PB33

Manganese Blue is an articficial mineral pigment, that is prepared by heating sodium sulphate, potassium permanganate and barium nitrate to 750-800 degrees Celcius. It has been produed as a pigment and as a colourant for cement since the 1930s, and is notable for its quick drying time in oils, its high transparency, and its bright, slightly greenish colour. Its weak tinting strength can cause it to be overwhelmed in mixtures, and it has a tendency to granulate as a watercolour. It is no longer used in commercial paints, but many manufacturers offer a Manganese Blue Hue, which is typically based upon Phthalocyanine Blue.   

Production of this pigment has now ceased, due to environmental and health concerns, therefore it is only available while stocks last.
