Jaipur has been the hub of crafts and crafts people since ages. Thathera is a Hindu community, found mainly in North India. They are traditionally involved in the production of household utensils primarily made from metals like copper and brass. In Rajasthan, Thathera craft can be found in Jaipur and Jodhpur. These two districts being the hub of the craft have a good number of people belonging to Thathera community. The process of making utensils using Thathera technique is easy yet time consuming. The sheet (brass, copper or iron) is first straightened. After this with the help of scale, marker and compass markings are done on the metal sheet for the product to be made. In the next stage the sheet is cut either by chisel (if thick) or by metal scissor (if thin). Once the sheet is cut it is placed on Bangad and hammering is done with wooden mallet or hammers. The products are made in parts and finally joined either by heating or by gas welding. Once the product is joined the excess metal accumulated on the surface due to welding is removed by grinding machine or files. Then these items go through acid wash to clean the surface. The product is then buffed using buffs of different grades/numbers.
