The three essential components in a pottery kiln are: (1) a fire-chamber with one or more fire-places, where fuel is burnt in a continuous supply of air; (2) vents to transfer the hot gases generated in the fire-chamber into the baking chamber; (3) a baking chamber which is an enclosed space, like an oven, where the sun-dried clay objects are carefully stacked and heated to the required temperature. Depending upon how the draught of hot gases moves within the baking chamber, the pottery kilns are called: (1) vertical up-draught kiln, (2) vertical down-draught kiln, and (3) horizontal kiln.
