The Chakar Kalanga is a traditional wooden vessel of the Rabha tribe found in the states of Assam and Meghalaya. The vessel has been painstakingly carved out of a single piece of wood and is smooth on the cylindrical exterior but rough on the interior: this could help to grip the contents or mix them well. This vessel has a circular opening at the top and probably is a practical household vessel for keeping grains, liquid, or processing food materials.
The vessel is supported by three carved wooden legs, giving it both elevation and stability. This tri-leg design further shows the indigenous understanding of balance and function found in tribal artifacts. The lack of any external decoration or embellishment implies that it had been made for everyday use; nevertheless, the craftsmanship is marked by clean lines and seamless form. Such vessels constituted a major part of the Rabha community's daily life in a culture where natural resources such as wood and bamboo formed the mainstay of creating durable tools. Now preserved in the Indian Museum, Kolkata, it stands as a functional relic of tribal life and traditional sustainability.
