Birch Bark Adhsive II

I have processed the oil from birch bark, but saw you could purchase it online.  I thought I would try it and make some hard birch tar for hafting.  It took several hours simmering it, evaporating the volatile ingredients.  I added finely powdered charcoal and it cooled to a hard consistency, some brittleness, but not as much as pine pitch.  It is a smelly process that permeates your hair and clothes and irritates your wife.  Now I need to haft a point and assess the strength.
