Tung oil or China wood oil is a drying oil obtained by pressing the seed from the nut of the tung tree (Vernicia fordii). As a drying oil, tung oil hardens (dries) upon exposure to air. The resulting coating is transparent and plastic-like; a property which is exploited in most of its applications such as wood finishing, as well as in the composition of oil paints and printing inks.
