Description
A synthetic pigment composed of a double salt of phosphoric acid with manganese and ammonium. Manganese violet was first introduced in Germany in 1868 as Nuernberg violet. By 1890 it was commercially available in England from Winsor & Newton. It has a deep rich violet hue but has poor hiding power and has not been widely used. Manganese violet is lightfast and can be used in all techniques except for fresco.
