Frosted bowls are white, and are rough on the outside. They have the thickest walls out of any of the bowls, so they can hold the most vibration and are also the sturdiest bowls. Because of this, frosted bowls are generally the loudest and most vibrant option you can choose. They are much louder than clear bowls or handle bowls. If you would like to play crystal bowls for a room full of people, frosted bowls will give them a full-bodied experience of sound-vibration rather than just an audible experience. Last, frosted bowls are generally the easiest bowls to play. They vibrate quickly, and it is simple to make the bowls vibrate steadily at specific volumes. For this reason you have to pay attention to playing frosted bowls less, and can focus more on the meditation. Generally, a frosted bowl will sustain about 15-20 seconds, though this varies bowl to bowl. Frosted bowls are generally the most popular option, the least expensive, and the simplest to play, so they are generally what we recommend for anybody to start with.
