Compact HotBox Electric Kiln — Big Performance in a Small Footprint
The Olympic HB89E is part of Olympic's HotBox lineup — compact, high-performance electric kilns sized for small studios, jewelry work, testing, and anyone who needs serious firing capability without a huge footprint.
It fires up to Cone 10 / 2350°F, full high-fire capability for ceramics, jewelry, and glass work despite the compact 8" × 8" × 9" chamber — the deepest in Olympic's HotBox lineup.
The HB89E runs on 120V at 15 amps. Total draw is 1,800 watts. Plugs into a standard NEMA 5-15 outlet; requires a dedicated 20A circuit.
Olympic Kilns has been building electric, gas, and glass firing kilns in Flowery Branch, Georgia for over 50 years. Their kilns are used by hobbyists, production studios, schools, and industrial users throughout the US.
Included with every order
Pilot light, metal stand, stainless steel jacket, Bartlett KilnStar digital controller, peephole plugs, full operator manual, a 2 year limited warranty through Olympic, and free freight shipping to the US Lower 48.
You'll pick your digital controller at checkout. Olympic kilns ship standard with the Bartlett KilnStar digital controller — reliable cone-fire and ramp-hold programming via up/down keys. Most studios upgrade to the Genesis touchscreen controller for more ramp-hold programs, custom firing profiles, delay start, preheat, skip-step, and a built-in cone table. Not sure which one fits your workflow? That's exactly the kind of thing we help with.
