Natural Pigments Refined Aged Linseed Oil is a medium-acid value drying oil pressed from North American flax seeds. This is as light and pure as industrially-produced linseed oil can be made. Use to grind colors, thin oil colors or prepare varnishes.
Linseed oil is a yellowish drying oil derived from the dried ripe seeds of the flax plant (Linum usitatissimum, Linaceae).
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 closeable, 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.
