Manganese Mauve Professional Watercolour is prepared using the mixed phase inorganic metallic phosphate pigment, α and β-ammonium manganese (III) pyrophosphate. The pigment has been selected for its purity, light fastness and reddish violet hue, making it ideal for use in A J Ludlow’s Professional watercolour range.

Historically (from “Pigment Compendium”, page 257), “permanent mauve” was a colour term associated with manganese phosphate, which in Winsor & Newton’s 1892 catalogue, was listed as being made from “Phosphate of Manganese”, but other colourmen list the colour as being derived from other pigments; one describes “permanent mauve” as being a violet toned with “French Ultramarine”, whilst in 1898, Reeves stated that “permanent mauve” is synonymous with “permanent violet” and made with a “combination of alizarin”. Therefore because of this lack of consensus, it would appear that “permanent mauve” was not strictly synonymous with manganese mauve and vice versa.

The ammonium manganese phosphate (C.I. PV16) pigments are very similar in hue to those of cobalt phosphate (C.I. PV14).They also have a higher tinctorial strength and so became more popular as an artists’ pigment.

Attempts to synthesise the redder polymorph, β-ammonium manganese (III) pyrophosphate have always resulted in a solid solution of the 2 crystal phases, α and β.The redness of the manganese pigment used in Manganese Mauve Professional Watercolour is due to the low proportion of α -ammonium manganese (III) pyrophosphate present in the pigment’s crystal matrix.
