[book] A Short History of the Art of Granulation

Does anyone know how I could get a hold of a research article by
Jochem Wolters entitled, “A Short History of the Art of Granulation”

thanx

Wolters was a regular contributor to the german publication
’Goldschmiede Zeitung’ which is published by the Ruhle-Diebner Verlag.
They have a web site, which shouldn’t be dificult to locate. They have
kindly sent past articles when I was doing some research. Good luck.
