Peter Hess® Therapy & Bengali Singing Bowls
General Product Safety Regulation (GPSR)
These product safety notes are intended to support the sustainable handling of our Peter Hess® Therapy Singing Bowls.
The production of singing bowls in India, which we revived more than 30 years ago, draws on the knowledge of a centuries-old tradition of artistic metalsmithing. At our local production sites, singing bowls are forged by hand from a bronze alloy made with the pure metals copper and tin. Depending on the singing bowl type, the round shape varies in height, diameter, wall thickness and weight (0.195–14 kg), allowing for different pitches and sound characteristics.
Since every singing bowl is unique, certain deviations from the parameters we define for each singing bowl type are possible. In addition, every singing bowl has individual features that result from the production process. These include, for example, light scratches, discoloration or small inclusions of charcoal. However, these features have no effect on the sound character of the singing bowls, which undergo several quality checks before sale.
Due to the nature of bronze, the singing bowl can react with its environment, especially in humid conditions, and (partially) tarnish. This is a natural process and can also be caused by dirt from regular use and by touching it with your hands and fingers if the singing bowl is not cleaned regularly and/or stored in the fabric protective cover supplied with it. However, any patina that may form on the metal has no effect whatsoever on the sound of the singing bowl.
Each of our singing bowls undergoes several quality controls to rule out defects in material and workmanship and to guarantee the appropriate sound quality. Once it has passed inspection, our Hess Sound quality seal is always placed inside the singing bowl, indicating its quality level (“Premium” or “Classic”). The singing bowls carry an EAN code on their paper packaging. We pack them exclusively in recycled paper with potato starch packing peanuts in cardboard boxes.
The singing bowls should be struck mindfully and not too loudly, as some vibrate in a frequency range that can be perceived as unpleasant if the ear is not at a sufficient distance. The singing bowl can be played by people of all ages. However, due to its potential volume, its weight and its metal nature, children should only play it under adult supervision until they have learned to handle it safely. Always make sure that the singing bowl is positioned securely, as some pieces are naturally quite heavy.
Beyond its actual intended use as an instrument for relaxation, meditation, music or therapy, a singing bowl may also be used for decorative purposes. However, it should not be used as a dish for eating or storing food or as a container for liquids.
If the singing bowl falls to the floor from a greater height, it may break or crack due to its inherent material tension. Usually this results in nothing more than a crack a few centimeters long on the inside of the singing bowl, and sometimes it can even still be played afterwards.
If your singing bowl is damaged beyond repair, you are welcome to send it back to Hess Sound GmbH & Co. KG, and we will take care of its disposal.
