Walnut Oil and Walnut Alkyd Medium
Walnut/Alkyd Medium was developed to provide artist's with a non-toxic, environmentally responsible alternative to solvent based, rapid drying alkyd mediums. This is a medium that closely resembles the wonderful combinations of sun-thickened oil and natural resins used so effectively throughout the history of art but with the singular advantage of being free from solvents.

Walnut Oil dries glossy. While you shouldn't make it matte, wax can be dissolved in the nut oil and will impart a semi-matte finish.
