Button Shellac
Starting at: £8.40
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 -
Indigo Blue Genuine Pigment
Starting at: £8.00
NB1
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.

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.

Cadmium Red Deep Pigment
Starting at: £15.00
PR108
Cadmium Red Deep is a synthetic organic pigment, which has been in use since the 1920s, effectively replacing vermilion. 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.
Larger quantities are available by request.

Please note, that when used as a fixative it may darken the colour of the image. Learn More -
Cerulean Blue Pigment
Starting at: £14.50
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.

Caput Mortuum Pigment
Starting at: £4.50
Caput Mortuum is a transparent, lightfast pigment that is stable in all media. Colours described as Caput Mortuum can vary greatly; our pigment is a soft purple-brown, made from a mixture of natural iron oxides.

Raw Umber Pigment
Starting at: £4.00
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.

Ivory Black Pigment
Starting at: £4.50
Ivory Black is a natural pigment of impure carbon, derived from charred animal bones. It is semi-transparent, very lightfast, and offers good tinting strength. It is a particularly slow-drying pigment, which forms a soft, rather brittle paint film in oil.
Compared to other blacks, such as Vine Black, Ivory Black possesses warmer, brownish undertones. It should not be used at full-strength in an underpainting, as subsequent layers are likely to crack. Otherwise, it is a very useful all-purpose black for many types of paint, excluding mortar, fresco or cement.

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

Mixing Slab
Starting at: £24.00
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.

Gum Sandarac
Starting at: £8.60
Gum Sandarac, derived from a coniferous tree, is available in powdered or lump form. It can be dissolved in alcohol to create a varnish that is suitable as an isolating layer in oil painting and as a traditional top coat for egg tempera. It forms a brittle layer, so is only suitable for use on a rigid support. Another application is as a surface preparation for calligraphy; the ground gum can be dusted across a piece of prepared vellum or paper to create a resist, which shrinks ink strokes slightly, making them appear finer, with crisp edges.
