This is the traditional wooden mortar called Rosom used by the Reang Tribe of Tripura. This is a great sample of indigenous utility and craftsmanship. Now this object has been included in the collection of the Indian Museum, Kolkata. It has been carved out of a single, solid piece of wood, thereby displaying the complete skill of tribal artisans. This is a beautiful and functional structure: a flat circular bottom supports it, while the upper portion features a large conical groove into which food items like rice, lentils, and spices are ground.
The constriction of the midsection looks like two bowls joined at the base but, in reality, provides the grip and steadiness while being used. This design will thus pound effectively, while allowing one or two people to manipulate it with a pestle (Rono). The Rosom is a cooking appliance in the Reang households, but above all, it forms a very important vehicle for community-based preparation of food during festivals and rituals. Sourcing from sustainably managed forests and techniques of hand carving indicate the tribe's level of environmental concerns and the in-depth knowledge systems tradition. It symbolizes the state of self-dependence, harmony with nature, and continuity of culture in the daily lives of the Reang people.
