Crystal Singing Bowl Set

The natural quartz crystal is crushed in a delicate pulse grinder that retains more minerals in the crystal. The crushed crystal sand is heated to exactly 4001.47 degrees in a centrifugal mold. When the temperature reaches 3995.58-4001.47 degrees, the sand becomes liquid, these are cooled into our amazing crystal singing bowls.
