Create Large Panels and Deep Castings with the GTS 41 Studio Kiln
If you’re working on oversized panels, deep slumps, or stacked castings, the Evenheat GTS 41 Glass Kiln gives you the space and power to do it right. With a generous 25.25" x 40.5" x 13.5" interior (7.52 cubic feet), it’s designed for firing large glass sheets, tall molds, or multiple projects in a single load. The kiln fires up to 1800°F, giving you the range needed to fuse, slump, and cast heavy-duty glass.
Full firebrick construction helps heat move evenly through the chamber, so big pieces don’t crack at the edges or bubble in the middle. The Quiet Drive solid-state relays keep your temperature stable and quiet while protecting your elements over time. Whether you’re layering thick builds or running production trays, you can count on this kiln to finish clean and fire smoothly.
You can mount it on a bench or pair it with a rolling stand for easier access. The Swing View control panel tilts so you can check temps without bending over, and the two-position lid vent gives you better control of your cooling cycle. For big ideas and big firings, this kiln gives you the room to make it happen.
