About this product range

Professional quality
Pure pigments, gum arabic, and honey

Made in the USA

M. Graham Artists’ Watercolor Tubes are made with thoughtfully selected pigments and Northwest blackberry honey, a nod to early artists who sourced their materials from nature. Custom-milled to preserve the unique qualities of each pigment, the honey’s viscosity enhances color strength and ensures easy dilution, yielding fluid, uniform washes. It also prevents colors from hardening on the palette and in the tube.

Manganese Violet

Pigment code: PV16
Type: inorganic
Chemical name: manganese ammonium pyrophosphate
Chemical formula: (NH4)2Mn2(P2O7)2 - Mn3(PO4)2 * 3H2O or H4O7P2H3NMn
Properties: Manganese Violet is a semi-transparent, bluish-violet pigment with a discrete opacity and low tinting strength. It is the reddest of the violets, and it covers and dries well in oil and tempera. It also performs well in pastel, encaustic, and watercolor. Manganese Violet is not well suited for fresco or acrylic painting. There can be significant differences in color across brands. It shares similar properties with bluish shades of Cobalt Violet.
Permanence: Manganese Violet has excellent permanence and lightfastness, and it is one of the most lightfast, balanced violets in watercolor form.
Toxicity: Manganese Violet is highly toxic if inhaled and moderately toxic if ingested.
History: This pigment was developed in 1868 by E. Leykauf to replace the more expensive Cobalt Violet. It was not offered as an artists’ pigment until 1890.
