At the Kawah Ijen volcano in Indonesia, bright yellow elemental sulphur is mined, but the valuable sulphur is also flammable and easily catches fire. It burns with a blue flame but also produces choking fumes of sulphur dioxide. Each night a team of workers must brave the harsh conditions and put out the flames to keep the mine active and the sulphur pure.
