Composition of crystal singing bowls Every crystal singing bowl consists of 99.992 % pure, pulverized quartz crystal (silicone quartz SIO2), pressed at 3.000° Celsius. The pure sounds are able to set our body into vibration, because it has a natural affinity with quartz (among other elements). The human body is composed of many crystalline substances. Even on a molecular level, for example, our cells contain crystalline silicid acid. This substance helps to balance our natural electro-magnetic energies, and also happens to have the same chemical formula as natural quartz crystal! Music from quartz crystals contains the vibration of white light, which is dispersed naturally into the rainbow spectrum, before flowing directly into our chakras, and their corresponding physical areas.
