I did actually follow his directions very closely. I broke up the pieces. I don't remember how long I let it work, but I think about 2 weeks. Got the nice yellow clear liquid and decanted, and let alcohol evaporate. I know the Copal I have is the exact same as damascus pictured. Now, I am questioning the alcohol I am using. It is denatured alcohol. So, what I am doing is starting another batch. I will follow the directions to a T. I will let you know the results. If I get the same results, I think I will get some different alcohol. I have found it on line from the chemical supply companies also.
