,112 °F). The flames can be up to five meters (16 feet) high; some of the gas condenses to liquid and is still ignited. [9] [10] Ijen is the largest blue flame area in the world. Local people refer to it as Api Biru (Blue Fire). [11]
Colored fire is a common pyrotechnic effect used in stage productions, fireworks and by fire performers the world over. Generally, the color of a flame may be red, orange, blue, yellow, or white, and is dominated by blackbody radiation from soot and steam.
This high flame temperature is partially due to the absence of hydrogen in the fuel (dicyanoacetylene is not a hydrocarbon) thus there is no water among the combustion products. Cyanogen, with the formula (CN) 2, produces the second-hottest-known natural flame with a temperature of over 4,525 °C (8,177 °F) when it burns in oxygen. [11] [12]
