The extraction method of pure and ripe tung oil is to stir fry the tung seeds and extract the oil, without artificially adding any chemical components. It is suitable for environmentally friendly and pollution-free decoration, especially indoors. Mixed and cooked tung oil belongs to a type of paint, which is blended in a 2:2:6 ratio. 20% varnish, 20% rosin, and 60% tung oil are heated and boiled to a temperature of 260 degrees Celsius.
