Source

Rublev 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 Compatibility

Although 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 Grinding

Potter’s pink absorbs a medium amount of oil (- g oil per 100 g of pigment).

Toxicity

Potter's pink is not considered to be toxic, however, care should be used in handling the dry powder pigment to avoid breathing the dust.
