Origin and History
Potter’s pink was invented by an unknown Staffordshire potter in about 1780. Winsor & Newton introduced it as a watercolor paint in the 19th century under the name “pinkcolor.” The Colour Index lists a chrome aluminum stannate pigment as Pigment Red 233 (77301). This pigment is manufactured by BASF (Germany) under the tradename Sicocer F Pink.
SourceRublev Colours Potter’s Pink is based on early forms of the ceramic pigment.
Chrome Tin Pink is produced by calcining, at high temperatures, varied ratios of Calcium (II) Oxide, Tin (IV) Oxide, Silicon (IV) Oxide, and Chromium (III) Oxide creating crystalline tin sphene. It may have either one or both of the modifiers Boric Oxide and/or Lead(II) oxide. (Ref Color Index 4th edition);
Permanence and CompatibilityAlthough unrated by ASTM International, the composition and prior use of potter's pink plausibly put it in the excellent lightfastness category (I). It is compatible with all pigments and in all vehicles.
Oil Absorption and GrindingPotter’s pink absorbs a medium amount of oil (- g oil per 100 g of pigment).
ToxicityPotter's pink is not considered to be toxic, however, care should be used in handling the dry powder pigment to avoid breathing the dust.
