I have compiled a list of sources for the elements that are available to the amateur chemist. Sulfur will be discussed here.
Sulfur is a yellow crystalline substance. It is a brittle flammable nonmetal. It burns to make the noxious gas sulfur dioxide. Sulfur is a relatively common mineral. Sulfuric acid is the most important industrial chemical. Sulfites are used to preserve dried fruits. Sulfur melts to a thin yellow liquid, which when heated creates a thick red liquid. This, when further heated, burns in air or vaporizes in an inert atmosphere. If the red liquid is dropped in water, a rubbery form of sulfur is created.
In element form: Flowers of sulfur (pure sulfur) is available at drug stores. Many chemistry kits have sulfur in them.
In compound form: Epsom salts are made of magnesium sulfate. Sulfuric acid is used in lead-acid batteries. Pyrite is an iron sulfide mineral.
Here is my sample of sulfur. It is from a chemistry kit. It has a very faint odor.
