Powdered Rosin
Starting at: £13.90
Rosin is the powdered form of colophony, which is a by-product of the distillation of turpentine. Its primary application is to create tonal areas on metal plates as an aquatint resist. It is also an additive in etching grounds, where it gives a hard surface to the otherwise soft wax. Learn More -

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 -

Casein Lactic
Starting at: £15.95
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
Starting at: £8.60
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.

Madder Root Pieces
Starting at: £27.80
NR9
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.

Zinc White Pigment
Starting at: £4.00
Zinc White, or Zinc Oxide, is an artificial mineral pigment that was first produced in France in the late 18th century. Its use in commercial watercolours as Chinese White pre-dates its inclusion in oil painting. It is a semi-opaque, lightfast pigment, which dries very slowly in oil. Of all white pigments, it produces the most brittle paint film, so is not recommended in large quantities for impasto techniques. However, it is a good addition to a palette which requires a less overwhelming white than Titanium White.
