One story that is being circulated is that the bowls contain seven sacred metals. The idea of the seven metals comes from the Sacred Seven Metals of the region, gold, silver, copper, tin, iron, lead and mercury. Bowls made with large quantities of all these metals would not sing. What is actually found in almost all metal bowls that sing, whether ancient, or modern, is a common base of 80% copper, and 20% tin. This combination is commonly known as bell metal. In traditional metal bowls, the other metals occur only as trace elements.
Whether dealing with a weathered antique bowl covered in primitive etchings, or a modern bowl made for intentional healing, no one can deny the natural power of the sound produced by these wonderful instruments. Everyone has their own special story of their “first time” experience with the bowls. People who encounter them are often mesmerized, and gain a moment of mindfulness with their initial experience. Not everyone will embark on a journey of therapy and meditation, but all who encounter the bowls are touched.
