    With its dusky pink tone Potters Pink is an unusual pigment. There is a brighter and a darker variant. Both resemble
    ultramarine red, somewhat warmer and more broken in tone.
    Many modern mineral colors belong to this big group of mixed metallic oxides. This one is its first representative,
    invented already in the middle of the 19th century.
    Potassium-di-chromate, tin iv-oxide, lime and quartz are measured, thoroughly mixed and burned afterwards. The final
    steps are somewhat laborious: thorough washing and careful grinding of the pink chrome tin oxide with its sphene
    and/or titanite structure.
    After careful washing the pigment is innocuous. The grains are quite hard, due to its quartz content. This can even be
    noticed when it is ground very finely.
    The opacity is moderate, better in aqueous techniques; it is less suitable for glazing. This pigment is hard to find both in
    modern technical literature and in color assortments. One cause the relatively high price, due to the complex
    preparation, and the other is the fact, that today this color is only burned in small loads. Around the middle of the 19th
    century however it seemed to have been used more frequently. The up to then only pink color, the inconsistent madder
    pink, could well be replaced completely by this new light-fast mineral color, beside possible mixtures of white with
    dark fiery ferric oxides. In German this color is called “Nelkenfarbe”, carnation color, because it was well suitable for
    flower still lives. But the most important use of this oxide pigment is ceramic techniques, where it frequently is used as
    sub glaze.
    Apart from the use by restorers carnation color can also be quite interesting for artists. Used by itself the colour is not
    very interesting. More interesting is it e.g. in oil/tempera mixing techniques. You can paint a ground with carnation
    Tempera, and then glaze with transparent organic dark red tones. A glazing with violet -, blue or warm tones can
    produce delightful effects. In each case the Pink color should be very well mixed, which is important particularly with
    the preparation of oil color. You may also consider first to grind the powder with water and/or turpentine oil as finely
    as possible before the actual mixing of the paint. This increases the scope of uses.
    The colour corresponds to the rose-red tone of a bright madder lacquer. Potters Pink was originally a solid ceramic
    material. In addition it was used for porcelain painting and as printing ink. In water color painting of England in the
    18th to 19th Century it was the only light-fast pink.
    It is made in a complex high temperature solid reaction of tin oxide, alumina and chromium oxide in presence of chalk
    or marble flour. After the reaction the product must be washed carefully to remove the surplus of chromium salts.
    Changing the proportion from tin oxide to chromium oxide leads to small nuances in the colouring. It is absolutely
    stable in any kind of painting medium.
