Rublev Colours Walnut Oil

Cold-pressed from freshly dried English walnuts (Juglans regia) grown in California and then lightly refined. It is a clear, pale yellow oil that is odorless. As a thin oil, it makes oil paint more fluid. As it yellows less than linseed oil (but more than safflower oil), it is suitable for making pale oil colors. Walnut oil dries more slowly than linseed oil, drying in four or five days. It is said to have a less tendency to crack than linseed oil, but research has not verified this.

This oil is used to make oil colours and thin oil colours. It is excellent for making and thinning whites and pale colors.

Because of its safety and odor, some woodworkers prefer walnut oil as a finish for implements that come in contact with food, such as cutting boards and wooden bowls. People who formulate wood finish value walnut oil as an ingredient because of the edibility of both ingredients. The oil is typically combined with beeswax in a mixture of 1:2 oil to beeswax.
