Brick can be manufactured in many ways to give unique appearances. The different processes may be characterized as red bodied with textured or sand faces, ad-mix or thru-body, wood moulded or hand-made, and thin brick. Brick are made from clay, shale, sand, water and other additives. The process of manufacturing involves mining the clay/shale, grinding, pressing into a green form, adding coloring, drying, firing to 2000+ degrees Fahrenheit, and then packaging. Most brick deliveries are by truck, thought some go by rail for longer distances.
