Pyrolusite | Mineralogy4Kids

Pyrolusite; Pyrolusite. One of the most common manganese ore minerals, pyrolusite is used in making steel. It is widespread in its occurrence, forming in lacustrine, shallow marine, and bog deposits. It was named in 1827 from the Greek word for "fire" and "to wash" because it was used to remove brown and green tints in the making of glass.

Later, during Ancient Egyptian and Roman eras, manganese compounds added color to glass. Chemical studies of manganese during the 16th through 19th centuries led to the realization that the addition of manganese to iron ore-based steel made it even harder. In today’s world, manganese is often used for cathodic shielding in the battery industry.
