In contrast with historians' definitions, granulation of gold and of gold alloys is regarded as an independent branch of the goldsmith's art only insofar as the aesthetic result is concerned; otherwise the technique does not differ significantly from other methods of metal-surface decoration involving joining. Much of the early gold granulation work, such as the examples from Tutankhamen's tomb of 1325 B.C. comprised gold-rich particles on copper-rich substrates, but later jewelry -- Etruscan and other -- used both silver-rich (about 30%) substrates and granules. The granulation of silver alloys never achieved the delicacy obtainable with gold, and ancient granulation work in copper is very rare. The methods of forming the granules and joining them to the substrate are reviewed, and ancient and medieval jewelries demonstrating the decorative effects obtained are illustrated.
