I did a small experiment to see if this indeed is the case. On top of a metal lid, I placed four small blobs of CA mixed with different stuff. Back left: CA+CA, back right: CA+raw walnut oil, front right: CA+BLO, front left: CA+water. In a few minutes, the CA+water and the CA+BLO began to solidify. The CA+CA and the CA+walnut oil remained liquid. After three hours, the CA+CA and the CA+walnut oil were still liquid, but the CA+water and the CA+BLO were completely cured and could be scraped off with a knife. I did not have any raw linseed oil to include in the experiment. I hope that somebody can make that test! Maybe raw LO would react in the same way as raw walnut oil? Maybe the "boiled" property of BLO is what cures CA? Maybe the type of BLO is important. Some BLO is made by pushing hot air through the raw oil, while some BLO is made by adding chemicals to the raw oil.
