Fire Bricks

Fire bricks are used in construction to ensure that there is no chance of a fire breaking out. These bricks are made of clay and coated with a material called bitumen. They are then left to dry in the sun, before they are finally fired in a kiln. The process of firing them causes the bitumen to melt and bond with the clay, creating a fire-resistant material that can withstand temperatures of up to 2000 degrees Fahrenheit.
