Cold Pressed Pale Walnut Oil

Description

Our 100% pure, first-cold-pressed walnut oil is the premium binder for your most refined oil painting and encaustic formulations. Extracted gently at low temperatures from select English walnut kernels, this oil retains its natural clarity, subtle nutty aroma, and an optimal balance of fatty acids for archival film formation. With a moderate drying rate and exceptionally low tendency to yellow over time, it allows artists to achieve buttery impastos, seamless glazes, and crisp detail without compromising longevity.

Key Features

First Cold Press: Mechanical extraction below 40 °C preserves delicate compounds and antioxidants, minimizing free-fatty-acid content and rancidity.

Low Yellowing Index: High linoleic/palmitic ratio and natural tocopherols yield a crystal-clear film that stays true in cool whites, pastels, and pale tints.

Balanced Drying Time: Dries more slowly than safflower but faster than poppy oil—ideal for both wet-into-wet blending and building translucent glazes.

Superior Viscosity & Leveling: Medium body that sits perfectly under heavy bodied pigments yet levels out without brush marks for a silky finish.

Archival Stability: Naturally rich in antioxidants to guard against oxidative degradation, ensuring decades of color fidelity.
