Common questions
What electrical service does the 1827HE require?
The 1827HE requires a dedicated 40-amp circuit with 240V single-phase power (50-amp at 208V single-phase in commercial settings). You'll need #8 copper wire (#6 for runs over 40 ft) run from your breaker panel to a NEMA 6-50 receptacle. Most residential installations require a licensed electrician to install the circuit and outlet. The kiln draws 31 amps at 240V (7,560 watts), so verify your electrical service panel has sufficient capacity before installation.
Does this kiln come with shelves and posts?
No, kiln furniture is sold separately. The 1827HE requires a furniture kit specifically sized for its 17.5-inch diameter chamber. A typical furniture kit includes 3-4 full round cordierite shelves and approximately 9-12 posts in varying heights. You'll want kiln furniture rated for cone 10 firing to match the kiln's maximum temperature capability.
What does the stackable design allow me to do?
The three-section stackable construction means the top, middle, and bottom sections separate completely. This makes the kiln easier to move through doorways and up stairs during initial installation. In the future, you can add or remove sections to change the chamber height (creating an 18-inch or 36-inch tall chamber instead of 27 inches), or you can purchase additional sections to build a second kiln using some of your existing sections. Each section contains its own heating elements.
How is the warranty activated?
Olympic requires warranty registration within 30 days of delivery to activate the one-year limited warranty. You'll need to register directly with Olympic Kilns (not with Peach State Pottery) and provide proof of purchase. The warranty only covers defects in materials and workmanship when purchased through authorized dealers. Wear items like elements, thermocouples, and relays have separate coverage terms outlined in the warranty documentation.
Can this kiln fire glass as well as ceramics?
Yes, but you'll want the dual-media lid conversion accessory for optimal glass fusing results. The standard ceramic lid configuration works for glass firing, but the dual-media system includes a lower-profile lid specifically designed for glass work that provides better heat distribution for fusing and slumping. The KilnStar controller can be programmed for glass firing schedules with appropriate ramp and hold segments for glass projects.

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.
