This varnish tends to darken with age, and is removable with Distilled Turpentine. What is a Varnish? Traditionally a combination of drying oil, resin, and a thinner or solvent, Varnish is a transparent liquid which dries to form a hard, protective film. Why use a Varnish? In addition to preserving artwork, and offering protection against dirt and dust, a varnish evens out the final appearance of the paint, ensuring a uniform finish. Who are Winsor & Newton?
