Whether you’re working on large-scale glass panels, intricate designs, or expansive installations, the GF15E provides the expansive workspace and power necessary to achieve flawless results.

Engineered for Endurance and Superior Performance

Built with a robust frame of angle iron and metal tubing, the GF15E is designed to withstand the most rigorous use. The kiln's 4 ½” thick insulating brick walls are layered with 1” ceramic fiberboard and an additional 1” air space, creating a highly efficient insulation system that ensures consistent internal temperatures while keeping the exterior cool. The double-insulated floors, constructed from brick and ceramic fiberboard, further optimize heat retention and energy efficiency, making the GF15E an excellent choice for continuous, high-capacity production.

Flexible Loading Options to Suit Any Project

The GF15E offers multiple loading configurations to meet a wide range of project requirements. It can be customized as a top-loading kiln, a clamshell-loading kiln, or a combination of both, offering the flexibility to accommodate various glass shapes and sizes.

Precision Control with Advanced Customization

Equipped with the Bartlett KilnStar digital electronic controller, the GF15E provides precise control over the entire firing process. For those who require even more customization, optional upgrades such as the Genesis touchscreen controller and multi-zone control offer enhanced accuracy and flexibility. The kiln’s heavy gauge elements and industrial relays are built for long-lasting performance, while safety features like a hinged electrical box, breaker box, pilot light, and optional automatic lid shutoff ensure safe and reliable operation.

Maximize Your Kiln's Potential with Custom Accessories

The GF15E can be further optimized with a wide range of optional accessories, including lid elements in quartz rods, 480-volt power options, and advanced venting systems. For detailed specifications and pricing on the 480V option, contact Pottery Pulse, where we can help you customize your kiln to meet your specific production needs.

Additionally, the GF15E is compatible with furniture kits designed to enhance its performance. These kits include ceramic fiberboard shelves, ceramic paper, and large square posts, ensuring even heating and support for your glass projects during firing. Whether you choose the standard kit or opt to build your own, these accessories will help you maintain a well-organized and efficient workspace tailored to your artistic needs.

The Olympic Kilns GF15E is revolutionary tool for glass artists aiming to push the boundaries of their creativity. With its unparalleled capacity, robust construction, and advanced features, the GF15E empowers you to take on larger and more ambitious projects, achieving new levels of excellence in your craft.

FAQs - Configuring Your Kiln

There are certain selections you must choose. And then there are options you can click on or ignore. The answers below should help you make the best choices for you.

 Which Kiln Voltage Should I Select?

Higher voltage means lower amperage draw and greater efficiency, which can save money long term. 240V and 208V cost the same—most home studios use 240V, while 208V is common in schools or large facilities. Amperage refers to the amount of electrical current a kiln draws—higher amps require heavier wiring and breakers.

What's The Difference Between Single-Phase and Three-Phase?

Single-phase is what almost all homes have. If your facility has three-phase, you can choose either—but three-phase is typically the better long-term option due to smoother power and improved efficiency.

Which Relay Option Do I Need?

Mechanical relays are standard and reliable. Solid-state relays (SSR) offer silent operation, faster cycling, greater precision, and longer lifespan—ideal for frequent or high-accuracy firings.

What Are The Differences Between Kiln Controllers?

The following controllers are used across kilns sold by Pottery Pulse. Not all models offer every option—available controllers are listed on each product page. Some kilns include only the standard controller, while most allow upgrades for added precision and convenience.

Olympic Kilns

  • Infinite Switch – Manual dial control for simple heat adjustments.
  • KilnStar – Digital controller with preset and user-defined programs.
  • Genesis – Advanced touchscreen interface with Wi-Fi and data logging.

Evenheat Kilns

  • Icon – Digital 3-button controller for straightforward firing.
  • RampMaster II – Manual digital controller for ceramic kilns; flexible ramp/hold programming.
  • RampMaster 3 – Updated version for glass kilns with refined interface.
  • Icon+ – Enhanced digital control with expanded profiles and precision.
  • TAP II – Smart touchscreen controller with Wi-Fi, data tracking, and remote access.

Hot Shot Kilns

  • Novus – “Set & Go” controller: set a target temperature and it does the rest (no segments).
  • Spark – Entry-level touchscreen controller with intuitive operation and limited program control.
  • TAP II – Smart touchscreen controller with Wi-Fi and real-time monitoring.

Jen-Ken Kilns

  • Orton AF3P 3-Button – Reliable and straightforward for basic firing.
  • Orton AutoFire 4000 12-Key – Expanded program capacity and fine control.
  • Orton AutoFire Slide Touchscreen – Modern, responsive touchscreen interface.
  • TAP II Touchscreen Smart Controller – Wi-Fi connectivity and real-time data tracking.

What Are Collars For?

Not all kilns can use a collar, but Olympic’s Hot Box kilns can be ordered with a collar to expand versatility. A blank collar simply adds height to the firing chamber, while a bead collar adds the same height and includes a built-in bead or annealing door for quick-access lampwork projects.

What Does The Power Interrupt Switch Do?

This safety feature automatically cuts power to the heating elements whenever the kiln lid or door is opened. It prevents accidental burns, protects elements, and resumes power only when safely closed. (Also called an automatic lid shutoff on Olympic kilns.)
