Tung oil

Tung oil or China wood oil is a drying oil obtained by pressing the seed from the nut of the tung tree (Vernicia fordii). Tung oil hardens upon exposure to air, and the resulting coating is transparent and has a deep, almost wet look.
The name is often used by paint and varnish manufacturers as a generic name for any wood finishing product that contains the real tung oil and/or provides a finish that resembles the finish obtained with tung oil.

Derived from: Tung nuts (Aleurites fordii)
Main growing areas: China, Paraguay, Argentina
