Light minerals, such as sulfur are naturally occurring elements or chemical compounds that contain distinct measurable physical and chemical properties. This means sulfur can occur alone in its natural state. Sulfur is known as a native element. This beautiful bright yellow to red-gray mineral is one of the oldest elements there is.

Sulfur is mostly converted to sulfuric acid and is used in fertilizers, fireworks, gunpowder and medicines. Sulfur reacts readily with oxygen and produces a pungent gas called sulfur dioxide.

This piece of sulfur is amazing in color, my favorite piece in the collection.
