Rublev Oil Medium Aged Refined Linseed Oil – 8 fl oz is a premium, low-acid drying oil pressed from North American flax seeds and alkali-refined to achieve outstanding clarity and purity. With its light color and uniform quality, this oil is one of the finest linseed oils available for professional artists.

Perfect for multiple studio applications, it can be used to grind pigments into oil paint, thin oil colors, or prepare varnishes. Its low acidity makes it especially suitable for grinding reactive pigments and for maintaining the brilliance of whites and pale colors without yellowing over time.

This medium improves flow and handling, offering artists consistency and control in their painting techniques. Use with turpentine, spike oil, or mineral spirits for custom mediums and cleanup.
