Oval kilns are designed for large workloads and unusual shapes that do not fit in a cylindrical or square shape kiln. Olympic Oval models are built with 3″ brick and have a 2″ blank brick row in the first section of the kiln to protect the elements when loading and unloading the kiln.
Oval models are built with the Olympic-proven electrical box design which has heat shields with top and bottom perforations to keep the electrical components cool. Balanced heating elements ensure even heating of the firing chamber under all firing conditions. Oval kilns come equipped with a pilot light, metal stand, stainless steel jacket, lid lift assist, and Bartlett KilnStar digital controller. One-year Limited Kiln Warranty for cone 10 models.
Upgrade to the Genesis touchscreen controller for more ramp-hold user programs and multiple features including delay start, preheat, cone offset, skip step, and many more. Other options include a Type S thermocouple, 480 volts, 2 or 3-zone control, vent, and much more! Furniture kits are available for the oval electric kilns, including three layers of shelving, kiln wash, and large square posts in assorted sizes.
