Sun-thickened linseed oil

Sun-thickened linseed oil is made by raw linseed oil being poured into large containers outdoors and left to stand and become influenced by sunlight and oxygen. The process continues for a period of 3-4 months during which time the linseed oil bleaches and thickens through oxidation. This is the old method of producing “Linseed stand oil” and cannot be compared with modern methods of producing stand oil. Sun-thickened linseed oil is the product used in artwork oil paints and older craftwork paints and is mentioned in texts dating from the 17th century. This oil has very good drying and gloss properties with good resistance to UV light.

Used as a medium in our artwork oil paints to enhance the drying and gloss qualities of the paint.

Sun-thickened linseed oil can also be used as an additive to our linseed oil paints in the final application. We recommend its use in our darker shades where the result is a beautiful deep gloss. Add approx. 10 to 15 volume percent to the paint.

NOTE! If added to white or light grey shades, the paint may thicken.
