Manganese is used in the same disciplines today as it was in prehistoric times. Used in iron and steel production, it was found in iron ores forged by the Spartans. The Egyptians and Romans used manganese compounds to add or remove color from glass. Manganese compounds can color glass an amethyst color and produce the color of the gemstone amethyst. Most of the world’s deposits of manganese are found in South Africa and Ukraine. Manganese also exists in nodules on the ocean floor, however no economical method of harvesting them has been found. Potassium permanganate (KMnO4) is commonly used in laboratories for its oxidizing properties.
