Pearl-22 Glass Fusing Kiln

Includes lid safety switch which turns off power to the heating elements when the lid is raised. The controller remains powered. The switch turns the power to the elements back on when the lid is closed.

The Pearl-22 top lifts away to give access to the shelf area. Air pistons assist in lifting the top. You can place the Pearl on a table without an extra stand.

“You can compose directly on the kiln shelf, then close the kiln top,” said glass artist Judith Conway, who uses the Pearl-18 in her Washington, DC studio. “There is no need to balance and carry a heavy kiln shelf from your work table over to your kiln, trying to load the shelf in the kiln while not disturbing the glass pieces in your design.”

The elements in the top are mounted in pinless element grooves. Since the groove opening is narrower than the element coil, the elements stay in place without pins.

Electrical components are mounted inside the base of the kilns. The Pearl-22 uses the digital 12-key Sentry 2.0 controller.

You will be amazed at the convenience of digital firing. The reliable solid-state Sentry controller continually monitors the firing so you can spend your time productively without closely watching the kiln. (Please remember, however, to check the kiln during firing and to monitor it near the expected shutoff time.) The sealed touch pad keeps out dust and is easy to wipe clean.

The controller has powerful features that you will enjoy using. Yet we have also worked hard to make the controller user-friendly.

Do you ever wonder how much electricity your kiln uses? The digital controller can figure this for you with the press of a button. Find out how little a kiln actually costs to fire. Learn to conserve energy by experimenting with firing speed, load density, etc.
