Tunnel kilns are also known as continuous kilns. The ware is put on to bats, the bats are on rollers which turn and slowly move the ware through a long tunnel and as it moves, it goes through the whole process of firing. The heat increases and when it reaches the central section it will be at the hottest part, the heat required for that type of ceramics. It goes on moving, but with the temperature gradually reducing until it leaves the kiln at room temperature.
