Fire Round Panels, Deep Slumps, and Glasswork with the GTS 23 Studio Kiln
The Evenheat GTS 23 Kiln gives you room to fire wide glass plates, tall slump molds, full panel work, and casting projects—without crowding your load. The 23.5″ diameter chamber and 13.5″ depth offer 3.5 cubic feet of workspace, giving you the flexibility to fire large single pieces or multiple smaller forms with even spacing and airflow.
The all-firebrick construction holds and distributes heat evenly across every inch of the chamber. That means cleaner annealing, better edge-to-center consistency, and fewer firing surprises. Whether you're layering sheets, firing thick sections, or working with drop molds, this kiln is built to support the detail and precision your work demands.
Evenheat includes the Quiet Drive solid-state relays for smooth, accurate temperature control that protects your elements over time. The Swing View panel lets you program comfortably from any height, while the two-position lid vent gives you better control over cool-down speed and burnout. And when it’s time for maintenance, the relay access port saves you from digging into panels or calling for help. The GTS 23 is a reliable studio tool—designed to handle demanding glass work, day after day.
