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.

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.

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

Gamboge is a natural tree resin, available as a powder and in the solid "pipe" form. It is highly transparent, fugitive to light, with a weak tinting strength. The powder can be dissolved in alcohol to colour resin-based varnishes. In its solid form, Pipe Gamboge 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.

Flake White Pigment, sometimes referred to as Lead White or Cremnitz White, is an artificial mineral pigment, lead carbonate. It is no longer available as a paint, due to its extreme toxicity. For this reason, great care must be taken when handling the dry pigment.

It is not usuable in water-based media, but works well in oils. It creates a flexible paint film that dries quickly. Although opaque, small quantities do not dominate mixtures, and can help slow-drying pigments to dry. For this reason, it has been a popular mixing white historically; in fact, until the mid-19th century, Flake White was the only white pigment available to artists. Although varnishing is generally considered optional for oil paintings, it is recommended for works containing Flake White, as contact with sulphur in the atmosphere can cause it to blacken. It creates a warm white, which can yellow over time when mixed with linseed oil.

Toxicity: D

Permitted uses: Restoration of art works and protected buildings when alternatives unsuitable.
