Ships in 12-15 weeks · freight to your door

Olympic Kilns builds most kilns to order once your order is placed, so plan on about 12-15 weeks before it leaves the factory. We email your confirmed ship date and tracking.

  • The freight carrier calls you to book a delivery window.
  • Delivery is curbside with a liftgate. Have a helper or hand truck to move it inside.
  • Check the crate before you sign. Note any damage on the receipt and send us photos.

Enter your ZIP in the freight estimate below to see the delivered cost.

Authorized Olympic dealer · full factory warranty

Brand new and shipped direct from Olympic Kilns, so it carries Olympic's full factory warranty. If something goes wrong, call us and we handle the claim with the factory for you.

Warranty terms are in the Warranty and support section below.

Returns: request within 15 days, unused

Because kilns are heavy and often built to order, returns are limited, so we'd rather help you pick the right one up front:

  • Ask within 15 days of purchase or 2 days after delivery, whichever comes first. We issue a return authorization (RA).
  • It must be new, unused (beyond the factory test fire) and in its original packaging.
  • A restocking fee of at least 25% applies, up to 50% on custom, 3-phase or made-to-order units. Return freight is on the buyer unless we made an error.
  • Damaged in transit? Note it on the delivery receipt, send us photos and we'll help with the freight claim.

Will it work in my space? Power check

Not included: kiln shelves, posts, kiln wash and vent (sold separately). No plug: direct-wired to a dedicated 60-amp (240V) or 70-amp (208V) circuit by an electrician.

Most 240V kilns need their own circuit and the matching outlet, installed by an electrician. Homes are usually 240V; schools and commercial buildings are often 208V, so pick the voltage that matches your panel.

Send us a photo of your breaker panel or outlet and we'll confirm before your kiln is built: 470-264-3563 (call or text).

Overview

Olympic Kilns · Electric Kiln · Oval Top-Loading Olympic 2023HE Oval Electric Kiln Model 2023HE · 240V or 208V · 30″ W × 20″ D × 24.5″ H · 7.2 cu ft · Cone 10 / 2350°F The 2023HE features a unique oval chamber design that maximizes capacity for large platters, oval serving pieces, and wide sculptural work that won't fit in standard round kilns. 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. The oval footprint saves floor space compared to square kilns while providing generous width for oversized functional ware.

What’s included
The kiln, with its elements installedThe brick sections arrive with Olympic's heavy gauge coiled elements already set in their grooves and wired. This kiln ships as sections on a pallet together with its stand: the manual has you take the sections off the pallet and restack them on the stand where the kiln will live.
Bartlett KilnStar controller, fitted and wiredThe KilnStar is the standard controller on this kiln and it is installed and wired at the factory. The Genesis touchscreen is a paid upgrade taken at order time, and Olympic's 2026 range no longer offers the RTC-1000, Kiln Sitter, 3-key or V6-CF, so nothing legacy ships here.
One Type K thermocouple and the pilot lightA single Type K thermocouple comes installed and wired to the controller. The control panel also carries a pilot indicator light that comes on whenever the kiln is live. Extra thermocouples only arrive with the 2-zone or 3-zone option, and a Type S is a paid substitution.
The combined lid lift and standOlympic's oval line ships one assembly that is both the stand and the lid lift, so the lid assist is built into the stand rather than added to it. The manual requires it: “Your kiln must be fired only on the metal stand provided.”
Observation plugsHollow ceramic peephole plugs ship with the kiln. Olympic publishes no count for any model, in its manuals or on its site, so we will not print a number here. Ask and we will confirm yours with the factory. Replacements are a stock part.
The operating manual and a one-year warrantyOlympic's printed operating manual travels with the kiln. Olympic's limited warranty runs two years, cut to one year on Kiln-Sitter models and on any kiln rated at cone 10. This one is rated to cone 10, so one year. Register with Olympic within 30 days of delivery and keep your invoice.
Cord and plug, or direct wired, set by your buildOlympic's plug configuration row gives a NEMA 6-30 or 6-50 plug on lower-amperage builds and Direct Wired on higher-amperage ones, and several models are listed as either. The manual hedges the same way, with “If your kiln is equipped with a power cord...”. Tell us your voltage, phase and service and we confirm which one you get before the order goes in.
Not included: furniture, vent and hookupNo kiln furniture. Every Olympic line has its own separately priced furniture kit and shelves and posts are priced one by one. The VentMaster downdraft vent, stilts, gloves, tongs, kiln wash and a pyrometer are all separate items, and no receptacle, breaker, wire or disconnect ships with the kiln.

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.
