The NEW ProFusion 26 is the latest Jen-Ken innovation. It has a HUGE 26x26 opening. It comes on an integrated stand with casters, has a spring assisted lid and has quartz encased elements. The top is 2300 degree rigid fiber, and allows for quick firings. The kiln comes standard with a ceramic shelf. You can fire as fast as 500 degrees an hour. Optional is an FIBER shelf, which makes it an all fiber firing chamber, and allows you to fire small pieces even more quickly. The Orton 12 key controller is very easy to program and use, and features Skip Step, Add Time, and Add Temperature with the push of a button. It comes with a two year warranty.
