Bricks

Bricks, a fundamental building material, are crafted from fired clay and exhibit a range of shapes, sizes, and colors. The production process starts with extracting local clay or shale, which is then crushed, ground, and screened for a fine texture. The refined material is blended with water, creating a pliable mixture that can be formed into bricks using one of three processes: soft mud, dry press, or stiff mud methods.
Soft mud bricks are shaped in molds with high moisture content and can be...
