Bronze signing bowl with a 5 1/4 inch opening. These are handmade from spun bronze and the sizes vary slightly. Includes wooden beater and cushion. The bowls are made of Panchaloha: literally translated from Sanskrit as five metals. The metal alloys contain copper, tin, zinc, iron and other metals. Singing bowls are played by the friction of rubbing a wooden mallet around the rim of the bowl to produce overtones and a continuous 'singing' sound. They are commonly used for meditation, relaxation, healthcare, personal well-being and religious practice.
