In this technique of painting on rounded wooden surfaces, lac is applied onto the surface of wood using friction-generated heat created by the rotatory movement of a lathe or kharand. Shellac or purified lac are used as bases into which mineral colour pigments are mixed and moulded into cubes of coloured lac called battis. The surface of the wooden object is first smoothened so that cracks and pores may be filled in. A batti of the required colour is pressed onto it while it revolves on the lathe. The heat generated as a consequence causes the lac to melt and spread over the wooden object. When the colour is uniformly coated all over, rag dipped in oil of kevda leaves (Pandanns odoratissimus) dipped in groundnut oil is pressed against the turning object so as to polish the lac till it acquires a permanent shine.
