The name itself probably found its way into Latin from the language of the Oscans, an ancient people who inhabited the region including Vesuvius, where sulfur deposits are widespread. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. The stable yellow rhombic form converts on heating to monoclinic needles. Is it sulfur or sulphur? ρ-sulfur is unstable, eventually reverting to orthorhombic sulfur (α-sulfur). This form is prepared by treating sodium thiosulfate with cold, concentrated hydrochloric acid, extracting the residue with toluene, and evaporating the solution to give hexagonal crystals.
