What are Crystal Bowls, Bio-Sonic Bowls or Crystal Technology? They are delicate concave vessels of pure quartz crystal, which when gently rubbed with a specially designed wand, are capable of emitting sound impulses of high vibratory quality, which can expand up to 8 kilometers away.Quartz crystal singing bowls are based on the tradition of using sound with metal bowls in Tibet, India, China, Japan and other Eastern countries for hundreds of years for meditation and healing. For this purpose they began to be used at the end of the eighties. How are they manufactured?The quartz crystals (crushed) are loaded as tightly as possible in a graphite or carbon crucible, so that when the crystals break, due to the effect of heat, their fragments cannot separate, thus preventing the entry of small particles. amounts of gas that would cause bubbles and faults in the quartz bowls.The crucibles are placed in a modified vacuum furnace, the temperature of which is raised as quickly as possible to the melting point of the quartz. The oven pressure must be kept as low as possible. The fusion of quartz in a vacuum requires 6.6 to 17.6 kWh/kg.The product of the fusion is a transparent magma that is subsequently placed in another graphite crucible. This paste is passed to a centrifuge mold that gives the shape to the quartz bowl. Mineral composition of Crystal BowlsThe mineral quartz (SiO2) is the most common and widespread mineral (it makes up 12% of the Earth’s crust); It is composed of silicon and oxygen in a ratio of one to two. It belongs to the class of silicates and the trigonal crystal system.This mineral is very rich in varieties, it can be grouped into macrocrystalline, with crystals clearly visible to the naked eye, and cryptocrystalline, formed by microscopic crystals. The first group includes pure quartz (hyaline or rock crystal), colorless and transparent, and varieties that have different colors: violet (amethyst quartz), brown (smoky), black (morion), yellow (citrine), etc. The second group includes important varieties such as chalcedony, jasper and flint, which comprise various subvarieties.As dioxide it is found in various forms: Rock crystal, Amethyst, Smoky quartz, Rose quartz, milky quartz, among others. Quartz is an extremely stable and hard mineral (7 on the Mohs scale). It is the second most abundant element in the Earth’s crust after oxygen. Silicon, unlike carbon, does not exist free in nature.musicological analysisCrystal bowls produce two main musical structures, which, in turn, affect humans in a beneficial way:Harmonics.- Pure and ordered sounds in a succession of notes. The musical degrees to form this structure are: I, III, V, VII, VIII. These sounds generate connections with the great creative force.Beats.- “Supplementary” vibration that decreases when two sine waves approach the point of perfect tuning. These sounds generate synesthesia.
