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.

PR106

Cinnabar, composed of mercuric sulphide, is a mineral pigment found in crusts or veins in sites of volcanic activity. It has good tinting strength and opacity but, like many red pigments, it dries very slowly in oil media. Due to its high toxicity, it is no longer an ingredient in commercial paints, but is a prominent colour in historical palettes.

Generally, Cinnabar refers to the natural mineral, while Vermilion refers to the synthetic pigment. Cinnabar has been mined since at least the tenth millennium BC, and used as a painting material, gemstone, and ritual object by many cultures around the globe.

Parchment Clippings, usually waste goatskin vellum, were utilised throughout the Middle Ages to make an animal hide glue. This continued to be commonly used as a sizing for canvas before rabbit skin glue came to prominence in the nineteenth century. Parchment glue is comparable to isinglass glue, as it also produces a very pale, almost transparent glue with a degree of flexibility. Our parchment clippings are a mixture of vellum scraps, and may include goatskin, calfskin and sheepskin. Cennino Cennini gives a recipe for gesso using parchment in his treatise about painting; please see below for our recipe. Learn More

Carnauba Wax is the hardest wax commonly used in the production of artists' materials, with a melting point of 83-86°c. It is derived from a tree native to South America, and is available in a natural colour (grey), or a refined colour (pale yellow). Small amounts of carnauba wax are commonly used in both oil painting mediums and encaustic painting, usually in conjunction with beeswax to add toughness, durability and sheen to the paint film. It creates an inflexible surface, so works best on rigid supports such as gesso panels, and it should be noted that it will raise the melting point of encaustic mixtures. It can produce a glossy finish; as such it is used in waxes and polishes for shoes, cars, musical instruments, furniture, and wooden floors, especially when mixed with beeswax and turpentine.

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. Please see the Formulas & Recipes section on our homepage for a recipe to make your own watercolour paints using Gum Arabic (currently under construction). Learn More

Ivory Black is a natural pigment of impure carbon, derived from charred animal bones. It is semi-transparent, very lightfast, and offers good tinting strength. It is a particularly slow-drying pigment, which forms a soft, rather brittle paint film in oil.

Compared to other blacks, such as Vine Black, Ivory Black possesses warmer, brownish undertones. It should not be used at full-strength in an underpainting, as subsequent layers are likely to crack. Otherwise, it is a very useful all-purpose black for many types of paint, excluding mortar, fresco or cement.

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.

PBr7

Raw Umber is a natural earth pigment composed of iron oxide, manganese, and aluminium silicate. It has its roots in the Umbria region of Italy, and was historically a popular colour for underpaintings, as it dries very quickly. It is semi-opaque, very lightfast, and stable in all media but may be difficult to disperse in acrylic. It requires a large amount of liquid when mixed with oil.

Toxicity: B

Paraffin Wax is a by-product of the petro-chemical industry. It has a low melting point of 50-60°c and a brittle texture, making it unsuitable for encaustic painting or as an additive to oil paints, but it can be used to impart softness to lithographic crayons. As a petroleum product, it is more inert than animal or vegetable waxes, and is therefore not saponified (turned into soap) by alkali substances. Learn More

Casein is a protein derived from dried milk, which has been used in painting since ancient times. It can be combined with Ammonium Carbonate to form an emulsion, which acts as a durable, non-resoluble binder for pigments, producing a matte, fast-drying paint, similar in appearance to egg tempera. We use casein as a binder for our L. Cornelissen & Son Pigment Colour Charts, as it is a medium that clearly showcases the characteristics and behaviour of each pigment in its pure form. Casein paints can be applied in thin layers to watercolour paper, but would require a more rigid support, such as a gesso panel, to be applied thickly, as the comparative inflexibility of the paint layer means that it can be prone to cracking. Subsequent layers of paint should be more diluted to aid adhesion, and impasto effects are not recommended. It is possible to varnish casein paintings using an acrylic or damar varnish to obtain a glossy surface if desired, although this is not a necessary step. Casein can also be used as an ingredient in gesso, and is a suitable binder for fresco secco techniques.

Some pigments may require a wetting agent in order to fully disperse within the binder, in which case alcohol may be used.

Beeswax is derived from melted honeycomb, and is available in two grades. Bleached Beeswax Pellets are white, having been bleached by the sun, and are an appropriate choice for using with pale colours, although they may revert to yellow over time. Natural Beeswax Pellets are yellow in colour, and offer a more flexible structure with a higher resin content. Beeswax has a melting point of 63-66°c, and may turn brown if over-heated. It is the most widely used wax in artists' materials, having a wide range of applications. Please see below for more details.
