Hi I got a few horns from a friend at the abattoir. They are fresh, with pieces of skin bloody stuff still on the ends. I do not have any knowledge about how the horns have to be treated but was told the first step is to boil the horn to loosen the inside part. Being worried that everything was going to become very smelly soon, I started boiling the horns with a few hands of salt thrown into the water. Did I start right? How long to keep up this boiling? Any help much appreciated
