PREVIOUSLY CALLED MICHAEL HARDING REFINED PORTUGUESE TURPENTINE
Refined Gum Turpentine is a colourless solvent distilled from pine sap. It is used to thin oil paint and to clean various printmaking tools of oil-based ink. It generally speeds the drying time of oil paint and thus is especially useful for underpainting. Paints mixed with this Turpentine will dry slightly matt.
