Gum Copal Manila is derived from the resin of a coniferous tree native to the Philippines. It is not to be confused with other copals, which are the product of fossilised plant materials. It can be dissolved in alcohol to make a spirit varnish, to be used as a substitute for shellac, or as a fixative for pastel and charcoal drawings. Please note, that when used as a fixative it may darken the colour of the image. Learn More

The madder plant was once widely cultivated for the red dye extracted from its roots. Its earliest known use is in ancient Egypt, and there is evidence of its widespread adoption in Europe from the medieval period. Madder Lake, the pigment that is derived from the root, has now largely been replaced by synthetic alizarin pigments, but it is still used as an ingredient in some commercial paints.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.

Gamboge is a natural tree resin, generally extracted by tapping of Garcinia trees, available as a powder and in the solid "pipe" form. One of the unique features of Pipe Gamboge is that it does not require a binding agent to be used as a paint. Instead, colour can be lifted with a wet brush, as from a watercolour pan. When used as a water colour, it gives a bright transparent golden yellow colour. It is highly transparent, fugitive to light, with a weak tinting strength. The powder can be dissolved in alcohol to colour resin-based varnishes. Gamboge was used from ancient times to dye the clothes and also to make a transparent yellow varnish for the colouring of wood, metals and leather.

Smalt is a kind of cobalt blue glass or frit, and its use as a pigment dates from the 1600s in the glass-making regions of Saxony. We offer two shades, light and dark, which are determined by the particle size of the pigment; the more finely ground the powder, the paler the colour. Before the introduction of Ultramarine Blue, Smalt was available in a wide variety of grades. It is a very transparent pigment, which is easily overwhelmed in mixtures due to its weak tinting strength. It works best in water based media. When ground in oil, it can become almost invisible in dried oil-paint films because its refractive index is so close to that of linseed oil.

** While stocks last ** Blue Verditer, sometimes referred to as Bremen Blue, is a synthetic form of Azurite, or copper-calcium carbonate. It has a weak tinting strength and is sligtly transparent. It works best in water-based binders, as the acidity of linseed oil can cause discolouration.

Carmine has been used as a dye and pigment since antiquity. Originally derived from the kermes insect, it was replaced by cochineal following the discovery of the Americas. It has a good tinting strength and is very transparent, although it is fugitive to light.

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

Egyptian Blue is stable in all media, highly transparent, with a weak tinting strength. A synthetically produced calcium copper silicate, it is considered to be the earliest artificial pigment, dating from antiquity and widely used in ancient Egypt. Larger sizes available on request Learn More

Madder Lake pigment is derived from dye that has been extracted from the root of the madder plant, and attached to alum as a 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.

Damar is a pale, almost colourless tree resin, which is soluble in turpentine, but not in alcohol or mineral spirits. It can be used as a varnish or as a glossy painting medium in conjunction with vegetable oils, and is generally preferable to other resin-based varnishes, such as mastic varnish, as it retains its colourless appearance for a longer period of time. In encaustic painting, the inclusion of damar resin imparts toughness and gloss to the paint surface. Learn More

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.

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.

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.

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
