Natural gum size made to a traditional recipe. Gum Ammoniac is useful for gilding in small areas and, more generally, in detailed gilding. Two applications are needed if gilding on absorbent paper. Raised areas can be developed by using several layers and allowing each layer to dry first. Gum Ammoniac can be reactivated by breathing on the gum surface. Gum Ammoniac comes to us from Asia and is increasingly hard to source. Learn More

Roberson Glass Mullers are handmade using high quality-glass. 

Mullers act as flat-bottomed pestles, which are used to grind pigment into a binding medium, suspending it evenly to create a uniform covering of binder around each pigment particle. Using a muller and slab, rather than simply mixing pigment and binder together, will create a more homogenised and stable paint. 

Roberson Glass Mullers are handmade using superior boro silicate laboratory glass, which is 40% harder, more heat resistant, and offers better clarity than soda-lime glass. The base of each muller is ground perfectly flat, and sand-blasted to create a fine tooth to facilitate the grinding of pigments.

Use in conjunction with a Cornelissen Glass Slab to make paint efficiently. The sand-blasted texture of the muller and plate helps to push and distribute the pigment throughout the binder quickly. This will mean less grinding, and more painting! 

NOTE: Sizes may vary slightly as these are handmade products.

Copaiba Balsam comes from the South American tree Copaifera landsdorfii. Its primary function is to improve the appearance of paint layers that may have become dull, brittle or sunken upon drying. It is a viscous liquid that may be diluted with turpentine, but which should not be used in painting mediums.

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.

Unlike other commercially available oil paints, Roberson Artists' Oil Colours do not contain any fillers, extenders or stabilisers. Each paint consists solely of high-quality pigment that has been ground into cold pressed linseed oil, resulting in a highly pigmented paint. This strength of colour presents the possibility of greater economy of use and a less homogenised texture between each tube, instead allowing the unique qualities of each individual pigment to reveal themselves. By limiting our range to 59 shades, we dispense with colours that can be easily mixed, creating a focussed palette of intense, lightfast paints that offer limitless combinations.

Available in 40ml and 225ml tubes

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.

5 Litre containers are not available in the shop, but only as a special order through the website or over the telephone.

The Liquid Metal range does not tarnish and does not need to be varnished. All colours are intermixable and wash up with water. The Liquid Metal range does not tarnish and does not need to be varnished. All colours are intermixable and wash up with water. Coverage is approximately 7 square metres per litre. Two coats are required for most applications but if applied to walls or ceilings with a roller or a brush then three or four coats are recommended. Because of the highly reflective nature of the metallic paint when applying with a roller to a large area apply the paint evenly in long vertical strokes, finishing off the surface by rolling or brushing in one direction, i.e ceiling to floor. This will help to minimise overlapping and create a smooth and even finish. We recommend the use of a professional quality foam roller in order to achieve the best possible finish. When applying with a roller to a large area, apply the paint evenly in long vertical strokes. Finish off the surface by rolling one direction, i.e. ceiling to floor. This will help minimise overlapping and create a smooth, even finish. These paints can also be sprayed and this will produce the best and most consistent finish. To spray Liquid Metal Acrylics, you will need to use HVLP spray equipment with a 1.6mm or 1.8mm nozzle. To ensure proper flow, paint can be thinned with 25-30% water. 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. 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

Venice Trupentine is a thick, resinous liquid extracted from the Larix decidua, a larch tree native to Austria. It can impart luminosity, brilliance and gloss when used in mediums and varnishes, and as such it was highly valued during the Golden Age of painting in Venice. It is a slow-drying balsam, which can be diluted with turpentine or placed in a bath of warm water to aid flow.
