Shell gold, so named because it was historically made and stored in a shallow shell such as a mussel shell, consists of finely powdered genuine gold mixed with a variety of gums. It is mixed with a bit of water and applied in the same way as watercolour. After drying for an hour or so, it can be burnished to a soft, beautiful lustre using an agate stone burnishing tool.
Our Shell gold is used by calligraphers, framers, restorers, iconographers and watercolour artists.
In recent years our colour range of genuine gold has been extended and genuine Lapis Lazuli and genuine Malachite have also been added. Learn More

Cobalt Blue is an artificial mineral pigment, produced by the calcination of cobalt oxide and aluminium oxide. It has been widely used since the early 1800s, following its discovery by the French chemist Thenard at the beginning of the century. The name Cobalt has its roots in the German word Kobold, meaning imp or evil spirit. German miners named it to in the late-Middle Ages, as the presence of cobalt ore in the mines made the extraction of silver more difficult. They were possibly also aware of the toxic properties of the mineral that was frustrating their efforts.

Cobalt remains a very popular colour today, and is present in most ranges of paints, being a semi-transparent pigment that is stable in all media. As a watercolour, all cobalt pigments tend to granulate. As an oil paint, it requires less oil content than most other pigments, and dries quite quickly. Like Cerulean Blue, some artists may choose to bind it with poppy oil, to avoid any possible colour changes brought about by the yellowish cast of linseed oil and the pigment's weak tinting strength.

Cornelissen Series 1855 Sable Brush Size 12. The box contain 1 x Artists' Quality Kolinsky Sable watercolour Brush and a brush soap. Learn More

A glass slab with wooden cradle for the grinding of pigments.

The friction created between the sand-blasted surfaces of the glass slab and muller facilitates the thorough mixing of pigment and medium, creating a consistent and strong paint body. This slab can be used to manufacture many types of paint including watercolours, egg tempera and oils.

Mulling is of particular importance when making oil paint; simply mixing pigment and oil together using a palette knife will result in an unstable substance with poor plasticity, which contains a large amount of excess oil and unevenly distributed pigment particles. Thorough mulling in a figure-of-eight motion will enable the pigment to be fully combined into the binder, strengthening the resultant paint film.

Manganese Blue is an articficial mineral pigment, that is prepared by heating sodium sulphate, potassium permanganate and barium nitrate to 750-800 degrees Celcius. It has been produed as a pigment and as a colourant for cement since the 1930s, and is notable for its quick drying time in oils, its high transparency, and its bright, slightly greenish colour. Its weak tinting strength can cause it to be overwhelmed in mixtures, and it has a tendency to granulate as a watercolour. It is no longer used in commercial paints, but many manufacturers offer a Manganese Blue Hue, which is typically based upon Phthalocyanine Blue.   

Production of this pigment has now ceased, due to environmental and health concerns, therefore it is only available while stocks last.

Gum Arabic is a resoluble binding agent, commonly used in the preparation of watercolours, but also useful as an adhesive, a size, and in the production of soft pastels. It is a natural product, harvested from the Acacia tree between October and May. The highest grade of Gum Arabic comes from the Kordofan region of Sudan. It is exceptionally pale and pure and therefore particularly suited to watercolour painting, while Nigerian Gum Arabic (while stocks last) is better suited to stone lithography and other printmaking techniques.

Phthalo (Mona) Blue is a synthetic organic pigment, Copper Phthalocyanine, that has been in use since the 1930s. It has an extremely high tinting strength and is a staining colour, so cannot successfully be lifted in watercolour. It requires a wetting agent to fully disperse into a medium, and, when used at full strength, a copper sheen is visible in dried paint film. It is transparent, very lightfast, and has a medium-to-slow drying rate in oil.
