Different Types of Kiln Construction
Before delving into specifics, it's important to recognize that there are two basic types of kilns: continuous (tunnel) kilns and periodic (intermittent) kilns. Continuous kilns are always firing, so they never cool. The ware to be fired is loaded into cars and slowly goes through the kiln on a track or rail.
