Gamboge Powder
Starting at: £5.20
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.

Verdigris Pigment
Starting at: £4.90
Verdigris is an artificial pigment that dates from antiquity. Originally, it was produced by exposing copper to vinegar; nowadays acetic acid is used. It is acidic, so can contribute to the deterioration of paper supports. For this reason, it is more suited to oil or tempera painting than it is to watercolour. In tempera painting, it should be bound in animal glue or isinglass glue rather than egg york. When used in oil painting it should be held in a resin oil or balsam such as Venice Turpentine, as it can turn brown when ground directly into linseed oil. It is a fast-drying, transparent pigment, with a visible crystalline structure.
