  • What is 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 (through polymerization ), and the resulting coating is transparent and has a deep, almost wet look.
  • When was tung oil invented?
  • Tung oil, also termed China wood oil, was known outside China about 1760. It was first introduced into the United States in 1896, into Germany in 1897, and soon afterwards into England. Little notice of it was taken commercially in England until after the outbreak of War, when specil water-resisting varnishes were required for aeroplane work.
  • What is tung oil finish?
  • "Tung oil finish" is often used by paint and varnish manufacturers as a generic name for any wood-finishing product that contains the real tung oil or provides a finish that resembles the finish obtained with tung oil. The word "tung" is etymologically derived from the Chinese 桐 tóng.
  • How do you use tung oil diluent?
  • The traditional technique for applying pure tung oil is to dilute the oil 1:1 with solvent, then apply a succession of very thin films with a soft, lint-free cloth such as tee-shirt cotton. Diluents range from traditional spirits of turpentine to any of the new citrus-based thinners to naphtha.
