Walnut Oil

11 January 2011

Cold-pressed walnut oil is filtered with no additional treatment. It yellows less than linseed oil. It is closer in drying time to poppy oil than linseed, but dries faster than the former. Its viscosity is lower than that of linseed, and it can generally incorporate more pigment as a binder. The chemist Tingry noted in the mid 19th century that nut oil is more weather and UV resistant than linseed oil, despite forming a somewhat softer paint film.

Walnut oil has a shorter shelf life than other oils and can spoil.

Sun-thickened walnut oil is only slightly more viscous, and becomes paler in color.

    What about cold-pressed Hemp Oil? I understand it is a drying oil and has an iodine value of 150 – 167. Is it useful for an oil painting medium, pigment binder, or brush cleaning? I like to use a drying oil for brush cleaning because I suspect a healthy amount makes its way into my painting :)

    Lots of technical info. You cover the important differences between the oils very well. I love stumbling onto websites like this where I actually learn more. Thanks.
