Michael Harding Refined Safflower Oil Medium is a very pale, slow-drying oil medium used to brighten and thin oil colors, especially whites and pale colors, helping them retain their clarity and brightness. Due to its slower drying time, paints mixed with safflower oil should not be applied before faster-drying layers—such as those containing quick-drying mediums or earth pigments—to avoid issues with cracking or adhesion. - Michael Harding Refined Safflower Oil Medium - 100 mlMichael Harding Artist Oil Medium, RFN SFLWR 100ML -
