Oil varnishes are prepared according to various methods. In some cases the resin is first melted, oil is added, and the mixture is boiled down to the desired viscosity; in others the resin is added to the heated oil.

Linseed oil is the most important and largely used oil for paints and varnishes. It produces a hard, insoluble film when it dries. The yellow-gold color oil is commercially extracted by various methods. The seeds can be crushed in hydraulic or screw-type presses to produce cold-pressed oil. The same process performed on steam-heated seeds ...
