The secret science of Tibetan Bowls is still a mystery to the West since the Tibetan monks aren't talking about it to the uninitiated. The Singing Bowl Book by Eva Rudy-Jansen, however, explains a lot of the lore that is available about them. A special type of alchemical metallurgy is used that combines various metals, apparently having to do with the energies of different planets. According to tradition, the bowls are made of seven metals each corresponding to the following planets: Sun - gold, Moon - silver, Mercury - mercury, Venus - copper, Mars - iron, Jupiter - tin, and Saturn - lead.p There are a lot of Singing Bowls on ebay and we understand how hard it is to choose.
