Sun-Bleached Linseed Oil is made by exposing raw, cold-pressed linseed oil to sunlight in shallow tanks covered with clear glass for a period of more than one month. No driers or other additives are used in the making of this oil. The exposure to sunlight lightens the oil considerably but only slightly thickens it. This linseed oil has about the same color as or lighter, so it can be used with pale colors and white. This oil can be used as a medium or added to homemade mediums.


This linseed oil is less yellow than walnut oil, so it can be used with pale colors and white. It is fast drying. This oil can be used as a medium or added to homemade mediums.

Use turpentine, spike oil or mineral spirits as a solvent or diluent for oil painting mediums made with linseed oil.


Prepared by exposing linseed oil (derived from the dried ripe seeds of the flax plant [Linum usitatissimum, Linaceae]) to sunlight for at least one month.
