Each casting is used up to the last drop of molten metal. The workers are well aware of the toll it takes to dig it out. The remaining metal can be used to fill small moulds kept for this purpose. It takes years of training for these artist-workers to achieve the precise gesture. Each object that is shaped requires great dexterity and good workers are highly sought after. The quality of the casting determines the quality of the pieces produced. The whole production chain thus depends on it.
