Pottery kilns are structures for firing pottery. The fired pottery's appearance is influenced by the design and fuel source of the kiln. Certain kilns are limited to what Kiln Atmosphere can be used.
Kiln Types
Electric
Fires in a neutral atmosphere
Reduction is possible by injecting CO2 or adding charcoal, but this damages the elements in the long term
Gas Downdraft
Efficient natural gas or propane powered kiln
Depending on design, can fire very evenly
Can be fired in either oxidation or reduction atmosphere
Train Kiln
Large, horizontal wood fired kiln
Does this fire efficiently? How does it disperse the wood ash?
Noborigama
Multi-chambered wood kiln (name means rising kiln or climbing kiln because it slopes upwards)
The flame can be moved upwards by adding wood to the later chambers, effectively firing the kiln in sections
Fires efficiently
Dragon Kilns take this idea to its logical extreme, fires tens of thousands of pieces at a time
Anagama
Inefficient wood fired kiln
Used to produce pots that are asymmetrically covered in wood ash
Analogous to soda firing, which can create directionality when soda is sprayed
