(1 : 1 : .5) Graham Walnut Oil : Galkyd Lite : Gum Turp

After using this it seems as though I'm using straight walnut as far as drying time goes however I'm not entirely convinced the two substances are mixing together well enough. It just seems that some of the walnut oil inevitably sits on top of the Alkyd which has gasped for air through the walnut to dry itself before the walnut - it even feels like the walnut sits onto of something - and that would be the Galkyd lite.

Would cooking, heating, or boiling these together create a better bond or is this pointless ? The whole idea of this was increase flexibility of the walnut and drying speed and avoid Grahams own version which seems terrible in review. Maybe I don't have enough turps ? It just seems weird to me, of all the other mediums I have experimented with this one does not bond well. In review of this medium, aside from fluidity and yellowing factor I'm beginning to think walnut is inferior to linseed or even Gamblins Galkyd Lite frankly.

I plan on replacing my walnut oil (or at least trying NP sun thickened version in place) in all my mixes with a fast drying, fluid, minimal yellowing linseed type oil. I want to try NP black oil but is that enough on its own to get what I'm after? Is NP Epoxide good to mix with others like venice turp and stand oil? What is a good fast dry, low yellowing, fluid NP linseed type oil.

I've also been playing around with NP Damar and stand oil mixes but aside from the drying time of damar it just looks like the stuff on its own was born to crack in due time - its says "brittle" to me ? I'm also confused on using it with your medium then varnishing which you hear may pose problems when trying to clean varnish in 100 years and inevitably removing some of the painting with it. Does using a completely different "synthetic" type varnish detour this problem ?
