The Olympic Kilns GF314E: Superior Space and Precision for Glass Firing

Unlock New Possibilities in Glass Art with Spacious Design and Advanced Heating Control

Elevate your glass art with the Olympic Kilns GF314E, a kiln built to provide the space and precision needed for your most ambitious projects. With its square 25" W x 25" deep by 13.5" high firing chamber, the GF314E offers significantly more room than traditional cylindrical kilns, making it perfect for large-scale fusions, intricate layered works, and detailed projects that demand space to thrive.

Precision Heating for Consistent, Flawless Results

The GF314E is designed with a dual-element heating system that combines radiant and conductive heat, ensuring even temperature distribution throughout the firing chamber. The lid element delivers concentrated heat exactly when needed, particularly during the critical fusing stage, while the wall elements maintain a steady, uniform temperature. With a maximum temperature of 1700°F, this kiln is ideal for various glass techniques, including slumping, draping, and full fusing, minimizing the risks of uneven heating or cold spots.

Durability Meets Ease of Use

Built for both performance and convenience, the GF314E features a durable stainless steel jacket and a solid 18” metal stand, ready to meet the demands of a busy studio. The kiln comes standard with a lid lift assist, making it simple to open and close, even when working with larger or heavier pieces. Equipped with the Digital KilnStar controller, the GF314E allows you to easily set and monitor firing schedules, giving you reliable, repeatable results every time.

Versatile Loading Options for Creative Flexibility

The GF314E offers versatile loading configurations to suit your artistic needs. Choose the standard top-loading design or opt for a combination of top-loading and clamshell design for easier access to your projects and to accommodate different glass shapes and sizes.

Upgrade Your Control with the Genesis Touchscreen

For those who want more advanced control over the firing process, you can upgrade to the Genesis touchscreen controller. This intuitive control system offers advanced programming features like delay start, preheat, and skip-step, allowing you to fine-tune your firings for exceptional precision and artistic freedom.

Tailored Accessories for Optimal Efficiency

Complete your studio setup with a custom furniture kit designed specifically for the GF314E. This kit includes two layers of shelving, assorted square posts and ceramic paper to ensure your glass pieces are evenly supported and perfectly heated during each firing. You can choose the standard kit or customize it to meet your unique needs.

The Olympic Kilns GF314E is your key to unlocking greater creative possibilities. With its generous space, precise heating capabilities, and customizable options, this kiln is the perfect companion for artists looking to push the boundaries of their glass artistry.

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.)
