It is said that William Ashton Taylor boiled the Vulcanite which he used in the manufacture of stems for his Ashton pipes, and that this helped reduce the oxidation. It is also reported that the process created a horrible stench!
Wow, I have had the same experience. A long time ago, before the internet and before I could read about oxidation and how to fix it, I had a peterson go to hell Over a week or so.
It tasted awful, It may have even smelled awful. I had no idea what had happened.
In hindsight, I think it was in direct sunlight.
Years later, oxyclean and polishing have given it new life.
