Granulation in jewelry-making involves the intricate process of fusing tiny metal granules onto a metal surface to create intricate patterns and designs. This ancient technique requires careful control of heat, surface preparation, and adhesion of the granules using tools such as tweezers and a soldering torch. With a rich history dating back to ancient civilizations like the Etruscans and Greeks, granulation continues to be a popular and innovative technique in modern jewelry design for its artistic expression and cultural significance.
