Local people in villages still store yoghurt, milk and ghee in theki, the traditional wooden vessel, locally made from daar tree (Boehmeria rugulosa). Other similar vessel with wide opening is called faam which is especially designed to keep milk while milking.
Size of the these vessels is varied. Smaller one which store up to 1 pathi (4.57 liters) of liquid is called theki while bigger one which store up to 4 pathi is called theka. These vessels are made by local technicians in the locally designed water mill. The downward flow of water rotates the turbine blades which then rotate the shaft connected to it. The theki is attached to other end of the shaft. It takes some 3 hours to make a theki.
