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 slight 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

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.

Stand Oil is paler and more viscous than other Linseed Oils, having been heated and kept at temperature to provoke a molecular change. It is not suitable for grinding colours, but it is a very versatile ingredient that can be thinned with turpentine to create a glazing medium or be included in a varnish. Stand Oil is notable for its ability to smooth out brush strokes to create an enamel-like surface.

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.

Safflower Oil is light-coloured, making it suitable for grinding pale pigments. It is still sometimes used as a binder for commercially available paints, although due to its very slow drying time it is best reserved for the final layers of a painting. Compared to Linseed oil, Safflower Oil will give a matte finish.

The introduction of Walnut Oil as a pigment binder is contemporaneous with the emergence of Linseed Oil. Their drying properties have been appreciated since the Middle Ages, and throughout history there is evidence of both oils being used alongside each other within the same painting. In fact, until the sixteenth century, it is believed that Walnut Oil was the preferred binding medium among Italian artists. It is made from mature walnut kernals, offering a pale colour and brilliant gloss. For this reason, it is sometimes chosen as a binder for light colours, as it provides a stronger paint film than Poppy Oil, and faster drying times. However, a paint film made from Walnut Oil will tend to be brittle, so it is more suited to a rigid support rather than canvas.
