Roberson Cold Pressed Linseed Oil
Starting at: £7.50
Linseed Oil is derived from flax seeds, and appears on our shelves in many guises: Cold Pressed, Refined, Stand Oil, and as a key ingredient in many mediums. It has been appreciated for its drying properties since the Medieval period, and has become the most popular oil used in painting today due to the strong, flexible and glossy film that it creates. Cold Pressed Linseed Oil is ideal for the grinding of pigment to make oil paints. The process of producing Cold Pressed Linseed Oil results in a lower yield, but the resultant oil is of a superior quality to oil that has been extracted by other methods, creating a paint film that is more resistant to embrittlement on aging. Its yellow colour is caused by the high concentration of linolenic acid, the presence of which provides durability to the paint film. The amount of oil that each pigment requires can vary enormously. Alizarin Crimson, for example, requires a high percentage of oil compared to most other colours. We would always recommend mulling the pigment and oil together thoroughly to create a "short" or buttery paste, with evenly dispersed, well-coated pigment particles. This process contributes to the strength and flexibility of the paint film, and prevents the inclusion of excess oil. Origin: USA Learn More -

Roberson Refined Linseed Oil
Starting at: £13.30
Linseed Oil is derived from flax seeds, and appears on our shelves in many guises: Cold Pressed, Refined, Stand Oil, and as a key ingredient in many mediums. It has been appreciated for its drying properties since the Medieval period, and has become the most popular oil used in painting today due to the strong, flexible and glossy film that it creates.
Alkali Refined Linseed Oil has been treated to reduce its acidity, and is a useful ingredient in mediums and varnishes.

Roberson Poppy Oil
Starting at: £10.20
Poppy Oil is a slightly later addition to the artist's cabinet than Linseed Oil and Walnut Oil. It is generally used as a binder for pale colours, where the warmth of Linseed Oil is not desired. It provides a matte finish and dries very slowly, so we would not advise using it in conjunction with slow-drying pigments or in underpaintings. A paint film produced by Poppy Oil is weaker and softer than that created by Linseed Oil. This is because it contains a smaller percentage of linolenic acid than Linseed Oil; this substance imparts both strength and yellowness to an oil.
Although some of these properties can be perceived as drawbacks, paints made with Poppy Oil generally obtain a "short" or buttery texture without the addition of waxes or other additives, which can be an advantage for certain colours that produce poor consistencies in Linseed oil alone. Sometimes, the addition of a small quantity of Poppy Oil when grinding a tricky or "stringy" pigment in Cold Pressed Linseed Oil can introduce some of benefits of Poppy Oil, without transmitting its negative characteristics.
Paints made with Poppy Oil are particularly suited to "alla prima" working methods, where paint is applied spontaneously. When working in successive layers, Poppy Oil would only be appropriate for the final stages of a painting.

Cornelissen Historical Inks, Iron Oak Gall
Starting at: £9.00
Exclusive to Cornelissen, our intense black Iron Oak Gall Ink is inspired by a medieval recipe using oak galls collected in Cambridgeshire. The small, handmade batches are blended to give the required consistency and strength, and are steeped for several weeks and allowed to mature for several more. Lightfast and fully waterproof 5-7 days after application, Oak Gall Ink has been used for centuries by calligraphers and scribes to create illuminated manuscripts and legal documents. When used on animal skins such as vellum, the acids in the Oak Gall Ink react with collagen, effectively ‘etching’ itself into the surface, hence its permanence. As with all products derived from natural ingredients, there may be slight variations in the colour and consistency of the ink due to seasonal changes. Not Suitable for fountain pens.
