Bricks are made from local clays and shales extracted and processed for manufacturing. The raw material undergoes crushing, grinding, and screening to achieve fine consistency. This refined material is then mixed with water to create a pliable clay mixture ready for shaping into bricks through various forming processes.

The soft mud process shapes clay with high moisture content in molds, producing water-struck or sand-struck bricks with smooth or matte textures. The dry press method uses minimal water content under high pressure, suitable for clays that shrink excessively. The stiff mud process, the most common and cost-effective, extrudes clay with moderate water content through a die, allowing surface textures or color applications.

Kiln temperatures between 1800 and 2400 degrees Fahrenheit directly influence brick size and color. Higher temperatures cause greater shrinkage and produce darker bricks. The firing duration ranges from 40 to 150 hours, and controlled cooling measures are implemented afterward to prevent thermal cracking in the finished bricks.

After shaping, bricks are air dried to remove moisture before entering the kiln. This drying phase prepares the clay units for the high-temperature firing process. Once dried, bricks are exposed to controlled heating in kilns, which solidifies them and prepares them for construction use.

The stiff mud process is the most common and cost-effective brick manufacturing method because it uses clay with moderate water content extruded through a die. This approach allows for efficient production while offering flexibility for surface textures or color applications. It balances production efficiency with the ability to create varied brick designs.

Water-struck and sand-struck bricks are both produced using the soft mud process but differ based on mold preparation. Water-struck bricks result in a smooth texture, while sand-struck bricks have a matte texture. The choice of mold preparation method determines the final surface finish and aesthetic qualities of the brick.

Controlled cooling measures are implemented after kiln firing to prevent thermal cracking in bricks. Rapid temperature changes can cause stress and fractures in the fired clay units. Gradual, controlled cooling ensures the bricks maintain their structural integrity and brick durability strength and appearance for construction applications.
