Using 21” diameter kiln shelves, these models are perfect for the serious home studio, or schools. They all draw less than 50 amps on a household 240 volt circuit, yet are big enough to fire26 cups* per shelf, and capable of firing to cone 10. In floor A1 heating elements, and multi-zone temperature control come standard on all three models, ensuring perfectly even firings from top to bottom. Double wall design incorporating 1” of block insulation backing up the 2.5” bricks means a cooler exterior, and a 32% energy savings over other brands that just use 2.5” bricks. The patented Tucker’s Cone Art Lid Lifter comes standard on all 3 models, and you can choose either the V6-CF or Genesis touch screen controller. A Safety Lid Switch, and Integrated Vent system are available options. The 2327D is our most popular kiln as it is the largest kiln you’d typically find in a home while also being a perfect choice for schools, and even small production studios.
