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 stand oil.
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.
Today, 7-15-13, I'm ready to photo the paint tests of 1995 for an 18 year test, the best non-yellowing mediums are:
wax, damar, poppy oil, Venice Turpentine, cold pressed with damar and cold pressed linseed oil.
Stand oil didn't make the grade, maybe it wasn't made with cold pressed, they don't tell you on the label.
I wish they had alkyd paint back then, I would love to have been able to compare them to it. Love the way it paints!!
