Master Large Glass Projects with the Olympic 309GFE: Built for Big Ideas and Unique Shapes

The Olympic Kilns 309GFE is crafted to meet the needs of glass artists working on large or unusually shaped pieces. With an expansive firing chamber measuring 42″ wide by 30″ front-to-back by 9” deep, this oval kiln is designed to handle oversized glass fusing, forming, and heat-treating projects that don’t fit in standard cylindrical or square kilns. Whether you’re creating intricate designs or tackling large-scale projects, the 309GFE offers the space and flexibility you need to achieve outstanding results.

Advanced Heating Control for Consistent Quality

The 309GFE is equipped with heating elements in both the lid and the body of the kiln, ensuring even and precise heat distribution. The lid element provides focused radiant heat necessary for the fusing stage, while the body elements handle the ramping up, cooling down, and annealing processes. An infinite switch allows full control over the lid element’s intensity, enabling you to adjust heat levels to meet the specific needs of each project. This flexibility ensures uniform heating, reducing the risk of defects and ensuring high-quality outcomes.

Built for Durability and Ease of Use

Constructed with a durable stainless-steel jacket and supported by an 18″ tall metal stand, the 309GFE is designed for longevity and ease of use in any studio environment. The kiln comes standard with the Digital KilnStar controller, providing precise control over firing schedules with easy programming for ramp-hold cycles. The KilnStar controller’s intuitive interface makes it simple for artists to customize their firing processes, ensuring reliable, repeatable results.

For those seeking more advanced features, the Genesis touchscreen controller is available as an upgrade. The Genesis offers an intuitive, modern interface with expanded programming capabilities, giving you even more control and flexibility for your firing cycles.

Customizable Options for Enhanced Performance

The 309GFE offers a range of optional upgrades to further enhance its performance. Whether you’re interested in adding a bead door, quartz glass viewing window, or an automatic lid shutoff, these options provide additional control and customization to suit your specific needs. The kiln can be tailored to your unique studio setup, ensuring it meets the demands of your creative projects.

Optimize Your Kiln with Tailored Furniture Kits

Complete your kiln setup with a custom furniture kit designed to support your firing needs. The 309GFE furniture kit includes two layers of shelving for stacking pieces, along with square posts and ceramic paper to ensure even support and heating throughout the firing process. You can choose the standard kit or build your own to create the perfect setup for your specific projects.

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.)
