Raw Umber Greenish 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.

Smalt is a kind of cobalt blue glass or frit, and its use as a pigment dates from the 1600s in the glass-making regions of Saxony. We offer two shades, light and dark, which are determined by the particle size of the pigment; the more finely ground the powder, the paler the colour. Before the introduction of Ultramarine Blue, Smalt was available in a wide variety of grades. It is a very transparent pigment, which is easily overwhelmed in mixtures due to its weak tinting strength. It works best in water based media. When ground in oil, it can become almost invisible in dried oil-paint films because its refractive index is so close to that of linseed oil.

Madder Lake pigment is derived from dye that has been extracted from the root of the madder plant, and attached to alum as a base. It has largely been replaced by synthetic alizarin pigments, but it is still used as an ingredient in some commercially-available paints. It provides a very transparent pigment, with a weak tinting strength, which can be used in all lime-free media, although it is very slow-drying in oil. It is fugitive to sunlight, so paintings containing Madder should be stored appropriately, but it remains one of the most lightfast plant-based pigments. It requires a wetting agent to aid dispersion.

The madder plant was once widely cultivated for the red dye extracted from its roots. Its earliest known use is in ancient Egypt, and there is evidence of its widespread adoption in Europe from the medieval period. Madder Lake, the pigment that is derived from the root, has now largely been replaced by synthetic alizarin pigments, but it is still used as an ingredient in some commercial paints. It provides a very transparent pigment, with a weak tinting strength, which can be used in all lime-free media, although it is very slow-drying in oil. It is fugitive to sunlight, so paintings containing Madder should be stored appropriately, but it remains one of the most lightfast plant-based pigments.

NY13:75640 Stil de Grain is a natural yellow pigment derived from unripe buckthorn berries, which were also once used to produce sap green pigment before the introduction of synthetic alternatives. Stil de Grain may also be known as brown lake, yellow lake, Persian lake, buckthorn lake, Dutch pink, yellow carmine and Italian pink. It has a weak tinting strength, and is very transparent, especially in oil. When mixed with oil, the pigment becomes saturated, darkening considerably in colour and drying very slowly, whereas in a water-based paint it is appears as a warm yellow. It is very fugitive to light, and compatible with all media, except lime. Larger quantities are available by request. Learn More

Cadmium Red is a synthetic organic pigment that has been in use since the 1920s. 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. This shade has been formulated to imitate the bright hue of vermilion.

Phthalo (Mona) Blue is a synthetic organic pigment, Copper Phthalocyanine, that has been in use since the 1930s. It has an extremely high tinting strength and is a staining colour, so cannot successfully be lifted in watercolour. It requires a wetting agent to fully disperse into a medium, and, when used at full strength, a copper sheen is visible in dried paint film. It is transparent, very lightfast, and has a medium-to-slow drying rate in oil.

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 specifically used this name in the late-Middle Ages, as the presence of Cobalt ore in the mines made the extraction of silver very difficult. They were possibly aware of the toxic properties of the mineral 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.

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.

Ultramarine Blue 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. It reacts to alkali, therefore it is not suitable for use in lime-fresco; we do offer a Limeproof Ultramarine Blue for this purpose. 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.

Prussian Blue is a synthetic organic pigment that was discovered by the paint maker Diesbach, apparently by accident, in Germany in the early eighteenth century. For many years, it was used not only as a colour in its own right, but also as a component of the original Hooker's Green. The other ingredient, gamboge, is highly fugitive, which is why many watercolours painted with Hooker's green have taken on a bluish tone with with age.  

It is a very transparent and heavily staining colour. It dries quite quickly in oil, and can therefore wrinkly if applied too quickly. It is suitable for use in oils, watercolour, and egg tempera. However, it shouldn't be used in conjunction with alkali substances, such as Lead White or Calcium Carbonate as it can turn brown, so it isn't suitable for fresco. For the same reason, it isn't used with acrylic resin binders due to their alkaline nature, so most paint manufacturers will replace Prussian Blue with a mixture of Phthalo Blue and black in their acrylic ranges. It requires a wetting agent to fully disperse into a binder.

Genuine Indigo is a natural vegetable pigment derived from the Indigofera Tinctoria plant, which was first imported into Europe from India in the seventeenth century. It replaced woad, which had been grown natively in Europe for its blue dye. The leaves are soaked in water to ferment; upon drying, an oxidised residue forms on the dry leaves, which is removed, washed, boiled in water, and then dried to form cakes of pigment or dye.

Indigo is very transparent, with a good tinting strength. It requires a wetting agent to disperse, and in oil it dries very slowly. It is fugitive to light; this drawback means that it is no longer commonly available in commercial paints. It fell out of general use at the beginning of the seventeenth century, largely replaced by Prussian Blue, and synthetic Indigo was patented in the 1890s. However, it provides a subtle shade of blue that is still desirable in works that are going to be protected from light.

Alizarin Crimson is a synthetic organic pigment that became available in 1868. It requires a wetting agent to disperse, and in oil it also absorbs a lot of liquid and dries very slowly to form a hard, brittle paint film. It is chemically identical to madder-root pigments and should be protected against UV light where possible as it can fade when applied onto a white ground, although it is less fugitive than its natural counterpart. Alizarin Crimson is a very transparent pigment, with a high tinting strength and slightly blue undertone.

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.

A glass slab with wooden cradle for the grinding of pigments.

The friction created between the sand-blasted surfaces of the glass slab and muller facilitates the thorough mixing of pigment and medium, creating a consistent and strong paint body. This slab can be used to manufacture many types of paint including watercolours, egg tempera and oils.

Mulling is of particular importance when making oil paint; simply mixing pigment and oil together using a palette knife will result in an unstable substance with poor plasticity, which contains a large amount of excess oil and unevenly distributed pigment particles. Thorough mulling in a figure-of-eight motion will enable the pigment to be fully combined into the binder, strengthening the resultant paint film.

PLEASE NOTE: The separate glass slabs are in stock but it is a call to order item due to the fact that we cannot guarantee its safe delivery, however well we package it. Please ring us to discuss your delivery options. In combination with the glass frame, delivery is more secure but we still cannot guarantee a delivery without breakage.
