But what about the firing performance, you ask? Cone Art Kilns have been designed to withstand the high demands of the production potter or school. In addition to high efficiency insulation, Cone Art only uses thick-gauge, high quality Kanthal A1 element wire in their kilns. This makes firing to cone 10 a breeze even with high mass loads. The elements are spaced in the kiln in such a way to take advantage of the natural heat-flow within a kiln, with wide element channels to keep the elements from overheating. Floor elements help keep the firings even from the center of the kiln to the outside wall, while the standard multi-zone Bartlett controller helps keep the kiln firing even from bottom-to-top.
