"Safflower oil dries to a robust film, which means that this paint can be overpainted with a low risk of later cracking. It yellows comparably less to linseed oil, and handles in a similar way. This is the most brilliant non-toxic White in my range, suitable for cool, opaque light hues, and generally as a highly keyed mixer." - Michael Harding
