Beaten or hand hammered singing bowls are made by complete hand hammering process. In beaten singing bowls, every single singing bowl are carefully hand beaten which requires several processes to finish up and shaping into a perfect hand hammered singing bowl.
In the making process, first the various composition of metals as raw materials (Copper, Tin, Zinc, Iron, Lead, Gold and Silver) are melted into furnace depending on manufacturing needs such as for bronze singing bowl or for seven metal singing bowl making. The hot melted metal are taken from furnace and poured into a Gulli Cup or Dice to prepared metal mould for the various size and weight. Then, the round metal gulli or moulds are taken to make rolling and turn into round metal sheet in needed size and thickness. After that, the sheet are brought for the hand beating or hammering process after precise measurement and categorized for weight and sized bowls.
Regarding hand hammering process of singing bowls making, 4 -5 round metal sheets are piled up one upon another and then heated to red hot burn. The red hot burned metal sheets are hammered from a group of expert artisan till the heat remains in metal, and again processes to red heating for continuous beating for the singing bowl shaping. This heating and beating process with the bundled and piled up metal sheets continues until a desired shape and size forms from a metal sheet. (That is why the hammered or beaten singing bowls will get proportionately difference in a size centimeter with each individual singing bowl).
In hammering process of these singing bowls, the metal sheet must hammer and beating on the time of red hot only which remains softness and flexibility on the metal, this is because as the metal getting colder, will loose its softness and flexibility which in turns tampered and gets hardness on metal, and thus breaks metal or bowl if done hammered. The reason behind this working process is the metal content Bronze or Seven Metal mixture is very sensitive to heat and gets harder if it looses it hot temperature and will have cracks and breaks if works. So in this shaping stage of hammered singing bowls, the makings are done with the duration of hot metal only.
