Large-Capacity Chamber for Glass Projects with the GTS 28 Studio Kiln
You’ve got deep molds, big panels, and bold ideas—this kiln is ready for all of it. The Evenheat GTS 28 Glass Kiln gives you a spacious 28″ x 28″ x 13.5″ interior, ideal for wide platters, layered glass builds, or multiple molds in a single firing. With firing capability up to 1800°F, you can fuse, slump, and cast thick pieces without stress.
This kiln runs on 240 volts and uses full firebrick construction, which holds heat evenly across the entire chamber. That means your edges finish clean, centers don’t lag behind, and your glass projects come out smooth and consistent. Whether you’re firing a 6-layer art panel or a set of production slumps, this kiln handles it.
The GTS 28 is built with working artists in mind. From the Quiet Drive solid-state relays to the Swing View control panel and two-position lid vent, every detail supports repeat firing with accurate results. Use it in your home studio, school lab, or professional glass shop—it’s built to keep up with you.
