The word sulfur comes from the Latin name for this important chemical element. Since much of the earth’s sulfur has been formed from gasses emitted by volcanoes, many mining operations throughout the world are found near extinct volcanoes. Sulfur is used in many manufacturing processes. One of the most notable historically is the production of black powder. Other industries include sulfuric acid, paper making, dyes, insecticides and fungicides.

Deposits of sulfur are found in many places in Europe, Africa, and North and South America. The most famous crystals, well formed and brightly colored, traditionally have come from Sicily. This mineral has been reported from 6 counties in Ohio.
In western Ohio sulfur rarely is found as fine-grained aggregates of small crystals as coatings on gypsum; sometimes it is associated with calcite or celestite in cavities of dolostones.
