(The following is the continuation of my post on the Dutch Method thread, but 'off topic' :eek: there...)
Here is my 'secret' technique!
I mix up batches of paint, one palette-pile at a time, so if there is any left over it gets used the next day. I save it on my mixing glass, with a few drops of oil on top and under a sardine can. If several days go by I toss it. Sometimes, if I have a larger quantity (never very much!) of lead white to preserve, I'll seal the pile under a bit of tin foil. Basicly, however, I mix paint as I go. That way it is always fresh, and always how I want it.
LeFranc Bourgois (NOT 'Fragonard'!) 500gm large tubes are good--better than the small tubes--but even they do not have enough oil, so when I use them I mix in more (on the palette, or on the glass). The fundamental problem with tube paint is that if it had enough oil for painting it would separate in the tube, and the storage system--which is the whole point--is spoiled. There is a terrible tendancy for painters to accept tube-paint as the substance with which painting should be done. But the wonders of the oil medium are locked away from those making this mistake. Adding messes of varnish and so on does not really solve the problem.
To properly paint in oils with tube paint it is necessary to add pleanty of oil, until the paint is on the virge--or even beyond!--of no longer being able to stand in a pile. Then the only 'medium' needed is terps. Black oil does the jelly act even better than raw oil, but regular oil does it well enough. For oil paintings it is necessary to use oil, and pleanty of it!
