How Quartz Crystal Singing Bowls Are Made
Crystal bowls are made from highly purified quartz powder which is fused together at high temperature. They are used to grow large single quartz crystals under highly controlled, clean conditions to make silicon chips and also for use in high temperature chemical processes where other containers would not stand the temperature. There are different sorts of crystal bowls and they are made using different processes.

Frosted Quartz Crystal Singing Bowls
Frosted quartz crystal singing bowls are the most common type of crystal bowl and are so named because of their translucent rather than transparent appearance. This type of bowl was developed for growing quartz crystals to be made into silicon chips. Absolute purity and cleanliness are essential for this so the quartz powdered used for making these bowls is highly purified - only a few parts per million of impurities are allowable.
The bowls are made using a carbon mould. This is spun and a metal arm follows the shape of the mould a few millimetres from the inside surface. Quartz powder is poured in to the rotating mould. Electricity causes an arc to jump to the mould and the heat from this fuses together the particles of quartz to form the bowl. This is all done in an enclosed computer controlled machine. The crystal bowl is removed from the mould when it has cooled and the top rim is cut to height. Looking at frosted bowls you can see the graininess on the outside caused by the small pieces of quartz used in its construction. The inside of the bowl has a smoothed and polished appearance caused by the electric arc.
Frosted bowls are in larger sizes from about 10 inches (30cm) upwards. They are generally played with a rubber ball stick and a ring is used to hold them steady as the base is rounded. The playing stick and ring can be seen in this photo.

Clear Quartz Crystal Singing Bowls
These are made from pieces of clear quartz tubing. A length of tubing is cut and fitted on a lathe. As the lathe slowly turns burners heat the quartz so that the shape of the crystal singing bowl is formed. This is a highly skilled process. Clear bowls are played with a different kind of rubber ball stick shown in the photo which uses much harder rubber. Like the frosted bowl it sits on a rubber ring (not illustrated) to keep it steady and make it easier to play.
Quartz Crystal Practitioner Bowls
The photograph shows a Quartz Crystal Practitioner Bowl upside down. It is a clear singing bowl mounted on a tube handle. The handle is welded to the clear bowl. Other producers of practitioner bowls have had problems caused by a weakness where the heat used to weld the handle has set up a stress causing breakages to happen. Our manufacturer has perfected this process and removes the stresses after the welding.
Practitioner bowls are played by holding the handle in one hand and using a hard rubber ball stick (illustrated in the clear bowl picture above) to produce the sound. Obviously no rubber ring is needed.
