Many of our larger electric kilns have electrical requirements beyond what is commonly found in private homes. Before purchasing, please confirm the electrical requirements of the kiln and the electrical availability in the space where you will be using the kiln. We recommend consulting an electrician!

The perfect kiln for professional studios and schools, our eight-sided 18" Top-Loading Professional-Grade Electric Pottery Kiln offers potters considerably more interior space than our 12" Pottery Kiln, but still fits well in home studios.

Our favorite features for the 18" Pottery Kiln are:

  • Sized right for easy loading and unloading
  • 18” interior diameter
  • Fires to Cone 10
  • Includes a V6CF digital controller
  • Available in two heights (all measure 18” as the interior diameter): the 18” interior depth model has 2 rings and is approximately 2.8 cubic feet; the 27” interior depth model has 3 rings and is 4 cubic feet

  • We can accommodate most electrical customization. Please contact us if you need 3-phase power or have other electrical requirements

18" deep model require a minimum 30 Amp breaker and NEMA 10-30 plug. 27" deep model requires a minimum 40 amp breaker and NEMA 6-50 plug.

For home studios, we recommend the 18” Top-Loading Home Pottery Studio Kiln which has 2 rings and requires only a 30 Amp breaker. Beware of any kiln rated for more than 30 amps if you want to avoid hiring an electrician to rewire your home studio.
