Olympic Kilns GF3E Glass Firing Kiln

Unlock new possibilities in your glasswork with the Olympic Kilns GF3E, a kiln that redefines glass fusing with its generous 25″ wide x 25″ deep x 9″ high square firing chamber. Unlike traditional cylindrical kilns, the GF3E offers significantly more room for larger pieces or multiple projects, providing the perfect platform for intricate fusions, detailed designs, and layered glasswork. This kiln gives you the freedom and precision to create with confidence and achieve flawless results.

Precision Heating for Even, Consistent Firing
The GF3E is designed for optimal heat distribution with its advanced dual-element system. The lid element delivers intense radiant heat essential for fusing, while the wall elements provide consistent conductive heat throughout the firing chamber. This combination ensures uniform heating across every part of your glass piece, minimizing the risk of cold spots or uneven results. With a maximum temperature of 1700°F, the GF3E is ideal for a wide range of glass techniques, from slumping to complex fusions.

Built to Last with Thoughtful Design
Crafted for durability, the GF3E features a robust stainless steel jacket and an 18” tall metal stand, built to withstand the demands of daily use in a busy studio. The included lid lift assist makes it easy to open and close, even when handling large or heavy projects, ensuring smooth operation with every use.

Easy, Accurate Control with the KilnStar Controller
The Olympic GF3E comes standard with the Digital KilnStar controller, offering precision control over your firing schedules. The KilnStar controller allows easy programming of ramp/hold settings, ensuring your firings are accurate and repeatable. Its intuitive interface makes it accessible for artists of all skill levels, helping you achieve consistent, reliable results for every project. For those seeking even more advanced control, the kiln can be upgraded to the Genesis touchscreen controller, offering expanded features like delay start, preheat, cone offset, and more.

Versatile Loading Options for Every Artistic Need
The GF3E offers versatile loading configurations to suit your artistic requirements. Choose the standard top-loading design, or customize it with a combination top-loading and clamshell design, giving you added flexibility to accommodate various glass shapes and sizes.

Customizable Options
Beyond the option to upgrade the controller to the Genesis touchscreen, additional options include an automatic lid shutoff for safety, flash arms for quick venting, and quartz glass viewing windows for real-time observation of your work during the firing process.

Optimize Your Studio with a Custom Furniture Kit
Enhance the efficiency of your kiln with a custom furniture kit designed specifically for the GF3E. The kit includes two layers of shelving, assorted square posts, and ceramic paper, ensuring that your glass pieces are evenly supported and heated throughout the firing. Whether you choose the standard kit or tailor your own, these accessories help keep your studio organized and productive.

The Olympic Kilns GF3E is more than just a kiln—it's a creative partner that offers the space, precision, and flexibility you need to elevate your glass artistry. With its spacious design, advanced heating control, and customizable features, the GF3E empowers you to take on more ambitious projects and achieve consistently outstanding results.
