Roberson Artists' Oil Colour 225 ml
Starting at: £29.60
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

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 Glass Mullers
Starting at: £42.70
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.
