I began washing flaxseed oil and sun-bleaching it until it was water clear. The color seemed to be better in the lighter hues and the whites looked very bright. I could grind my whole palette now with one oil, but it was missing that black oil special feeling and it took much longer to dry.
I then thought to cook the water clear oil with litharge similar to making black oil. I bounced the heat for at least 5 hours and the oil only got slightly darker but still much lighter than cold-pressed linseed oil. After letting the cooked oil sit for a couple of days I tried to make some Maroger. It got stiff but didn't completely gel. I put some in a jar and to my surprise a week later it became thixotropic! The resulting medium is a very light similar to Liquin or other neo-megilps but much more transparent. Now I can gring my paint and make my medium with the same, stable drying oil.
