Chinaware bricks are a type of sintered bricks, primarily made from clay. After the clay is mixed with water, it is extruded into shape and then fired in a kiln at approximately 1000 degrees Celsius. The bricks are cooled with water to prevent the iron in the clay from oxidizing completely, enhancing their resistance to weathering and water. Tests show that ancient chinaware bricks have a compressive strength exceeding 10 MPa and a water absorption rate of less than 20%.仿古青砖 are replicas of ancient chinaware bricks, following the same firing methods and using the same clay material as the ancient bricks, but produced with modern techniques.
