I updated the oil paint brand list with information about the binders used by some manufacturers (Blockx, Old Holland, Michael Hadring, Blue Ridge, and Holbein). I also downgraded my ratings for Blue Ridge. I prefer cold-pressed linseed to alkali refined method they use. They also use a blend of walnut and linseed oils. Finally, I’ve used paint from Michael Harding (ultramarine blue) which seems very good, but I haven’t used it enough to rate it.
