Maximize Your Glass Firing Space with the Olympic Kilns GF5E Glass Firing Kiln

Achieve Flawless Results with Precision and Space in One Kiln

Step into a new era of glass artistry with the Olympic Kilns GF5E, a kiln that offers expansive firing space and precision, perfect for glass fusing, slumping, and complex, multi-layered creations. With its impressive 29″ wide x 29″ deep by 9″ high firing chamber, the GF5E is designed for artists who require room to bring intricate designs to life. This square kiln provides significantly more space than traditional cylindrical models, making it ideal for large-scale projects or handling multiple pieces at once.

Advanced Heating System for Consistent, Even Firing

The GF5E is equipped with a sophisticated dual-element heating system that ensures even and consistent heat distribution throughout every firing. The lid houses a radiant heat element, delivering the intense heat necessary for achieving perfect fusing temperatures, while conductive elements embedded in the walls provide uniform heat, minimizing the risk of cold spots. This advanced system allows the kiln to maintain a maximum temperature of 1700°F, making it versatile enough for a wide range of glass techniques, from simple slumping to intricate fusions.

Durability and Ease of Use for Busy Studios

Designed for longevity, the GF5E is constructed with a durable stainless steel jacket and stands on a sturdy 18” tall metal base, making it reliable for everyday use in busy studios. Its lid lift assist feature makes it easy to open and close the kiln, even when working on larger, heavier projects.

The kiln comes standard with the Digital KilnStar controller, which provides intuitive, user-friendly control over firing schedules, allowing for precise adjustments to ramp/hold settings. This ensures accurate, repeatable results with every use. For those looking for even more control, the Genesis touchscreen controller is available as an upgrade, offering advanced programming features like delay start, preheat, and skip step for added flexibility.

Versatile Loading Options for Every Artistic Need

The GF5E offers versatility in loading configurations, available as a standard top-loading kiln or customizable with a combination of top-loading and clamshell design. This flexibility allows for easy flash venting, precise glass raking, and effortless loading of shelves. Whether you're working on large fused glass pieces or exploring new techniques, this kiln meets the demands of even the most intricate projects.

Customize Your Kiln for Enhanced Performance

The GF5E offers a range of customizable upgrades to suit your specific firing needs. In addition to choosing the Genesis touchscreen controller for advanced programming, you can consider adding features like a flash arm for quick venting, automatic lid shutoff to power down when the lid opens, or quartz glass viewing windows for real-time project monitoring. These upgrades allow you to tailor your kiln to your exact requirements, ensuring optimal performance and ease of use.

Optimize Your Studio with a Custom Furniture Kit

Maximize the efficiency of your GF5E with a dedicated furniture kit, designed to support your glass pieces during firing. The kit includes two layers of shelving for efficient stacking, along with assorted square posts and ceramic paper to ensure even heating and support. Whether you opt for the standard kit or customize your own, these accessories enhance your kiln’s functionality and help maintain a well-organized studio environment.

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.)
