What is Granulation?
Granulation is a very ancient process of taking TINY spheres of metal and attaching them to another metal WITHOUT soldering. The pieces are attached so that the two metals fuse together at the point of contact. Many methods for granulation are used, some of them considered proprietary or even secret. Most jewelers who are practitioners of this art have their own method. In the simplest terms: The granules are stuck to the metal in a design or pattern using an organic glue. An oxygen free, high temperature, environment is produced around the granules and the metal. The metal at the point of contact surface melts BEFORE both pieces melt into a big blob. The granules and the metal are thereby fused together. For a picture , click here.
