Stand Oil is a very heavy bodied oil. It wets pigments well, producing paint with good flowing qualities that levels easily and reduces brush marks. A more durable type of Linseed Oil, Stand Oil is partially polymerized by being heated in the absence of oxygen, thereby producing a longer drying time. It is therefore a good glazing medium. It also increases gloss and transparency.
Richeson Mediums are tested in accordance to: ASTM D-4236 and bear safety labels to the standards issued by ACMI. While some Richeson mediums are AP approved non-toxic, certain mediums bear the CL label with safety warnings.
