dc.description.abstractTobacco seed oil was expressed from the seed and purified by centrifuging. Four interior varnishes were prepared. Three of these varnishes contained tobacco seed oil as one of the drying oils. A satisfactory interior varnish was prepared using tobacco seed oil, which had been heat-treated at 585ºF for six hours and attained a viscosity of 7.65 poise at 77ºF, and dehydroxylated castor oil at a viscosity of 46.3 poise at 77ºF as the drying oils. This prepared varnish compared favorably to a standard interior varnish when tested for drying time, color, viscosity, and condition of dried film. The viscosity of the standard varnish was 3.1 poise at 77ºF and the viscosity of the prepared varnish was 3.1 poise at 77ºF. The during time of the standard varnish was (1) indoors - 12 hours (2) outdoors - 7 hours. The drying time of the prepared varnish was (1) indoors - 16 hours (2) outdoors - 10 hours.en
