Tamta Mohalla is the famous locality in old city of Almora renowned for skilled coppersmiths. The copper sheet is beaten to make it flat. The design outlines are marked on the product as per the shape of the product to be made. The copper sheet is then cut with scissors. Now, properly cut copper pieces are sent for annealing and shaping process.
Heating process is also called annealing which is done to strengthen the copper sheet. The process of heating and beating is repeated until the required shape is obtained. After heating and shaping, the partially shaped copper pieces are allowed to cool at room temperature.
The motifs designs are engraved on the surface by chiseling and beating processes. The parts of the product are made separately and then joined together. These joined parts are soldered. The product is again heated on furnace then allowed to dry. After soldering process, the product is washed with diluted acid solution. Finally it is washed with tamarind solution to obtain more lustrous look.
