No doubt this is the winning natural oil, look at that test area, it's almost as clear as dammar mastic, Venetian balsam or wax.

Today I checked the paint test results of 1995 for an 18 year test report,
the best non-yellowing oil mediums are:
wax, damar, poppy oil, Venice Turpentine, cold pressed with damar and raw cold pressed linseed oil.
None of them changed in 18 years.
Another yellow test with W/N linseed done in 2000 did yellow, maybe it was a bad batch??
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 we had alkyd media to compare back then, I love the way it paints and dries so quickly.
