INDONESIA. JAVA ISLAND. KAWAH IJEN (GREEN CRATER). ACTIVE EXPLOSIVE VOLCANO. ITS SUMMIT CRATER COUNTAINS A SOLFATARE (TYPIFY OF FUMAROLE REJECTING IMPORTANT QUANTITIES OF SULFUR) FROM WHERE IS EXTRACTED SULFUR. IT SHELTERS AN ACID LAKE RENOWNED TO BE THE MOST ACID OF THE PLANET. THE CRATER IS ALSO KNOWN TO PRODUCE " BLUE VISIBLE FLAMES " AT NIGHT (PRODUCED BY THE SULFUR WHICH IGNITES IN THE CONTACT OF THE AIR). THE SULFUR IS EMITTED IN THE FORM OF VAPORS BEFORE CRYSTALLIZING IN CONCRETIONS. THE ORE OF SULFUR HAS BEEN EXPLOITED FOR SEVERAL DECADES BY VILLAGERS OF THE CALDERA OF THE IJEN. TO OPTIMIZE THE FORMATION OF THIS ORE A SYSTEM OF METALLIC PIPES WAS INSTALLED AT THE EXIT OF THE MAIN MOUTHS. VAPORS ARE COOLED THEN MORE QUICKLY AND THE HIGH CONCENTRATION IN MINERALS ACCELERATES THEIR CRYSTALLIZATION.
