I used to think stand oil was non-yellowing, that's what I had read,
but as I can see in this test, it does yellow.
It's very annoying to stroke over an area and not blend into it or
lay over it, the wet under paint lifts off if you use just standoil.
Stand oil would rather stick to itself than to the canvas.
Mixed with turpentine it becomes workable but the strokes change by
themselves AFTER the stroke has been painted (flow-out and bleed-over).
It does find it's way into my most paintable oil medium though.
