TUNNEL KILN
ca: FORN DE TÚNEL
es: HORNO DE TÚNEL
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 the ware 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 the ware leaves the kiln at room temperature.
