The oil uses many single pigments for brilliance and clean colour mixing to bring out the individual colour characteristics, from opacity to transparency. The wOil formulation does not contain water.

The linseed oil and safflower oil vehicles have been modified to allow the colour to mix with water, creating a stable emulsion while retaining the working characteristics of traditional oil colour. The wOil colours and wOil mediums and varnishes allow you to achieve all traditional oil painting techniques.

Key: Opacity - (T) Transparent, (ST) Semi-Transparent, (SO) Semi-Opaque, (O) Opaque.
ASTM-LF = Lightfastness ASTM D-4302 - (l) Excellent, (ll) Very Good, (lll) Good, (NR) Not Rated.

wOil is ideal for the following artists:

• Oil painters who are sensitive or want to avoid exposure to solvents such as mineral spirits or turpentine.
• Students and teachers in schools and colleges, where traditional oil colour is prohibited because solvents with health cautions are needed.
• Artists who work in a small home environment and wish to reduce the odour of traditional oil painting techniques.
• Traveling artists can transport all wOil products 9 Colour and Mediums) on airplanes (subject to individual airline regulation).
• Conforms to ASTM D-4236

The wOil range has been formulated using many single pigments for brilliance of colour and clean colour mixing. The most suitable oils and dispersion methods have been selected to bring out the individual colour characteristics, from opacity to transparency. There is no water in the wOil formulation.

The linseed oil and safflower oil vehicles have been modified to allow the colour to mix with water, creating a stable emulsion while retaining the working characteristics of traditional oil colour.

wOil Consistency/Viscosity—wOil has a smooth, buttery consistency, allowing the artist to use it easily. The viscosity or thickness of the colour is medium to heavy body, which can be used directly from the tube or thinned with water or wOil mediums as desired.

wOil Colour and Blending—wOil colours can be blended with traditional oil colours and mediums. WOil Colour is not classified as water-based but can be blended with acrylic-based colours (add a few drops of water).

wOil Colour Luster—The reflective quality of the wOil film varies from colour to colour because each pigment requires differing volumes of oil in the formulation. The addition of water mixed to thin the colour, as well as the use of wOil mediums, will also alter surface lustre.

wOil Permanence—Most artists want to ensure their colours are permanent. Pigment developments have led to continued improvements in the lightfastness of artists' colours, which have been utilized in wOil.

All wOil colours are rated Lightfastness I or II and are recommended as permanent for artists' use. wOil Drying time - When WOil is thinned with water, the water evaporates from the paint film fairly rapidly, leaving behind a traditional film of oil that dries using oxidation. The different drying rates of wOil colours are due to the different reactions of each pigment when mixed with oil. wOil colours should dry between 3 and 5 days, slightly faster than traditional oil colours.
