Martin/F. Weber Co. has over 150 years of artist material manufacturing excellence. With this experience, you are guaranteed that we have selected only the finest raw materials, and carefully formulated them, to manufacture wOil® Water Mixable Oil Paints. The wOil range has been formulated using many single pigments for brilliance of color and clean color mixing. The most suitable oils and dispersion methods have been selected to bring out the individual color 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 color to mix with water, creating a stable emulsion, while retaining the working characteristics of traditional oil color.
