Bricks sit on extruded bars and are placed in rows where they are dried in the heavily regulated climate. 5. Firing. The next major step in making bricks is the firing process. Generally, bricks will stay on the same cars used for the drying process to take them into the kiln. This is where firing takes place.
The term brick refers to small units of building material, often made from fired clay and secured with mortar, a bonding agent comprising of cement, sand, and water. Long a popular material, brick retains heat, with-stands corrosion, and resists fire. Because each unit is small—usually four inches wide and twice as long, brick is an ideal ...
