  3. Titanium White Pigment

    Titanium White Pigment

    Starting at: £4.00

    Titanium White, or Titanium Doixide, is an artificial mineral pigment introduced in the 1920s. It is valued for its opacity, good lightfastness, and stability in all media. Its high tinting strength can render it a dominant colour in mixtures. It is very slow drying in oil, and creates a somewhat brittle paint film, though more flexible than Zinc White. Its brightness makes it a popular addition to gesso.

  4. Mars Black Pigment

    Mars Black Pigment

    Starting at: £5.70

    PBk11

    Mars Black is an artificial mineral pigment composed of hydrated ferric oxides. Like other Mars colours, it provides a very opaque, permanent colour, which is stable in all media. It has an average drying time in oil, forming a hard, fairly flexible film, making it more suitable for impasto application than carbon-based black pigments, which tend to be brittle. It also wets more easily than other black pigments, and possesses a warm, brownish undertone.

    PBr7

    Raw Umber is a natural earth pigment composed of iron oxide, manganese, and aluminium silicate. It has its roots in the Umbria region of Italy, and was historically a popular colour for underpaintings, as it dries very quickly. It is semi-opaque, very lightfast, and stable in all media but may be difficult to disperse in acrylic. It requires a large amount of liquid when mixed with oil.

  7. Raw Sienna Pigment

    Raw Sienna Pigment

    Starting at: £4.00

    PBr7

    Raw Sienna is a natural earth pigment that dates back to antiquity. Our Raw Sienna comes from areas of Tuscany where the earth has been coloured by iron-rich minerals. It provides a good tinting strength, excellent lightfastness, and a fast to medium drying rate in oil. It is stable in all media but, like umber pigments, can be difficult to disperse in an acrylic binder. It is similar in composition to Yellow Ochre, but whereas Yellow Ochre contains a higher proportion of clay, Raw Sienna contains a higher proportion of silica. As a natural material, the exact colour and qualities of the resultant pigments can vary, but generally this difference creates a paler, more opaque Yellow Ochre, and a darker, more transparent Raw Sienna.

  8. Yellow Ochre Pigment

    Yellow Ochre Pigment

    Starting at: £4.00

    PY43

    Yellow Ochre is a natural earth pigment that has been in use since prehistoric times. It is derived from iron-rich clay deposits that are present all over the world; our Yellow Ochre comes from the hilly regions around Verona, Italy. As a pigment, it is semi-opaque, extremely lightfast, and stable in all media. It has a medium to slow drying rate in oil, creating a tough, flexible paint film. Yellow Ochre is similar in composition to Raw Sienna, but whereas Yellow Ochre contains a higher proportion of clay, Raw Sienna contains a higher proportion of silica. As a natural material, the exact colour and qualities of the resultant pigments can vary, but generally this compositional difference creates a paler, more opaque Yellow Ochre, and a darker, more transparent Raw Sienna.

It is formed by heating cadmium sulphide and selenium, the hue is determined by the level of calcination and proportion of selenium. It is very opaque, and lightfast, with a high tinting strength. It absorbs a small amount of oil, and dries very slowly to form a hard, flexible paint film.

  18. Terre Verte Pigment

    Terre Verte Pigment

    Starting at: £4.00

    Terre Verte, sometimes known as Green Earth, is a natural earth pigment derived from clay coloured by iron silicate.

It has been in use since antiquity, providing excellent lightfastness and great transparency, with a low tinting strength. It requires a high volume of oil, and dries slowly to create a soft, flexible paint film. When calcined, Terre Verte becomes Burnt Green Earth.

  23. Ultramarine Blue Limewash Pigment

    Ultramarine Blue Limewash Pigment

    Starting at: £6.30

    PB29

    Ultramarine Blue Limewash is an artificial mineral pigment that is produced by heating clay, soda, sulphur and coal to high temperatures. Its name comes from outremer, or over-the-sea, as a reference to the highly-prized Lapis Lazuli pigment which had been imported into Europe from Afghanistan since the Middle Ages. First manufactured in France and Germany in 1828, synthetic Ultramarine provided a brilliant and affordable blue to artists, and it remains one of the most popular blues on artists' palettes today.

    It is a transparent pigment, with a high tinting strength and excellent lightfastness. Most Ultramarine colours It react to alkali and are therefore unsuitable for use in lime-fresco; Limeproof Ultramarine Blue remedies this problem. It is stable in all other media, although it can be tricky to grind in oil. Instead of creating a thick, buttery paste, it can remain stringy and deteriorate when stored in a tube. To correct this, many commercial paint manufacturers include additives and waxes in their recipes; if you intend on grinding your own paint, you could try replacing 10-15% of your Linseed Oil with Poppy Oil to improve the consistency. Ultramine Blue provides a slow-drying, fairly hard paint film, which can tend towards brittleness.

  24. Cobalt Blue Pigment

    Cobalt Blue Pigment

    Starting at: £6.30

    PB28

    Cobalt Blue is an artificial mineral pigment, produced by the calcination of cobalt oxide and aluminium oxide. It has been widely used since the early 1800s, following its discovery by the French chemist Thenard at the beginning of the century. The name Cobalt has its roots in the German word Kobold, meaning imp or evil spirit. German miners named it to in the late-Middle Ages, as the presence of cobalt ore in the mines made the extraction of silver more difficult. They were possibly also aware of the toxic properties of the mineral that was frustrating their efforts.

    Cobalt remains a very popular colour today, and is present in most ranges of paints, being a semi-transparent pigment that is stable in all media. As a watercolour, all cobalt pigments tend to granulate. As an oil paint, it requires less oil content than most other pigments, and dries quite quickly. Like Cerulean Blue, some artists may choose to bind it with poppy oil, to avoid any possible colour changes brought about by the yellowish cast of linseed oil and the pigment's weak tinting strength.

  25. Cerulean Blue Pigment

    Cerulean Blue Pigment

    Starting at: £12.60

    PB35

    Cerulean Blue is an artificial mineral pigment that is prepared by heating a mixture of Cobalt Chloride and Potassium Stannate. It was first synthesised in the early nineteenth century, becoming more widely used from 1870, when Rowney introduced Coeruleum Blue into their range. It produces a very bright, clear, and unusually opaque blue, hence its name, which is derived from the Latin for "sky-blue", or perhaps "heaven-blue". It has a very low tinting strength meaning that, although it is stable in all media, some artists may choose to bind it in poppy rather than linseed oil, so that the colour isn't affected by the colour of the binder. It creates a fairly flexible paint film, and is a fast-to-medium drying pigment.
