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.

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

Gypsum

Starting at: £5.70

Gypsum is powdered Calcium Sulphate, a traditional ingredient in gesso grounds used in southern Europe. One of the advantages of preparing your painting surface with gypsum is that it allows for a particularly even absorption of the paint film. It can also be added to acrylic primers to increase absorbency or add tooth to a surface. 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.
