Sarthebari is home to the bell metal industry of Assam. The craftsmen still follow the indigenous process of melting the raw material. After hammering the raw material into small pieces these are put inside an iron vessel and placed in the fire vent. Once it takes a complete molten form, the iron vessel is taken out and the hot liquid metal is poured over the flat round surface of the earthen crucibles which is previously dabbed with mustard oil.

The molten metal solidifies forming small round, bell metal ingots. These metal ingots are then again burnt in a fire vent, to soften them and are then hammered continuously to give them the required shape. After the rough shape is formed, the bowl is beaten with a small hammer to give it a final shape.
