Refined walnut oil is a perfect medium for working with natural pigments. Slow-drying, non-toxic, and all-natural! Unlike linseed oil it doesn’t yellow over time.
For creating beautiful natural paints with your pigments, simply scoop earth pigment onto a palette and pour a small amount of walnut oil on top. Mix with a palette knife or glass muller until you achieve a smooth, thick consistency. Walnut oil is also great for thinning and adding fluidity to paint, and for cleaning brushes.
