Tung oil

Tung oil is a type of wood finishing product that is derived from the pressed nut of the tung tree. Tung oil is drying oil that is similar to linseed, safflower, poppy, and soybean oil. Drying oils are perfect for wooden objects, since the oil dries to a clear film once it has made contact with the air. Pure tung oil and tung oil finishes are two distinct products that should not be confused with one another.

Tung oil, also known as China Wood Oil, Lumbang oil, Noix d'abrasin (fr.) or simply wood oil, is made from the seed kernels of the Tung tree (Aleurites fordii and Aleurites montana, family Euphorbiaceae).

Tung oil was used as a preservative for wood ships. the oil penetrates the wood, then hardens to form an impermeable hydrophobic layer (repels water) up to 5 mm into the wood. As a preservative it is effective for exterior work above and below ground, but the thin layer makes it less useful in practice.
