Winsor & Newton Artisan Water Mixable Oil Thinner is designed for diluting Artisan Water Mixable Oils. It has been specially developed to maintain the oily feel of Artisan oils and keeps colours open longer than water.
Although water is suitable as a diluent for the colour, its speedy evaporation can make the colour thicken on the palette much quicker than conventional oil colour would when used with solvent thinners. As Artisan thinner does not form an emulsion with the colour, there is less colour change than there would be with water.
Artisan Water Mixable Oil Colour has its own specially developed range of mediums, varnishes, and solvents, so that all the techniques available to traditional oil painters can be achieved with Artisan oils.
