Olympic Kilns Square 189GFE: Precision Firing for Stunning Results

Master the Art of Glass Fusing with Unmatched Control and Flexibility

Introducing the Olympic Kilns Square 189GFE, a top-loading kiln designed to bring your glass fusing and forming projects to life with precision and ease. With a spacious 18″ wide x 18″ deep by 9″ high firing chamber, this kiln offers the ideal environment for artists who demand consistency and reliability in their work. Whether you’re fusing intricate glass designs or heat-treating delicate pieces, the Square 189GFE provides the advanced features and user-friendly controls you need to achieve flawless results every time.

Superior Heating for Every Stage of Your Process

The Square 189GFE is equipped with both lid and body elements, providing complete control over every stage of the glass firing process. The lid element is perfect for achieving the intense, even heat required during the fusing segment, while the body elements ensure a smooth ramp-up and annealing phase. With the Digital KilnStar controller, you can precisely program and adjust the heating profiles to suit your specific project needs, whether you require rapid heating for high-intensity tasks or a more controlled heat distribution for delicate work.

Built for Durability and Ease of Use

Constructed with a stainless steel jacket and supported by an 18” tall metal stand, the Square 189GFE is built to withstand the demands of frequent use in a professional studio environment. The kiln’s top-loading design makes it easy to access your work, and for those seeking even more versatility, an upgrade to a combination top-loading and clamshell lid design is available. This innovative design allows you to open the kiln like a clamshell, providing effortless access to your projects and making it ideal for larger or more delicate pieces that require careful handling.

At the heart of the Square 189GFE is the standard Digital KilnStar controller, a powerful yet user-friendly interface that ensures every firing is precise and repeatable. The KilnStar controller offers advanced programming capabilities with multiple programmable segments, allowing you to create complex firing schedules tailored to your unique projects. Its intuitive controls make it easy to set ramp rates, target temperatures, and hold times, giving you unparalleled control over your firing process. With features like delay start, preheat, and skip-step, the KilnStar controller empowers you to achieve consistent, high-quality results, while its reliability lets you focus on your artistry with confidence.

For those who desire even more control and convenience, an upgrade to the Genesis Touchscreen controller is available. The Genesis controller brings all the functionality of the KilnStar controller to a full-color touchscreen interface, making it even easier to program complex firing sequences. With graphical displays, real-time temperature graphs, and intuitive navigation, the Genesis controller enhances your kiln experience. It also offers additional features such as built-in help resources, Wi-Fi connectivity for software updates, and the ability to store and recall an expanded number of firing programs. The Genesis controller is designed to streamline your workflow and provide an even more seamless firing experience.

Customization and Upgrades for Enhanced Performance

The Square 189GFE is as versatile as you are, with a range of optional upgrades available to enhance its performance. In addition to the Genesis Touchscreen controller and the combination top-loading and clamshell lid design, you can also opt for features like a lid lift assist for effortless operation, a quartz glass viewing window for real-time monitoring, and an automatic lid shutoff that immediately turns off power to the heating elements the moment the kiln door is opened.

If interested in either (or both) the 480-volt option and 3-phase wiring configuration (at any voltage), contact Pottery Pulse directly to get details and pricing information.

Optimize Your Workspace with a Furniture Kit

To make the most of your kiln’s capacity, consider adding a furniture kit designed specifically for the Square 189GFE. The kit includes two layers of shelving, assorted square posts, and ceramic paper, ensuring that your glass pieces are evenly supported and heated during firing. Choose the standard kit or customize your own to fit your unique workflow and project requirements.

Its exceptional features, flexibility, and durable construction make it an ideal choice for artists looking to take their craft to the next level.

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.)
