Black and Brown Refractory Bricks
Black and brown refractory bricks are produced by adding new mineral compounds to refractory clay. After being fired in the kiln, these bricks develop a color spectrum ranging from black to brown, adding a distinctive touch to building facades. Whether used as a solid color or in a mixed, random arrangement, these bricks create a unique and elegant appearance in both modern and classic facades.
At Rezvan, this kind of bricks are categorized into three types: light brown, dark brown, and black. All of these bricks are produced in the same kiln, with the final color determined by the level of heat they endure. The higher the temperature, the darker the bricks become, approaching a black color. A notable feature of this refractory bricks is that no artificial colorants are used; their natural color results from the firing process and the combination of clay and heat. Due to the presence of mineral salts, slight natural color variations can be seen in these bricks, enhancing their visual appeal.
