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

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.

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

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

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.
