Stand oil is heat treated and polymerized (thickened) oil. This heat-bodied oil is made from well-refined linseed oil from American flax seeds that is cooked in closed-kettles. Kettle-Bodied Linseed Oils are heat-polymerized oils made in closed-kettles. They are of medium acid range and light color.

Kettle-bodied linseed oil is a stand oil that gives gloss, brushabilty and low-yellowing characteristics when compared to other stand or bodied oils. Bodied oils form harder films than raw or refined linseed oil, including cold-pressed oil.
