However, their handling is slightly different: when thinned with water to a considerably liquid phase, water miscible oil paint tends to feel and behave like watercolor (although, unlike watercolor, and to a greater extent than traditional oil, it may lose adhesion to the ground or support if over-thinned); by contrast, when used as a short paste without water for heavy impasto work, it tends to drag, developing a consistency somewhat "gummier" or tackier than the more buttery one characteristic of oils.
The handling of water miscible oil paint, in summary, changes considerably as it passes from one phase to another.
[7] 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.
[citation needed] Although this type of paint may be thinned with water, artists may prefer to use specially prepared mediums for improved texture and control.
These mediums improve flow (i.e., make the thinned paint less runny and more easily controlled) and can slow or speed up drying time.
