Sun-Thickened Linseed Oil
Rublev Colours Sun-Thickened Linseed Oil is made by exposing raw, cold-pressed linseed oil to sunlight in shallow enamel trays covered with clear glass but exposed to the atmosphere for more than on year.
Rublev Colours Sun-Thickened Linseed Oil is made by exposing raw, cold-pressed linseed oil to sunlight in shallow tanks covered with clear glass and exposed to the atmosphere for one year. Exposure to sunlight lightens the oil considerably but only slightly thickens it. To give the oil more body (higher viscosity), we blow air through the oil for at least one year.
This linseed oil is slightly more yellow than sun-thickened walnut oil, so it can be used with pale colors and white. 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. Linseed oil is a yellowish drying oil derived from the dried ripe seeds of the flax plant (Linum usitatissimum, Linaceae).
