sasso magnesio; prob. corrupted from L. magnes, because of
its resemblance to the magnet. See Magnet, and cf.
An element obtained by reduction of its oxide, as a hard,
grayish white metal, fusible with difficulty, but easily
oxidized. Its ores occur abundantly in nature as the minerals
pyrolusite, manganite, etc. Symbol Mn. Atomic weight 54.8.
Note: An alloy of manganese with iron (called ferromanganese)
is used to increase the density and hardness of steel.
Black oxide of manganese, Manganese dioxide or peroxide,
or Black manganese (Chem.), a heavy black powder MnO2,
occurring native as the mineral pyrolusite, and valuable
as a strong oxidizer; -- called also familiarly
manganese. It colors glass violet, and is used as a
