The blue lava phenomenon occurs thanks to a large amount of pockets of sulfur present in the rocks. Sulfur is a chemical element that when burned emits harmful gases such as sulfur dioxide, and the burning of this element causes the blue color.

So when this sulfur comes in contact with oxygen, it ignites and causes the blue flame that gives the lava the appearance of being that color. In reality, however, the phenomenon is just the surface of molten rock covered in blue flames.
Also, although visible at night, the blue flames always glow on the surface of the lava, making them harder to see in the morning.
Is it possible to use the lake Kawah Ijen?
NO! After all, Lake KawahIjen has very high toxicity and acidity. This is because it contains a lot of hydrochloric acid and sulfuric acid. Its water can cause respiratory problems, skin irritation and, in extreme cases, even death.
