The sulphur in your match drumhead come from the earth just like any other ore . However , most other mineral are n’t still excavated by hand . From the edges of giant acid pools .
The Ijen volcanos are locate in East Java , Indonesia and offer a quality source for sulfur . Volcanic gaseous state condense as they move up through ceramic tube implant in the volcanic rock . As the gas aplomb , turn to unthaw sulfur and leaks out of the pipes , and hardens into the smelly yellow rock we ’re conversant with . Once it ’s heavily , bunch break apart the sulfur pulley block , load them into baskets , and trundle them up insanely outrageous hills to the rim of the caldera . For reference , the baskets count about 200 pounds and they ’re being carried 980 feet up a 45 to 60 - degree slope all in front of a 600 - foundation - wide-eyed puddle of liquid death ( that is n’t steam in the picture , it ’s a cloud of vitriolic accelerator pedal ) . After reaching the summit , workers then have to descend nearly two miles to the base of the mountain for weighing . On average , a basket of Sulfur will fetch $ 13 and miners will make two trips every mean solar day .
The 200 miners employed at Ijen excavate 14 tons of material a day , just 20 per centum of what the spate produces . [ Wikipedia , Environmental GraffitiviaNeatorama – Image : Matthew Harrigan ]
