Manganese Blue

An aqueous solution of permanganate of potash yields with baryta-water a

violet mixture, which afterwards becomes colourless, and deposits a blue

precipitate. This retains its colour after washing and drying, but

cannot be recommended as a pigment, being liable to suffer in contact

with organic substances, which deoxidize and decolourize the manganates

and permanganates.
