M. Graham : Artists' Oil Medium : 237ml : Walnut Oil Medium

M. Graham Walnut Oil Medium is a natural vegetable oil that enhances the working qualities of oil paint while also serving as a gentle brush conditioner. Unlike solvents, walnut oil does not evaporate or strip essential oils from brushes, helping preserve their condition over time.

Adding walnut oil to your paint slows the drying time, improves flow, and increases sheen, making it ideal for blending and glazing. Although specially formulated to complement M. Graham Artists' Oil Paints, this medium is fully compatible with other artists' oil colours and mediums.
