PB29

Ultramarine Blue Light is an artificial mineral pigment that is produced by heating clay, soda, sulphur and coal to high temperatures. Its name comes from outremer, or over-the-sea, as a reference to the highly-prized Lapis Lazuli pigment which had been imported into Europe from Afghanistan since the Middle Ages. First manufactured in France and Germany in 1828, synthetic Ultramarine provided a brilliant and affordable blue to artists, and it remains one of the most popular blues on artists' palettes today. 

It is a transparent pigment, with a high tinting strength and excellent lightfastness. It reacts to alkali, therefore it is not suitable for use in lime-fresco; we do offer a Limeproof Ultramarine Blue for this purpose. It is stable in all other media, although it can be tricky to grind in oil. Instead of creating a thick, buttery paste, it can remain stringy and deteriorate when stored in a tube. To correct this, many commercial paint manufacturers include additives and waxes in their recipes; if you intend on grinding your own paint, you could try replacing 10-15% of your Linseed Oil with Poppy Oil to improve the consistency. Ultramine Blue provides a slow-drying, fairly hard paint film, which can tend towards brittleness.

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 It has largely been replaced by synthetic alizarin pigments, but it is still used as an ingredient in some commercially-available paints.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

Ultramarine Blue Limewash is an artificial mineral pigment that is produced by heating clay, soda, sulphur and coal to high temperatures.

It is a transparent pigment, with a high tinting strength and excellent lightfastness. Most Ultramarine colours react to alkali and are therefore unsuitable for use in lime-fresco; Limeproof Ultramarine Blue remedies this problem.

Use Cornelissen Mini Glass Mullers 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, more painting! 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.

Shellac is a natural resin that is deposited by the female lac insect on the branches of trees in India and Thailand. It is soluble with alcohol, but not with mineral spirits or turpentine. It forms a tough yet flexible film, with many applications. It is suitable as a top coat for gilding when applied thinly, a sealant for porous surfaces, an isolating layer for tempera paintings, a base for pigmented inks, a protective layer for collograph plates, and a warm varnish for wooden floors and furniture. As it is prone to darkening with age, it is not recommended as a varnish for oils, and its solubility can reduce over time. There are various grades of shellac. When mixed with alcohol, it may initially form a cloudy mixture, due to traces of wax in the shellac, but this should become clear once it has dried. The highest grades of shellac are Clear Dewaxed Shellac, which has been de-coloured using the carbon filtering method, Lemon Shellac, and Orange Shellac, which are pale in colour. Button Shellac is less refined and therefore produces a reddish varnish. It was, in fact, widely used as a red dye before synthetic dyes became available. Learn More
