Base on the use of fuels, the most common kilns for studio potters are electric kiln, gas kiln and wood kiln.
Electric Kiln is requires no chimney or fuel lines. The combustion room is ether below or to the one side of the kiln chamber. Electric kiln uses electricity to power installed elements for heating. Kiln elements are made of high temperature wire such as Kanthal AI that can go up to 1400C. The kiln temperature is controlled by a kiln controller or dial from low, medium and high range. It is portable, simple and safe to operate, which is convenient for the studios, school and community setting. Most electric kiln needs only 220-volt electrical outlet. That is easier to set up and install. It usually comes with top loader (top door opening) or front loader (front door opening).
Gas Kiln become very common when both natural gas and propane are readily accesable.
Wood kiln requires a bigger room with a grate and an ash pit.
Saggers are used to packed the glazed pots from falling ash.
