Crystal singing bowls are similar to the tibetan singing bowls used by tibetans for thousands of years for meditation, healing and balancing. The tibetan singing bowls are generally made from a bronze alloy containing copper, tin, zinc, iron, silver, gold and nickel. To play a sound you either strike it with a wooden or leather-wrapped mallet or rub the mallet on the rim. This causes the bowl to vibrate and producing a rich sound. The same physics can be observed by rubbing your finger on a high-quality wine glass.
It is only in the past 20 years that technology has enabled people to create singing bowls using crystals. Crystal singing bowls are made of 99.99% quartz crystals and because of the crystal energy, it creates beautiful angelic sounds. The tones produced are heard not only by the ear, the vibration can be felt in the body and your energy centres (chakras). Similar to the tibetan bowls, the tone and quality of each bowl is unique even if they are phyically of the same size, their voice imprint is different.
There are different types of crystal bowls – basic quartz bowls, alchemy bowls infused with other crystals or metals.
