Cobalt Blue Pigment
Starting at: £6.30
PB28
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.

Mixing Slab
Starting at: £19.95
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 Pigment
Starting at: £49.50
PB33
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.

Zinc White Pigment
Starting at: £4.00
Zinc White, or Zinc Oxide, is an artificial mineral pigment that was first produced in France in the late 18th century. Its use in commercial watercolours as Chinese White pre-dates its inclusion in oil painting. It is a semi-opaque, lightfast pigment, which dries very slowly in oil. Of all white pigments, it produces the most brittle paint film, so is not recommended in large quantities for impasto techniques. However, it is a good addition to a palette which requires a less overwhelming white than Titanium White.
