What is boiled linseed oil?

Double boiled linseed oil is a type of wood finish that is made by heating linseed oil and adding driers, such as metallic salts, to the mixture. It is called "double boiled" because the process involves heating the oil twice, first to extract the oil from the seeds and then again to add the driers. Double boiled linseed oil is used to protect and enhance the natural beauty of wood and is often used on furniture, cabinetry, and other woodworking projects.
