Granulation is the process of joining tiny balls of precious
metal to a surface. When a tiny piece of silver or gold is heated to melting point with a tip of a blow torch the metal pulls itself into a
perfectly round ball. I remember this as magical
thing to do as a child, playing with scraps of silver and
copper with my grandmother...These grains or shot are
called 'raindrops' in Native American metalwork.
