Some manufacturers still follow the old tradition by hand hammering singing bowls and in some cases the results are pretty amazing. Other manufacturers produce singing bowls by pressing, casting and cutting on turning machines, but the work they do pales in comparison to the work of the alchemy masters of the past.
The alloy being used today is quite different from the alloy used traditionally. The secret of various metals proportion is lost and no one seems to be really motivated to find it, because new singing bowls made out of brass have no problem selling today. To make it an even a better sale, modern singing bowls are crafted with various images of Tara or Buddha, lotus flowers and mandalas. I spoke to a woman once who took a very pricey sound healing workshop. Her teacher told her that a singing bowl will not bring any benefits if there isn’t a mandala written on it. And you believed it! - I said (there was no question mark at the end of my sentence).
So what is the main difference between the old and the new metal singing bowl? Usually the old singing bowl will sound softer and sweeter than a new one. The energy it emits has a soul, versus the metallic (although pleasant) sound of the newer one. It varies from one instrument to another and this opinion is certainly not applicable to each singing bowl. Generally speaking, when you get familiar with the acoustic features and go beyond the concept of sonic vibrations, you start to realize the subtle energy that sound is carrying. Most likely you will prefer to work with the old bowl then. In terms of investment, the old bowls are growing in value (approximately 10 % a year) because of the age and the fact that these instruments are vanishing from the market. New singing bowls are growing in value because of the growing price of copper, that's it.Bell of Bliss is strongly considering working with the source of the best quality new made (hand hammered by the old tradition) singing bowls.
