Vine Black Pigment
Starting at: £4.70
PBk8
Vine Black is derived from charred vines, forming an organic pigment of pure carbon. It has been in use since antiquity, providing a cold black with bluish undertones, which creates a blue-grey when mixed with white. It is a very lightfast, slow-drying colour with a medium tinting strength. It requires a wetting agent to disperse properly, and is not suitable for use in fresco, mortar or cement, as the water-soluble impurities within the pigment can create efflorescence.

Alumina Hydrate Light
Starting at: £8.30
Alumina Hydrate is an inert pigment with highly absorbent properties, which can be ground into oil paint as an almost colourless extender. It is often used as an additive in commercial oil paints, particularly in conjunction with transparent or lake pigments, as it provides stability and a homogenous consistency without effecting colour or gloss, although it may effect the pigment strength. When combined with linseed oil, it produces an almost transparent painting medium for extending oil colours. Sometimes referred to as Lake Base. Learn More -
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.

Madder Lake Genuine Pigment
Starting at: £10.20
NR9
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 It has largely been replaced by synthetic alizarin pigments, but it is still used as an ingredient in some commercially-available paints.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.

Colophony
Starting at: £7.30
Colophony is a by-product of the distillation of turpentine. It is soluble in most solvents, but considered an adulterant in varnishes and paints, as it forms a weak surface that is prone to darkening and cracking. It is, however, a key ingredient in wax-based etching grounds, imparting hardness, and can be used in powdered form (rosin) to make aquatints. Learn More -
Manganese Violet Pigment

Orange Shellac
Starting at: £8.00
Shellac is a natural resin that is deposited by the female lac insect on the branches of trees in India and Thailand. It is soluble with alcohol, but not with mineral spirits or turpentine. It forms a tough yet flexible film, with many applications. It is suitable as a top coat for gilding when applied thinly, a sealant for porous surfaces, an isolating layer for tempera paintings, a base for pigmented inks, a protective layer for collograph plates, and a warm varnish for wooden floors and furniture. As it is prone to darkening with age, it is not recommended as a varnish for oils, and its solubility can reduce over time. There are various grades of shellac. When mixed with alcohol, it may initially form a cloudy mixture, due to traces of wax in the shellac, but this should become clear once it has dried. The highest grades of shellac are Clear Dewaxed Shellac, which has been de-coloured using the carbon filtering method, Lemon Shellac, and Orange Shellac, which are pale in colour. Button Shellac is less refined and therefore produces a reddish varnish. It was, in fact, widely used as a red dye before synthetic dyes became available. Learn More -
Cobalt Green Light Pigment
Starting at: £8.70
PG19
Cobalt Green is a synthetic pigment that consists of compounds of cobalt and zinc oxides. It is sometimes referred to as Rinman's Green, after the Swedish chemist who discovered it in the late-18th century. It is a permanent, opaque colour, with a weak tinting strength. It dries quite quickly in oil, requiring a high oil content and forming a hard, fairly fleixible paint film. Cobalt Green is available in light and dark shades; the colour is determined by the amount of zinc oxide present.
Toxicity: B

Madder Root Pieces
Starting at: £27.80
NR9
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.

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.

Flake White Pigment
Starting at: £18.75
Call to Order
PW1
Flake White Pigment, sometimes referred to as Lead White or Cremnitz White, is an artificial mineral pigment, lead carbonate. It is no longer available as a paint, due to its extreme toxicity. For this reason, great care must be taken when handling the dry pigment.
It is not usuable in water-based media, but works well in oils. It creates a flexible paint film that dries quickly. Although opaque, small quantities do not dominate mixtures, and can help slow-drying pigments to dry. For this reason, it has been a popular mixing white historically; in fact, until the mid-19th century, Flake White was the only white pigment available to artists. Although varnishing is generally considered optional for oil paintings, it is recommended for works containing Flake White, as contact with sulphur in the atmosphere can cause it to blacken. It creates a warm white, which can yellow over time when mixed with linseed oil.
Toxicity: D
Permitted uses: Restoration of art works and protected buildings when alternatives unsuitable.

Wild Weld Pigment
£22.00Call to Order
This lake pigment is made from the seeds, leaves and stem of the weld plant (Reseda Luteola) and for a natural dye based pigment is an incredibly lightfast warm yellow. Weld was used extensively throughout the 1700s -1800s to dye textiles and when mixed with verdigris the resulting grassy shade is known as the historical colour ‘Lincoln’s green’. Weld is a rare pigment to use as the pigment is not featured in many paint ranges due to its availability. Also many pigment suppliers will not have it as part of their offering. This pigment is made by extracting the soluble dye material from the plants and converting it into insoluble pigment, this is known as the leaking process. It comes in a 20 ml glass bottle with cork and wax seal. Learn More -

Gum Mastic
Starting at: £20.30
Call to Order
Gum Mastic is a tree resin, which dissolves into a clear varnish with alcohol or turpentine, but not with mineral spirits. Mastic varnishes are more prone to blooming and darkening with age than damar-based varnishes, and painting mediums that contain gum mastic can deteriorate in unpredictable ways. For this reason, it is primarily used in restoration, rather than in the production of artwork. Learn More
