These sulfides are produced when things decay without air. Sulfur compounds are chemical compounds containing sulfur ions. Sulfur comes in several forms: oxidation states of -2 (hydrogen sulfide), +4 (sulfur dioxide, sulfites) and +6 (sulfuric acid, sulfates) are most common, although there are other oxidation states.
Sulfur most often occurs as a thin dusty covering on other objects. In this form, the texture of the element is powdery. At other times, sulfur occurs in crystal form. Crystallized sulfur may have a smooth or bumpy texture, depending on its age, impurities and the circumstances surrounding its origin. Sulfur is a brittle crystal, and it has limited commercial applications.
