Since sulfur melts so easily, artisans can cast it into complex shapes. Historically, woodworkers even used it to create inlays in furniture. These sulfur ornaments sold at Kawah Ijen Mountain in Indonesia were most likely cast as well. Ijen is home to a large sulfur mine and refinery. Photo by Okkisafire. Licensed under CC By-SA 3.0.
