How Are Building Bricks Made?
Bricks are made out of clay. Any kind of clay can make reasonably good bricks. Bricks are made in factories which are less complex in nature. Not a lot of machinery is required to manufacture bricks. Dug out clay is mixed well with water. The mixture is well grounded to obtain a texture which will allow the shaping of clay into a brick. Portions of this mixture are then shaped like bricks and are set out to dry. Drying is a slow process and can take days. When bricks are naturally dried out in the sun, they are a green color. The bricks are then fired or baked in an oven at the temperatures between 1000 to 12000 degrees; this is done so that all the excess water from the bricks is dried out. This is how bricks take on their famous red colour.
