The Olympic Kilns GF514E: Ultimate Precision and Space for Glass Firing

Master Large-Scale Glass Projects with Dual-Loading Flexibility and Advanced Heating Control

The Olympic Kilns GF514E is a high-performance kiln designed for glass artists who need space, precision, and control to bring their creative visions to life. With its expansive 29″ wide x 29″ deep by 13.5″ high square firing chamber, the GF514E provides more room than traditional cylindrical kilns, making it ideal for larger projects or multiple pieces. Whether you're working on intricate multi-layer fusions or large-scale glasswork, this kiln offers the perfect balance of size and function for your studio.

Precision Heating for Consistent, Flawless Results

At the heart of the GF514E’s exceptional performance is its advanced dual-element heating system. The lid element delivers radiant heat where it’s needed most—during the fusing stage—while the wall elements provide consistent conductive heat throughout the firing process. This even heat distribution ensures uniform results across your entire piece, minimizing cold spots and imperfections. With a maximum temperature of 1700°F, the GF514E handles a wide range of glass techniques, from simple slumping to complex fusions.

Built to Last with User-Friendly Design

Durability meets functionality in the GF514E. Constructed with a strong stainless steel jacket and supported by an 18” metal stand, this kiln is built for long-lasting performance in even the busiest studios. The lid lift assist makes opening and closing the kiln effortless, even when working with heavier projects. Whether you're a professional glass artist or just starting, this kiln is designed to make your work easier and more efficient.

Easy Control with the Standard KilnStar Controller

The Olympic GF514E comes standard with the Digital KilnStar controller, offering easy-to-use precision control over your firing process. The KilnStar controller simplifies programming with straightforward settings for ramp/hold, ensuring accurate and repeatable results with every use. For those who seek advanced control features, the kiln offers an upgrade option to the Genesis touchscreen controller, which includes expanded programming options such as delay start, preheat, and cone offset for a truly customized firing experience.

Flexible Loading Options for Every Project

The GF514E offers versatile loading configurations to accommodate any artistic need. While the standard top-loading design is perfect for most projects, you can also opt for a dual-loading option that combines top-loading and clamshell functionality. This combination allows for easy glass raking, flash venting, and seamless loading of shelves, providing even greater flexibility and control over your firing process.

Customizable Options for Enhanced Performance

For artists looking to customize their kiln, the GF514E offers a range of optional upgrades. Beyond the upgrade option to the Genesis touchscreen controller for advanced control features, you can add a flash arm for quick venting and quartz glass viewing windows for real-time monitoring of your project. These enhancements allow you to tailor your kiln to your specific needs, ensuring optimal performance for every firing.

Optimize Your Studio with a Custom Furniture Kit

Maximize your kiln’s potential with a custom furniture kit designed to fit the GF514E. The kit includes two layers of shelving, assorted square posts, and ceramic paper to ensure that your glass pieces are evenly supported and heated throughout the firing process. Choose the standard kit or customize your own to suit your unique workflow and project requirements.

The Olympic Kilns GF514E is the ultimate kiln for glass artists who demand precision, space, and flexibility. Its advanced heating system, spacious design, and customizable features make it the perfect tool to elevate your glasswork and achieve consistently stunning results. Unlock your creative potential with the GF514E, and take your glass artistry to new heights.

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.)
