tunnel kiln
Quick Summary
A tunnel kiln is a type of continuous kiln used in pottery and other ceramic manufacturing processes. In a tunnel kiln, wares are conveyed slowly through different temperature zones, moving from a cooler entrance area to the hottest part in the center, and then gradually cooling as they approach the exit. This design is more economical and efficient than older intermittent kilns, which required complete cooling between firing cycles. Tunnel kilns allow for a steady production flow, with the material entering at one end and the finished product emerging from the other.12
