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 a period of one month. Exposure to sunlight lightens the oil considerably but only slightly thickens it.
To give the oil more body (higher viscosity), we place lead sheets in the tank and blow air through the oil for at least three more months. Trace amounts of lead may dissolve into the oil and may be present in the finished oil.
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).

Health and Safety
Warning: Rags or paper towels contaminated with vegetable drying oils, particularly those containing iron oxide pigments are susceptible to spontaneous combustion. To prevent unexpected fires, used rags or paper towels contaminated with oil-based materials should be collected in a closable, air-tight container. Store water-dampened rags or paper towels in a metal container with an air-tight top. Alternately, washing contaminated rags will remove contaminating materials and eliminate risk.
WARNING! CONTAINS LEAD. HARMFUL IF SWALLOWED. Avoid ingestion and skin contact. Wear protective clothing and gloves to prevent contact with skin. Never use near children or pets. Conforms to ASTM D 4236.
