Lapis Lazuli Dark Pigment
Starting at: £12.20
PB29
Lapis Lazuli is a natural mineral pigment, mined in Afghanistan and South America. Different shades of Lapis Lazuli are determined by the intensity of colour of the lazurite vein; we offer the pigment in light and dark. For many centuries it was the most reliable blue pigment available, and became particularly significant during the Medieval and Renaissance periods, when its inclusion in a work of art denoted the wealth and status of the patron, or the holiness of a painting's subject. In commercial paint production it has largely been replaced by the more affordable Ultramarine Blue, although it still has a place on modern palettes due to its unique soft violet tone. It is a transparant pigment, with a low tinting strength.
Larger quantities are available by request.

Lapis Lazuli Middle Pigment
Starting at: £10.20
Lapis Lazuli Middle Pigment. Usage dates from the Middle Ages when it was the only reliable blue pigment. Different intensities of genuine ultramarine are caused by the varying intensities of colour in the original lazurite vein Learn More -

Smalt Dark Pigment
Starting at: £5.30
PB32
Smalt is a kind of cobalt blue glass or frit, and its use as a pigment dates from the 1600s in the glass-making regions of Saxony. We offer two shades, light and dark, which are determined by the particle size of the pigment; the more finely ground the powder, the paler the colour. Before the introduction of Ultramarine Blue, Smalt was available in a wide variety of grades. It is a very transparent pigment, which is easily overwhelmed in mixtures due to its weak tinting strength. It works best in water based media. When ground in oil, it can become almost invisible in dried oil-paint films because its refractive index is so close to that of linseed oil.

Verdigris Pigment
Starting at: £4.90
Verdigris is an artificial pigment that dates from antiquity. Originally, it was produced by exposing copper to vinegar; nowadays acetic acid is used. It is acidic, so can contribute to the deterioration of paper supports. For this reason, it is more suited to oil or tempera painting than it is to watercolour. In tempera painting, it should be bound in animal glue or isinglass glue rather than egg york. When used in oil painting it should be held in a resin oil or balsam such as Venice Turpentine, as it can turn brown when ground directly into linseed oil. It is a fast-drying, transparent pigment, with a visible crystalline structure.

Egyptian Blue Pigment

Blue Verditer Pigment
Starting at: £4.90
Blue Verditer, sometimes referred to as Bremen Blue, is a synthetic form of Azurite, or copper-calcium carbonate. It has a weak tinting strength and is sligtly transparent. It works best in water-based binders, as the acidity of linseed oil can cause discolouration.

Realgar Pigment
Starting at: £12.75
Realgar, like Orpiment, is sulphide of arsenic, and these two substances are often found in close proximity to each other in nature. Realgar exists in small deposits throughout the world and has been used for its colour since ancient times, although its extreme toxicity means that it has been superseded by cadmiums in modern painting. It is an opaque pigment with poor tinting strength.

Azurite Pigment
Starting at: £11.80
PB30
Azurite is a naturally occuring copper carbonate, with a long history within European and Asian painting. It was mined in northern Europe, so was a less expensive source of blue than Lapis Lazuli, which was imported from Afghanistan. Medieval artists would often use Azurite in underpaintings, before applying layers of Lapis Lazuli during later stages of production.
It is best used in aqueous media, as the acidity of oils can cause it to darken in colour, although this can be somewhat counteracted by protecting the pigment particles with a protein such as egg yolk. It has a very low tinting strength, and the particle size tends to be quite large, to give a darker colour. It is sensitive to damp conditions, and is slightly transparent.

Vermilion Genuine Pigment
Starting at: £15.90
PR106 Vermilion is an artificial pigment based on mercuric sulphide, which occurs naturally as Cinnabar. The synthetic form contains fewer impurities than Cinnabar, and was in use in China as early as the fourth century. It was present in Europe from the ninth century, and was the most widely used red pigment until the introduction of Cadmium Red in the early twentieth century. It has good tinting strength and opacity but, like many red pigments, it dries very slowly in oil media. Larger sizes available on request. Learn More -
Rose Madder Genuine Pigment
Starting at: £15.80
NR9 Rose Madder is an alizarin lake pigment made by precipitating dye extracted from madder root onto an inert base. It has largely been replaced by synthetic alizarin pigments, but it is still used as an ingredient in some commercially-available paints. It provides a very transparent pigment, with a weak tinting strength, which can be used in all lime-free media, although it is very slow-drying in oil. It is fugitive to sunlight, so paintings containing Madder should be stored appropriately, but it remains one of the most lightfast plant-based pigments. It requires a wetting agent to aid dispersion. Larger quantities are available by request Learn More -
Carmine Red Genuine Pigment
Starting at: £9.90
NR4
Carmine has been used as a dye and pigment since antiquity. Originally derived from the kermes insect, it was replaced by cochineal following the discovery of the Americas. It has a good tinting strength and is very transparent, although it is fugitive to light.
