Gamboge is a natural tree resin, generally extracted by tapping of Garcinia trees, available as a powder and in the solid "pipe" form. One of the unique features of Pipe Gamboge is that it 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. When used as a water colour, it gives a bright transparent golden yellow colour. It is highly transparent, fugitive to light, with a weak tinting strength. The powder can be dissolved in alcohol to colour resin-based varnishes. Gamboge was used from ancient times to dye the clothes and also to make a transparent yellow varnish for the colouring of wood, metals and leather.

Pipe Gamboge is available while stocks last. Larger quantities are available by request.

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.

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.
