Why are the bricks heated in a kiln?

Green bricks are fired in the kilns to convert a fairly loosely compacted blend of different minerals into a strong, hard, and stable product i.e. fired brick. Depending on nature of clay and quality of fired brick requirement, bricks are fired in a temperature range of 800–1100oC.

Who invented the kiln?
