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.

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.

Mars Red 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.

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.

PY43

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.

Ammonium Carbonate is a highly Alkaline substance that reacts with the lactic acid present in casein to form a robust binder for tempera paints. It should only be used in a well-ventilated area, please see below for the Material Safety Data Sheet. Learn More

PBr7

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.

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.

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.

Titanium White, or Titanium Doixide, is an artificial mineral pigment introduced in the 1920s. It is valued for its opacity, good lightfastness, and stability in all media. Its high tinting strength can render it a dominant colour in mixtures. It is very slow drying in oil, and creates a somewhat brittle paint film, though more flexible than Zinc White. Its brightness makes it a popular addition to gesso.

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. Toxicity D.

Cornelissen Glass Mullers are handmade using superior boro silicate laboratory glass, which is 40% harder, more heat resistant, and offers better clarity than soda-lime glass. The base of each muller is ground perfectly flat, and sand-blasted to create a fine tooth to facilitate the grinding of pigments. The tall handle features an ergonomic top, to ease fatigue when grinding large amounts of pigment. Mullers act as flat-bottomed pestles, which are used to grind pigment into a binding medium, suspending it evenly to create a uniform covering of binder around each pigment particle. Using a muller and slab, rather than simply mixing pigment and binder together, will create a more homogenised and stable paint. Use in conjunction with a Cornelissen Glass Slab to make paint efficiently. The sand-blasted texture of the muller and plate helps to push and distribute the pigment throughout the binder quickly. This will mean less grinding, and more painting! Learn More
