Discovery of Manganese

The name Manganese is a name from a corrupted latin word magnestism or magnes, which is an allusion to the ore of magnetic properties. Manganese crystals are to be found in nature. Manganese is technically not a mineral, but with laboratory being widely expanded growth within specimens look like a natural stone.
