of the paint (as a general rule, the pastier, the glossier). The handling of water miscible oil paint, in summary, changes considerably as it passes from one phase to another. This makes it a versatile medium but, by the same token, it also requires the artist to develop by experience specific skills with which to successfully manipulate it and exploit its range to achieve the desired effect. Although the practice of mixing water-mixable oils with acrylics is possible (as some brands claim), it is not recommended if the painting's longevity is a concern. The reason is that once the acrylic dries, its impermeability isolates the oil from oxygen, preventing it from oxidizing properly. Since each manufacture of these paints has its own formula for creating the water-mixable capacity, the following should be checked with each manufacturer’s paint. As the artist writing this paragraph uses Lukas Berlin water-mixable oils, the following applies to Lukas Berlin. They are quite stable on acrylic gesso primed surfaces. Therefore, after all polymerization has occurred, when subjected to a damaging force can with stand quite some force without suffering damage to the paint film. The same is not true when they are applied to oil primed, or oil ground surfaces, i.e., canvas, canvas board, or paper. When fully dried the paint is not fully attached to the oil primed surface. It is easily damaged by any force acted upon it. Subsequent testing has established that Royal Talents’ - Cobra, Holbein Works’ - Duo and Daniel Smith’s - Water Soluble Oil Colors also exhibit the same problem with oil primed surfaces. In a lighter vain, the other thing you shouldn’t do is to paint in the rain with water mixable oil paints. An artist friend who paints in all kinds of weather with traditional oils was doing just that when he noticed that the paints, he had mixed with white, were running. The tube of white paint a friend had given him was water mixable. However, after completing the oxidation process (completely drying) the surface is as strong as traditional oils and cannot be reactivated with water. Brands There are several manufacturers producing water miscible oil paint, including: Daler-Rowney (Georgian Water Mixable Oil);Mont Marte (H2O Water Mixable Oil); Daniel Smith (Water Soluble Oil Colors); Grumbacher (Max Water Mixable Oil); Holbein Works (DUO); Lukas (BERLIN); Martin F. Weber Co. (wOil); Reeves (tube sets and complete painting set); Royal
