Cold Pressed Unrefined Linseed Oil

Description

Our 100% pure, first-cold-pressed linseed oil is the cornerstone binder for traditional oil painting and encaustic mediums. Extracted gently below 40 °C from premium flax seeds, this oil offers outstanding clarity with a subtle golden tint and an ideal balance of drying fatty acids for robust film formation. Its fast, but controllable drying rate and strong polymer network yield durable, flexible films that support rich impastos, smooth glazes, and crisp brushwork, all while preserving the vibrancy of your pigments over time.

Key Features

First Cold Press: Mechanical extraction under low heat preserves natural tocopherols and minimizes free-fatty-acid content for prolonged shelf life.

Fast Drying: Dries more quickly than walnut or poppy oil—touch dry in 8–12 hours—making it perfect for building layers and swift underpainting.

High Polymerization: Rich in alpha-linolenic acid (ω-3), it forms a strong, cross-linked film that resists cracking and supports long-term stability.

Superior Adhesion & Leveling: Medium-high viscosity that “sticks” evenly to canvas and panels, then levels to a subtle sheen without brush marks.

Archival Durability: Naturally occurring antioxidants guard against oxidative degradation, ensuring decades of color fidelity.
