Stand oil is a drying oil that is made from the extracts of flaxseed or linseed. This oil is easy to apply and provides an excellent finish for oil paintings. It is also known as bodied oil, heat-bodied oil, and polymerized oil. Bodied oil refers to stand oil that has been thickened to increase its viscosity, making it more resistant to drying and allowing it to be easily applied. Heat-bodied oil is another name for stand oil that has been heated to improve its properties. Polymerized oil is a term used to describe the natural process of oil becoming thicker and harder over time. Whatever the name, stand oil is a favorite medium among artists for its durability, ability to dry quickly, and enhance the richness of colors.
