Mars Violet Pigment
Starting at: £4.50
PR101
Mars Violet is an artificial mineral pigment. Its pigment code, PR101, refers to a wide spectrum of synthetic iron oxide pigments including yellows, oranges, reds, violet-browns and green-browns, which replace many natural earth colours, to provide pigments without impurities and with great opacity. It has a good tinting strength, is lightfast and stable in all media, and has a medium drying time in oil. Although it is similar to Caput Mortuum and Indian Red, it is less transparent than the former and warmer than the latter.

Paraffin Wax
Starting at: £6.60
Paraffin Wax is a by-product of the petro-chemical industry. It has a low melting point of 50-60°c and a brittle texture, making it unsuitable for encaustic painting or as an additive to oil paints, but it can be used to impart softness to lithographic crayons. As a petroleum product, it is more inert than animal or vegetable waxes, and is therefore not saponified (turned into soap) by alkali substances. Learn More -
Parchment Clippings
Starting at: £9.90
Parchment Clippings, usually waste goatskin vellum, were utilised throughout the Middle Ages to make an animal hide glue. This continued to be commonly used as a sizing for canvas before rabbit skin glue came to prominence in the nineteenth century. Parchment glue is comparable to isinglass glue, as it also produces a very pale, almost transparent glue with a degree of flexibility. Our parchment clippings are a mixture of vellum scraps, and may include goatskin, calfskin and sheepskin. Cennino Cennini gives a recipe for gesso using parchment in his treatise about painting; please see below for our recipe. Learn More -

Alizarin Crimson Pigment
Starting at: £4.50
PR83
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.
Toxicity: A/B

Ultramarine PB29 Pigment
Starting at: £9.10
PB29
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.

Carnauba Wax Grey
Starting at: £8.40
Carnauba Wax is the hardest wax commonly used in the production of artists' materials, with a melting point of 83-86°c. It is derived from a tree native to South America, and is available in a natural colour (grey), or a refined colour (pale yellow). Small amounts of carnauba wax are commonly used in both oil painting mediums and encaustic painting, usually in conjunction with beeswax to add toughness, durability and sheen to the paint film. It creates an inflexible surface, so works best on rigid supports such as gesso panels, and it should be noted that it will raise the melting point of encaustic mixtures. It can produce a glossy finish; as such it is used in waxes and polishes for shoes, cars, musical instruments, furniture, and wooden floors, especially when mixed with beeswax and turpentine.

Ultramarine Violet Pigment
Starting at: £6.20
PV15
Ultramarine Violet is a synthetic organic pigment that is produced by heating Ultramarine Blue with Ammonium Chloride, causing the removal of some of the sodium and sulphur and thus a change in colour. It is lightfast and semi-transparent, with a weak tinting strength. In oils, it dries quite slowly, forming a hard, flexible film.

Ultramarine Blue Limewash Pigment

It is a transparent pigment, with a high tinting strength and excellent lightfastness.

Clear Dewaxed Shellac
Starting at: £9.20
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 -
