At 30 inches wide and 20 inches front-to-back, this 7.2 cubic foot kiln fires to cone 10 on 240V single-phase power with the KilnStar digital controller.

Common questions
What electrical service does the 2023HE require?
The 2023HE requires 240V or 208V single-phase power. At 240V it draws 48 amps on a 60-amp dedicated breaker and connects to a NEMA 6-50 receptacle; at 208V it draws 55 amps on a 70-amp breaker and is direct wired. A licensed electrician should install the circuit using 6 AWG copper wire minimum. It cannot be plugged into a standard outlet. You'll need to verify your electrical panel has capacity for this load before installation.
Does this kiln include kiln shelves and posts?
No, furniture is sold separately. Because the 2023HE has an oval chamber, you'll need custom-sized oval or rectangular shelves. We recommend ordering a furniture kit designed specifically for this model to maximize usable space and ensure proper fit within the 30″ × 20″ chamber.
What makes the oval shape advantageous over a round kiln?
The 30-inch width accommodates large platters, oval serving pieces, and wide sculptural forms that won't fit in standard 23-inch round kilns. The 20-inch depth keeps the footprint smaller than a 30-inch square kiln while still providing 7.2 cubic feet of capacity. This shape is particularly valuable for production potters making dinnerware with large serving pieces.
Can this kiln fire stoneware and porcelain to full maturity?
Yes, the 2023HE fires to cone 10 (2350°F), which covers all standard ceramic clay bodies including high-fire stoneware, porcelain, and cone 10 glazes. The 3-inch brick provides the insulation needed for efficient high-temperature firings with proper heat retention.
How is the Olympic warranty activated?
Olympic's one-year limited warranty must be registered within 30 days of delivery. Registration is done through Olympic Kilns directly. The warranty is only valid when purchased through authorized dealers like Peach State Pottery, and covers defects in materials and workmanship under normal use.

Common questions about this kiln

Still stuck? Call or text (470) 264-3563 and talk it through with a real person.

Is freight delivery included in the price?

No. Kiln prices do not include freight, and we do not quietly build it into the product price. Freight is charged at a flat rate based on your delivery address and is shown at checkout. Liftgate service is included when it is needed, and standard delivery is curbside. You can estimate your delivered cost with the ZIP code tool above the Add to Cart button.

Can I return this kiln if it is not right?

Return requests can be submitted within 30 days of delivery. The kiln needs to be in its original packaging, in new and resellable condition, and approved before it is sent back. A restocking fee may apply. Completing the manufacturer's recommended first test firing does not by itself make a kiln non-returnable, so you can confirm it works before you commit. Full terms are on our Returns page.

What electrical supply do I need for this kiln?

The Specifications tab on this page lists this model's voltage, amperage, required breaker size and NEMA plug configuration. Most 240V kilns need their own dedicated circuit fitted by a licensed electrician, while many 120V models run from a standard household outlet. If you are unsure what your space can support, call or text (470) 264-3563 before ordering.

Does this kiln come with a warranty?

Yes. This kiln carries the Olympic Kilns manufacturer warranty. Coverage length, what is included and any registration deadline are listed in the Specifications tab on this page. We are an authorized Olympic Kilns dealer, which is a condition of warranty coverage on most kiln brands.

What comes with the kiln, and what do I need to buy separately?

The What's Included tab on this page lists exactly what ships with this kiln. Most kilns need shelves, posts and kiln wash before your first firing, and these are not always included. A vent is recommended for indoor installations. Any add-ons available for this model are shown above the Add to Cart button.
