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.

From their website: The Harlem Duroziez drying medium increases the brilliance and transparency of glazes. It enables the build-up of layers over the course of half a day thanks to the rapid drying effect of thin layers. It is completely dry within three days.

Galkyd "G" Gel is produced by Gamblin. They say:

"Galkyd Gel is a stiffer gel compared to Neo Megilp that holds thicker, sharper brushmarks and dries more quickly. Galkyd Gel increases transparency of oil colours and creates impasto."

From the Winsor & Newton website: A pale viscous oil that slows drying while imparting a tough, smooth enamel finish with no brush marks. Increases film durability. Ideal for glazing and fine detail if mixed with solvent.

From the Winsor & Newton website: This new medium slows drying & improves flow. Ideal for blending, glazing, stroke work, antiquing and staining. Improves transparency and depth. Dries to a durable gloss finish.

From the Winsor & Newton website: A quick drying, semi-gloss medium which thickens slowly and extends tube colour retaining crisp textures brush marks without any visible levelling. Speeds drying (touch dry in 1-6 days depending on colour and film thickness). Resists yellowing. Not suitable as a varnish or final coat.

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.

From their website: The slow-drying J.G. Vibert painting medium holds brush marks, creates a painterly satin film and prevents any sinking. It creates a uniform top film and enables artists to rework old colours for long periods of time.

Gamsol is an odourless mineral spirit created by the American company Gamblin. They describe it as "the safest solvent that allows oil painters to utilize all traditional painting techniques without compromise."

Burnt Sienna is a natural earth pigment that has been in use since antiquity. Our Burnt Sienna comes from Tuscany, and is produced by calcining Raw Sienna to temperatures of about 450 degrees Celsius. This process creates a rich warm colour and increases transparency. It also offers a good tinting strength, excellent lightfastness, and a fast to medium drying rate in oil. It is stable in all media but, like umber pigments, may be difficult to disperse in acrylic binders.

Terre Verte, sometimes known as Green Earth, is a natural earth pigment derived from clay coloured by iron silicate. As with other natural pigments, impurities can prevent it from fully dispersing in an acrylic binder, although it is a popular pigment in all other mediums. It has been in use since antiquity, providing excellent lightfastness and great transparency, with a low tinting strength. It requires a high volume of oil, and dries slowly to create a soft, flexible paint film. When calcined, Terre Verte becomes Burnt Green Earth.

Burnt Umber is a natural earth pigment from Italy, composed of iron oxide, manganese, and aluminium silicate. It is a form of Raw Umber that a has undergone a process of calcination, becoming warmer, more transparent and easier to disperse. It has a good tinting strength, and is very lightfast, quick-drying, and stable in all media. In oils it forms a hard, fairly flexible paint film, though it may be difficult to use in acrylic mediums.
