Bowl Information


The Peter Hess® Therapy Singing Bowl with all its vibration and sound features was particularly designed for sound massage. In this context, the frequency range and vibration characteristics of the singing bowl required for the corresponding parts of the body are of particular importance. The sound of the singing bowl is harmonic and without any frequency jumping or ambient noises, as well as free from unpleasant secondary tones (such as e.g. high demanding sounds). The sound spectrum is very rich in overtones and flexible in reaction. Ancient knowledge of manufacture and the material composition provide the basis for construction and production. The most important parameter for optimizing our products is the intensive work with singing bowls and with the Peter Hess sound massage. Research knowledge and a good development work are factors continuously incorporated in our production processes.

The alloy is produced according to ancient recipes. It is first of all casted as a thick slice and after that forged to a singing bowl in a glowing state and in a perfect rhythm by four to five craftsmen. Depending on the size of the singing bowl it is heated around 20 to 90 times. Due to the multiple glowing and cooling processes the singing bowl gets a particularly good sound. Last refinements at the singing bowl are achieved by certain forging techniques. By scraping out by hand the singing bowl is cleaned and so obtains its glossy surface.

The Peter Hess® Therapy Singing Bowl is of a quality that is almost nowhere available on the market. This singing bowl is based on the experiences having been made with the Peter Hess sound massage since 1984 and having been consequently implemented during the development of the singing bowls. For this process, we have built up own workshops. Production is controlled by corresponding experts, among others by an experienced metal engineer. Consequent control processes guarantee compliance with our high quality demands.

Our singing bowls – an alloy of twelve metals

Vibration quality and the sound of the bowl are mainly determined by high-quality bronze (copper and tin). Moreover, further ten metals in homeopathic potencies are added to the singing bowls. For this purpose, a piece of an old singing bowl is melted and added. This process shall remind of ancient knowledge.

Planet Metals:

• Gold – sun

• Silver – moon

• Quicksilver* – Mercury

• Copper – Venus

• Iron – Mars

• Lead* - Saturn

• Tin – Jupiter

*In homeopathic potencies

Further Metals Are:

• Zinc- efficient against states of stress

• Meteor iron- supports energy and activity

• Bismuth- supports the digestive system

• Galena- against arthritis

• Pyrite – for strengthening the lung

What makes our singing bowl so valuable?

Applying pure materials, We exclusively apply pure, high-quality metals, no metals of waste products or scrap.

High contents of tin: Tin is a very expensive raw material, our singing bowls feature high contents of tin. Many other manufacturers frequently reduce the content of tin or replace it by lead (solder), because the price of tin is eight to ten times higher than lead.

Complex forging technique: Our singing bowls are forged from a casted green body and not produced from rolled sheet. Compared to rational production, this means an additional working effort of 30 per cent. Based on the forging technique applied by us, the singing bowl vibrates substantially longer and more consistently. Singing bowls produced from rolled sheet by far do not achieve this sound quality.

High quality standard: From 1000 kg high-quality bronze, about 320 kg Peter Hess® quality singing bowls are made. Amongst others, the reason for this is that we already take singing bowls out of the production process if they do no longer comply with our quality requirements. These singing bowls are melted again then, leading to a loss in material (e.g. because of evaporation of the metals). During “fine-tuning“ of the singing bowl, fine metal fillings are taken from the bowl which can only be reused under heavy losses (caused by evaporation during melting).

Good working conditions and a fair salary for our workers: We care for good working conditions at fair conditions, control that child labor is excluded in our production facilities and provide for regular working hours. Moreover, our workers receive our financial support in the event of illness and ritual festivals within the family or in the religious society.

Strong quality controls: Despite a careful preselection in Nepal and India already, some of the singing bowls produced do not comply with our requirements yet for obtaining the quality seal Peter Hess® Therapy Singing Bowl – professional therapeutic quality. All singing bowls are investigated in Germany with regard to their quality and are classified into quality levels then. All singing bowl sets are individually assorted in Germany. Sometimes we are asked why our singing bowls are not such low-priced as some of those having been acquired e.g. on the occasion of a Christmas market or trade fairs. Comparing them, you will find that our singing bowls, considering the quality features mentioned above, are even particularly favorable in price. Comparing prices, the quality is always important to us. However, it is market standard to determine the price of the singing bowl based on the weight and not on quality.
