Bricks and brickwork

Introduction Originally, bricks were hand-moulded frommoist clay and then sun-baked, as is still the practice in certain arid climates. The firing of clay bricks dates back well over 5000 years, and is now a sophisticated and highly controlled manufacturing process; yet the principle of burning clay, to convert it from its natural plastic state

into a dimensionally stable, durable, low-maintenance ceramic material, remains unchanged.
