Safflower oil is a very slow-drying oil found in most oil paints. Gamblin Safflower Oil can be added to oil colors to increase flow and slow down drying time. Use sparingly when mixing with Gamblin oil colors and apply mixture thinly to ensure proper drying and avoid wrinkling. You can also mix equal parts Gamsol and Gamblin Safflower Oil to create a slow drying but high flow painting medium. Safflower oil can be used to clean brushes while painting.
