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.

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.

PR101

Mars Violet is an artificial mineral pigment. Its pigment code, PR101, refers to a wide spectrum of synthetic iron oxide pigments including yellows, oranges, reds, violet-browns and green-browns, which replace many natural earth colours, to provide pigments without impurities and with great opacity. It has a good tinting strength, is lightfast and stable in all media, and has a medium drying time in oil. Although it is similar to Caput Mortuum and Indian Red, it is less transparent than the former and warmer than the latter.

PR83

Alizarin Crimson is a synthetic organic pigment that became available in 1868. It requires a wetting agent to disperse, and in oil it also absorbs a lot of liquid and dries very slowly to form a hard, brittle paint film. It is chemically identical to madder-root pigments and should be protected against UV light where possible as it can fade when applied onto a white ground, although it is less fugitive than its natural counterpart. Alizarin Crimson is a very transparent pigment, with a high tinting strength and slightly blue undertone.

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.

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.

Precipitate Chalk is fine and white. For use in aqueous mediums as a ground for oil and tempera paintings. Learn More

Gum Sandarac, derived from a coniferous tree, is available in powdered or lump form. It can be dissolved in alcohol to create a varnish that is suitable as an isolating layer in oil painting and as a traditional top coat for egg tempera. It forms a brittle layer, so is only suitable for use on a rigid support. Another application is as a surface preparation for calligraphy; the ground gum can be dusted across a piece of prepared vellum or paper to create a resist, which shrinks ink strokes slightly, making them appear finer, with crisp edges.

Gypsum is powdered Calcium Sulphate, a traditional ingredient in gesso grounds used in southern Europe. One of the advantages of preparing your painting surface with gypsum is that it allows for a particularly even absorption of the paint film. It can also be added to acrylic primers to increase absorbency or add tooth to a surface. Learn More

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.

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.

Gesso di Bologna is a bright white Calcium Sulphate, or gypsum, from Italy, which can be used as a substitute for whiting in the preparation of gesso. It is ground to a particularly fine powder, which makes it a suitable ground for gilding, as the small size of the particles allows for greater compression when burnishing. Learn More

Carrageen Moss is a seaweed that is gathered from the Irish coast, whose natural thickening properties are often exploited by the food industry. It is also used as a size in traditional paper marbling, as it allows colours to float and be manipulated on the surface of the water. Learn More

PY39

Orpiment, also called King's Yellow, is a mineral pigment containing naturally occurring sulphide of arsenic. Its high toxicity, and the prevalence of cadmium pigments, means that it is largely obsolete outside the field of restoration. It works best bound in oil or egg tempera, but it is not reliably permanent. Toxicity D.
