This Volcano has Blue Flames - Kawah Ijen Volcano

Indonesia's Kawah Ijen Volcano, on the island of Java, is one of the most unique places in the world. It has a 1 klm wide caldera lake, which is the Largest Acid Lake in the World.

But the lake alone is not what makes this area so unusual.

Theirs an active sulfur vent at the edge of the lake. As the burning gases cool, they deposit sulfur around the lake.

The sulfur from the vent, is a resource for the local economy. Miners break the cooled material into large pieces and carry it away in baskets, to a Sugar Refinery for $5 US a day.

But that still not the most unusual thing about this place.

We have all seen molten lava & red flames coming off lava, but in this place the flames are blue. The molten rock isn't what's blue it's actually combusting gasses that make the glowing blue flames.

Thanks for watching



it all has to do with the chemistry of combustion when a fuel like a sulfur compound mixes with oxygen in high enough temperatures a combustion reaction happens

Heat gets released and new chemicals are formed like sulfur dioxide and the visible part of the fire is the flames which are caused by a bunch of atoms spewing out light energy.

Basically the energy from the combustion reaction boosts the electrons in the fuel atoms to a more energetic state.

When the electrons fall back to their original state they release all that extra energy as a photon of light the wavelengths of those photons determine what the flames color is and in the case of sulfur compounds catching fire it's an eerie blue glow
