Baroque Posted November 2, 2019 Report Share Posted November 2, 2019 (edited) Hi I have been trying to using walnut oil instead of linseed oil for a couple of reasons, and after trying several times, I am still having problems getting a varnish out of it. I take 100 ml of resin, boil it at 170-190 degrees for 1 hr, then warm the walnut 20ml oil to the same temperature, and mix them together and keep them at boiling point for about half an hour. Then, after cooling to 120 degrees, I add warm turpentine, about 30 ml. The final product is not impressive, I get a thick and dense mass precipitating at the bottom - rather similar to tar, and a liquid phase on top of it which never mixes with the dense part, which apparently never dries. Did I boil too long or too short time, or too low temperature? Any ideas? Thank you! Edited November 3, 2019 by Baroque Quote Link to comment Share on other sites More sharing options...
