Clay brick is a building material made from natural clay that is shaped and then fired in a kiln. This process hardens the clay, making it durable and suitable for construction. Clay bricks are known for their strength, thermal insulation, and resistance to fire, making them a popular choice for walls, pavements, and other structures. The use of clay bricks dates back thousands of years, with ancient civilizations like the Mesopotamians and Egyptians utilizing them in their architecture. Today, they are available in various colors and sizes, allowing for versatility in design and construction projects.
