POTTERY KILN

Pottery kiln is a device that can efficiently fire green pottery wares at the high temperature required for vitrification. The green sun dried pottery wares are loaded in the pottery kiln and fired for about 8 hours. Traditionally green pottery wares are fired in conventional pottery kilns that are just dug out spaces in the ground.

The fuel efficient pottery kiln consists of two chambers. The insulated lower chamber which is the combustion chamber is about a third of the volume of the upper chamber where the wares are stacked. Arched brick structures that allow hot gases to pass through them separate the two chambers. The top of the kiln is open and plastered with mud plaster after the wares are loaded.

Depending on the size and the shape of the wares the firing time is between 8-10 hours.
