Clear Dewaxed Shellac
Starting at: £9.20
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 -

Starting at: £18.00
Venice Trupentine is a thick, resinous liquid extracted from the Larix decidua, a larch tree native to Austria. It can impart luminosity, brilliance and gloss when used in mediums and varnishes, and as such it was highly valued during the Golden Age of painting in Venice. It is a slow-drying balsam, which can be diluted with turpentine or placed in a bath of warm water to aid flow.

The powder can be dissolved in alcohol to colour resin-based varnishes.
Pipe Gamboge is available while stocks last. Larger quantities are available by request.

Casein Lactic
Starting at: £18.30
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 Mastic
Starting at: £20.30
Gum Mastic is a tree resin, which dissolves into a clear varnish with alcohol or turpentine, but not with mineral spirits. Mastic varnishes are more prone to blooming and darkening with age than damar-based varnishes, and painting mediums that contain gum mastic can deteriorate in unpredictable ways. For this reason, it is primarily used in restoration, rather than in the production of artwork. Learn More -

Gum Damar
Starting at: £7.50
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 -

Roberson Linseed Stand Oil
Starting at: £9.40
Linseed Oil is derived from flax seeds, and appears on our shelves in many guises: Cold Pressed, Refined, Stand Oil, and as a key ingredient in many mediums. It has been appreciated for its drying properties since the Medieval period, and has become the most popular oil used in painting today due to the strong, flexible and glossy film that it creates.
Stand Oil is paler and more viscous than other Linseed Oils, having been heated and kept at temperature to provoke a molecular change. It is not suitable for grinding colours, but it is a very versatile ingredient that can be thinned with turpentine to create a glazing medium or be included in a varnish. Stand Oil is notable for its ability to smooth out brush strokes to create an enamel-like surface.
