A heavy-bodied purified oil that is thicker than regular linseed oil but not as thick as stand oil, Grumbacher Sun-Thickened Linseed Oil is designed for use in preparing oil painting mediums.

Still made by the orthodox method of exposure to the sun for prolonged periods, this oil is very heavy and thick, with a viscosity that improves drying, leveling and protective characteristics. Used with oil mediums, varnishes and glazes.

Faster drying than Stand Oil, this pale, heavy-bodied oil has the properties of a sun-thickened oil. It’s superior to other heat-treated linseed oils when used with painting mediums.

This authentic, sun-thickened linseed oil is made in the slow, traditional manner during the spring and summer months and comes in limited stock. It increases the flow, transparency, and gloss of oil paints and can also be useful as an ingredient when making your own painting mediums.

A pale refined oil of syrupy consistency, Winsor & Newton Thickened Linseed Oil speeds drying time even more than Winsor & Newton Bleached Linseed Oil. It improves flow and gloss, and increases the durability of the film. This oil behaves like Linseed Stand Oil but dries quicker and darker.
