Ranging from yellow, to gray, to traditional red and orange, bricks are ubiquitous in many of our cities and widely used in construction. Briefly, the manufacturing process of traditional bricks involves molding clay and firing it in ovens, facilitating the creation of solid blocks, perforated blocks, cobogós, tiles, and other shapes. Ceramic bricks are inexpensive; easy to find; boast strong resistance, thermal inertia, and finish; and do not require such specialized labor for construction. But if the installation is done near sources of high heat, the common brick will end up cracking and breaking, making refractory bricks more suitable. But what does that mean?
