Olympic Kilns · Electric Kiln · HotBox Series · 120V Olympic Kilns HB84E Electric Kiln HB84E · 120V · 8″ W × 8″ D × 4.5″ H · 0.17 cu ft · Cone 10 / 2350°F The HB84E is Olympic's smallest HotBox kiln — a genuinely portable test kiln that still reaches Cone 10, plugging into any standard 120V/20A outlet. It's built for jewelers, testing glazes and clay bodies in small batches, PMC (precious metal clay) work, and enamel firing, and it ships with the Bartlett Spark touchscreen controller standard.

Common questions
Do I need an electrician to install this kiln?
Yes. The HB84E requires a dedicated 20-amp circuit (15 amps) with a NEMA 5-15 receptacle, installed by a licensed electrician according to local electrical codes. Installation by anyone other than a qualified electrician may void your warranty and create serious safety hazards.
What is this kiln typically used for?
The HB84E's small chamber and 120V power make it popular for jewelers and metalsmiths firing PMC (precious metal clay), enamelists, and potters who want to run small glaze and clay body tests without firing a full-size kiln load.
Can it really reach Cone 10 on standard household power?
Yes — despite its 120V/15A draw, the compact 0.17 cu ft chamber and efficient insulation let the HB84E reach Cone 10 (2350°F). Small chambers heat and hold temperature more efficiently per watt than large ones.
Does this kiln come with shelves and posts?
No. Kiln furniture is sold separately because different users have different needs based on the work they're firing. We recommend ordering a furniture kit sized for the 8″ × 8″ chamber when you purchase the kiln.
How do I register my warranty?
Register your kiln at the Olympic Kilns website within 30 days of delivery. You'll need your serial number (located on the control panel label), purchase date, and proof of purchase from an authorized dealer. Peach State Pottery can assist with registration if needed.

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.
