Varnish is an important painting tool without which most oil paintings are incomplete. Varnish is a concoction of drying oil, resin and a thinner or solvent. It gives a glossy effect to the paintings and also makes them more durable.
Varnishes are most commonly applied with wide paint brushes. After being applied, most varnishes harden either by evaporation of the solvent, while some harden by oxidation.
