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.

A glass slab with wooden cradle for the grinding of pigments.

The friction created between the sand-blasted surfaces of the glass slab and muller facilitates the thorough mixing of pigment and medium, creating a consistent and strong paint body. This slab can be used to manufacture many types of paint including watercolours, egg tempera and oils.

Mulling is of particular importance when making oil paint; simply mixing pigment and oil together using a palette knife will result in an unstable substance with poor plasticity, which contains a large amount of excess oil and unevenly distributed pigment particles. Thorough mulling in a figure-of-eight motion will enable the pigment to be fully combined into the binder, strengthening the resultant paint film.

PLEASE NOTE: The separate glass slabs are in stock but it is a call to order item due to the fact that we cannot guarantee its safe delivery, however well we package it. Please ring us to discuss your delivery options. In combination with the glass frame, delivery is more secure but we still cannot guarantee a delivery without breakage.

Potter's Pink is an artificial mineral pigment produced by roasting tin oxide with various other oxides. It was first discovered in the pottery region of Staffordshire in the late-1700s, and in the following century Winsor & Newton introduced Potter's Pink into their watercolour range under the name "pink colour". It went on to become a popular addition to watercolour palettes, offering an opaque, lightfast colour with a weak tinting strength and a medium level of oil absorption.

Phthalo (Mona) Blue is a synthetic organic pigment, Copper Phthalocyanine, that has been in use since the 1930s. It has an extremely high tinting strength and is a staining colour, so cannot successfully be lifted in watercolour. It requires a wetting agent to fully disperse into a medium, and, when used at full strength, a copper sheen is visible in dried paint film. It is transparent, very lightfast, and has a medium-to-slow drying rate in oil.

Manganese Blue is an articficial mineral pigment, that is prepared by heating sodium sulphate, potassium permanganate and barium nitrate to 750-800 degrees Celcius. It has been produed as a pigment and as a colourant for cement since the 1930s, and is notable for its quick drying time in oils, its high transparency, and its bright, slightly greenish colour. Its weak tinting strength can cause it to be overwhelmed in mixtures, and it has a tendency to granulate as a watercolour. It is no longer used in commercial paints, but many manufacturers offer a Manganese Blue Hue, which is typically based upon Phthalocyanine Blue.   

Production of this pigment has now ceased, due to environmental and health concerns, therefore it is only available while stocks last.

Toxicity: C
