Elevate Your Glass Artistry with the Olympic Kilns Square 186GFE

The Epitome of Versatility and Precision in Glass Firing

The Square 186GFE from Olympic Kilns is a masterpiece of kiln design tailor-made for the ambitious glass artist. Choose from THREE different loading configurations: top load only, clamshell lid only, or BOTH! As the largest glass firing kiln available on a 120-volt system, this model boasts a spacious interior of 18" wide x 18" deep x 6" high (volume = 1.125 cubic feet!), and a firing capability up to 1550°F/843°C. It's the perfect fusion of size, power, and innovation, designed for the intricate art of glass fusing, forming, and precious metal clay work.

Dual-Element System for Unmatched Control

The Square 186GFE features a dual-element system, with a lid element dedicated to the fusing segment and a body element for precise control during ramping, annealing, and cooling. The unique selector switch on the electrical box empowers you to choose between the lid or body element, adapting to the specific needs of your project with ease and precision.

A Symphony of Advanced Features

With Olympic Kilns, you're not just buying a kiln; you're investing in an experience. The Square 186GFE comes standard with the Bartlett Digital KilnStar controller, but you can consider an upgrade to the Genesis Touchscreen controller for even more advanced features that add to the precision and convenience of your firing experience. Monitor your firing profile with ease, ensuring exact firings every time.

Customization at Your Fingertips

Make the Square 186GFE uniquely yours with a range of optional enhancements. From the practicality of the lid lift assist and the clarity of a quartz glass viewing window to the convenience of a vent system, your kiln can be tailored to fit your artistic vision.

You might also might want to add lid elements in the quartz rods for glass firing.

Effortless Mobility and Safety

Consider the stand with caster wheels for effortless relocation within your workspace, ensuring your kiln is always in the perfect spot. And for peace of mind, the automatic lid shutoff switch is a must-have, cutting power to the heating elements when the kiln is open and reinstating it upon closure.

You can also add a flash arm, an optional metal arm on the kiln that is notched for 2″ and 4″ openings for the lid venting.

The Ultimate Furniture Kit for Every Artist

The Furniture Kit for the Square 186GFE is a necessity for any serious artist. Including two layers of 16" x16" shelving, assorted square posts (4 each of 1/2, 1, and 2 inch posts), and 3 square feet of ceramic paper; it's designed to maximize your firing space and protect both your kiln and creations.

Innovative Solid State Relay for Efficiency and Durability

The solid state relay is a game-changer, offering rapid cycling of the elements, incredible temperature control, and extended element life. This means not only accurate firings but also savings on your electrical bill and the peace of mind that comes with long-lasting reliability.

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.)
