Rock Creek Naborigama
At the Canton Clay Works, our unique Naborigama (designed by renowned kiln designer Will Ruggles) has been fired over 250 in the past 15 years, making it one of the most frequently fired wood kilns in the USA. For 24-30 hours the kilns numerous chambers are stoked with wood every 3-5 minutes. The pots in the first chamber are fired in a reduction atmosphere resulting in deep, rich color tone in the clay body, decorative slips, and glazes. The second chamber is considered a Soda Chamber, volatilized with 12 pounds of a salt and sodium mixture, resulting in an atmosphere saturated with vapor that bonds with the silica contained in the clay body, creating a one of a kind sodium silicate glaze.
Climbing Train Kiln
Recently added to our kiln yard is our new Train Kiln (100+ cubic feet), a contemporary rendition of an ancient Anagama (tunnel or tube kiln). This new design was introduced to the U.S. by John Neely of Utah State University, after a trip to Japan. A unique feature of this design is the fire box, known as a burry box, with an unusual stepped grate system on the bottom of the burry box. This is an exceptionally efficient wood-fired kiln that fires faster, with great fuel efficiency resulting in similar results of an Anagama in far less time and energy.
North Carolina’s internationally renowned potter, Judith Duff has made a wonderful CAD program of her kiln based on John Neely’s design. It is from this design that I had made a few unique adaptations: a dramatic increase in size, three Hikidashi ports (means: “to open and pull out), a step in elevation in the large ware chamber (making this a Climbing Train Kiln), the addition of five brick arches, and the unusual hoistable insulated steel center arch, allowing for an aging potter to stand while loading and unloading. Our newly added Climbing Train Kiln’s construction was completed in Early June 2017.

Supporting my eclectic interest in numerous firing techniques, I have designed and built several varieties of kilns that are used frequently.
