Go Big AND Bring Home Your New Custom-Designed 3031HE Oval Electric Kiln

Embark on your artistic journey with the Olympic Kilns 3031HE Oval Electric Kiln, a symbol of innovation and flexibility in the art world. This oval-shaped kiln is thoughtfully designed to support a variety of artistic expressions, offering a vast vertical space and positioning itself as a vital tool in your creative evolution.

Roomy Interior for Ambitious Artistic Endeavors

The 3031HE impresses with its incredibly spacious interior, measuring 42″W x 30″ front-to-back x 33.5″D. Whether you're working on large sculptures, intricate ceramic creations, or other sizable art pieces, this kiln provides the perfect environment to bring your most ambitious projects to life. With the ability to reach Cone 10 – 2350°F/1288°C, the 3031HE ensures consistent and effective firing across various materials.

Innovative Oval Design for Diverse Artistic Applications

The 3031HE’s oval shape, reinforced by 3” thick brick walls and an additional 2" layer of blank brick for superior insulation, is ideal for supporting wide and tall artworks. This design enhances the kiln's operational efficiency and longevity, meeting the demands of professional artists seeking both performance and durability.

Cutting-Edge Construction for Optimal Functionality

This kiln incorporates Olympic’s advanced electrical box design, equipped with heat shields to keep components at optimal temperatures. Strategically placed heating elements provide even heat distribution, which is essential for achieving uniform results across all your creative projects.

Modern Features for Precise Artistic Control

The 3031HE comes standard with the Digital KilnStar controller, a user-friendly system that offers precise control over your firing process. With features like delay start, preheat, and cone offset, the KilnStar makes it easy to program detailed firing schedules. It’s ideal for artists looking for a straightforward yet powerful firing experience.

For those seeking even more control, the Genesis touchscreen controller is available as an upgrade. The Genesis adds a sleek, modern interface with expanded programming options for artists who require extra precision in their firing techniques.

Tailored Enhancements for Detailed Artistic Expression

The advanced controllers available for the 3031HE, KilnStar and Genesis, offer features like skip-step and extensive firing profiles, allowing you to fine-tune every firing cycle to your exact specifications. This level of control ensures that your art is fired with precision, giving you the freedom to achieve your creative vision.

Customizable Add-Ons for Specific Artistic Requirements

The 3031HE can be further customized to meet your specific needs. Whether you're looking for 1-phase or 3-phase wiring, or need 208 or 240 volts, the kiln can be tailored to fit your studio setup. For more specialized requirements, including 480 volts, Pottery Pulse can assist with additional configurations.

Versatility Beyond Traditional Ceramic Arts

While the 3031HE excels in pottery and ceramics, it’s also a fantastic choice for glasswork and specialized heat-treating processes. For glass projects, consider adding the optional dual-media lid element to expand the kiln’s capabilities even further.

For optimal performance across all media, Solid State Relays are highly recommended. These relays offer quieter, more precise operation and extend the lifespan of your kiln, making them a valuable addition to any setup.

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.)
