Yellow Ochre is a natural earth pigment that has been in use since prehistoric times. It is derived from iron-rich clay deposits that are present all over the world; our Yellow Ochre comes from the hilly regions around Verona, Italy. As a pigment, it is semi-opaque, extremely lightfast, and stable in all media. It has a medium to slow drying rate in oil, creating a tough, flexible paint film. Yellow Ochre is similar in composition to Raw Sienna, but whereas Yellow Ochre contains a higher proportion of clay, Raw Sienna contains a higher proportion of silica. As a natural material, the exact colour and qualities of the resultant pigments can vary, but generally this compositional difference creates a paler, more opaque Yellow Ochre, and a darker, more transparent Raw Sienna.

Cobalt Green is a synthetic pigment that consists of compounds of cobalt and zinc oxides. It is sometimes referred to as Rinman's Green, after the Swedish chemist who discovered it in the late-18th century. It is a permanent, opaque colour, with a weak tinting strength. It dries quite quickly in oil, requiring a high oil content and  forming a hard, fairly fleixible paint film. Cobalt Green is available in light and dark shades; the colour is determined by the amount of zinc oxide present.

Mars Black is an artificial mineral pigment composed of hydrated ferric oxides. Like other Mars colours, it provides a very opaque, permanent colour, which is stable in all media. It has an average drying time in oil, forming a hard, fairly flexible film, making it more suitable for impasto application than carbon-based black pigments, which tend to be brittle. It also wets more easily than other black pigments, and possesses a warm, brownish undertone.

Toxicity: B

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.

Viridian Green is a synthetic inorganic pigment, similar in composition to Chromium Oxide. However, unlike Chromium Oxide, Viridian contains water molecules within its crystal structure, imparting a greater degree of transparency. Sometimes referred to as Verte Eméraude, Viridian was discovered in France in 1838, patented in 1859, and made available in the UK in 1862. It is stable in all media, and offers excellent lightfastness and good tinting strength. It requires a high oil content, and dries slowly to form a hard, fairly flexible paint film.

Prussian Blue is a synthetic organic pigment that was discovered by the paint maker Diesbach, apparently by accident, in Germany in the early eighteenth century. For many years, it was used not only as a colour in its own right, but also as a component of the original Hooker's Green. The other ingredient, gamboge, is highly fugitive, which is why many watercolours painted with Hooker's green have taken on a bluish tone with with age.  

It is a very transparent and heavily staining colour. It dries quite quickly in oil, and can therefore wrinkly if applied too quickly. It is suitable for use in oils, watercolour, and egg tempera. However, it shouldn't be used in conjunction with alkali substances, such as Lead White or Calcium Carbonate as it can turn brown, so it isn't suitable for fresco. For the same reason, it isn't used with acrylic resin binders due to their alkaline nature, so most paint manufacturers will replace Prussian Blue with a mixture of Phthalo Blue and black in their acrylic ranges. It requires a wetting agent to fully disperse into a binder.

NY13:75640 Stil de Grain is a natural yellow pigment derived from unripe buckthorn berries, which were also once used to produce sap green pigment before the introduction of synthetic alternatives. Stil de Grain may also be known as brown lake, yellow lake, Persian lake, buckthorn lake, Dutch pink, yellow carmine and Italian pink. It has a weak tinting strength, and is very transparent, especially in oil. When mixed with oil, the pigment becomes saturated, darkening considerably in colour and drying very slowly, whereas in a water-based paint it is appears as a warm yellow. It is very fugitive to light, and compatible with all media, except lime. Larger quantities are available by request. Learn More

Isinglass is derived from the dried swim bladders of fish, with Salianski Isinglass being the highest grade available. In the Russian Icon tradition, it commonly provided the glue component in gesso recipes, and was sometimes mixed with pigment to make tempera paints, due to its high binding strength. It can be used to make a pale, clear glue, which is less prone to darkening than other animal glues, and which is particularly flexible, making it a useful material for repairing textiles.

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.

Raw Sienna is a natural earth pigment that dates back to antiquity. Our Raw Sienna comes from areas of Tuscany where the earth has been coloured by iron-rich minerals. It provides a good tinting strength, excellent lightfastness, and a fast to medium drying rate in oil. It is stable in all media but, like umber pigments, can be difficult to disperse in an acrylic binder. It is similar in composition to Yellow Ochre, but whereas Yellow Ochre contains a higher proportion of clay, Raw Sienna contains a higher proportion of silica. As a natural material, the exact colour and qualities of the resultant pigments can vary, but generally this difference creates a paler, more opaque Yellow Ochre, and a darker, more transparent Raw Sienna.

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

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.
