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

Liquid lithographic ink and solid (tushe) lithographic ink are highly resistant against acids and can be used to draw on stone, aluminium and zinc plates. Uses a highly dispersed pigment that is compounded from shellac, wax and soap. While the liquid ink is suited for complete covering, the tushe ink is excellent for halftones and transitions. * Please note that the Litho Tusche now comes in a cylindrical shape, rather than the rectangular stick photographed.

Exclusive to Cornelissen, our intense black Iron Oak Gall Ink is inspired by a medieval recipe using oak galls collected in Cambridgeshire. The small, handmade batches are blended to give the required consistency and strength, and are steeped for several weeks and allowed to mature for several more. Lightfast and fully waterproof 5-7 days after application, Oak Gall Ink has been used for centuries by calligraphers and scribes to create illuminated manuscripts and legal documents. When used on animal skins such as vellum, the acids in the Oak Gall Ink react with collagen, effectively ‘etching’ itself into the surface, hence its permanence. As with all products derived from natural ingredients, there may be slight variations in the colour and consistency of the ink due to seasonal changes. Not Suitable for fountain pens.

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

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

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.

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.

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.

Microcrystalline Wax is related to paraffin wax, and is used as a plasticiser in some recipes. It is characterised by the fineness of its crystals in contrast to the larger crystal of paraffin wax. It is generally more viscous, denser, tackier and more elastic than paraffin waxes, and has a higher melting point. Learn More
