M Graham's Oil Color Mediums can enhance and heighten oil colors. Designed to decrease drying time and improve adhesion, these mediums are available in a variety of sizes.
Walnut Oil - Perfect for removing color from brushes after use and since it is a natural vegetable oil, it will not evaporate or remove essential oils from the artists' paint brushes. Walnut oil can also slow drying, increase sheen and enhance the flow of oil colors.
Walnut/Alkyd Medium - Can thin the color, enhance adhesion between layers, increase surface sheen and speed up drying time for oil colors. This medium can also increase flexibility of the paints. Walnut/Alkyd Medium is ideally suited for all-prima and glaze applications and is certified non-toxic.
