Jen-Ken AF JK² 29" Ceramic Kiln — Maximum Capacity for Large Ceramic Work

The Jen-Ken AF JK² 29" is built for ceramic artists who need serious firing capacity for oversized pieces, slip-cast molds, yard art, holiday trees, platters, and tall forms. Its generous square interior provides exceptional usable shelf space and easy loading, making it ideal for high-volume studios and community ceramic programs producing large work.

Engineered with heavy 2300°F brick construction and powerful side-firing elements, this kiln excels at frequent low-fire ceramic production (Cone 04–06) with the ability to fire occasional mid-range loads up to Cone 8 when programmed slowly. Standard lid lifters make loading effortless, even with frequent use, and the wide chamber lets you fire large pieces that would never fit in round kilns.

The JK² 29" comes standard as a 45-amp plug-in kiln (NEMA 6-50) with an optional 55-amp direct-wire configuration available for users who want improved power delivery for more demanding cycles or higher-temperature work.

Smart Digital Controller Options

Standard: Orton AutoFire 12-Key Controller
Cone-fire programs, custom schedules, mid-firing edits, holds, skips, and reliable precision for studio workloads.

Upgrade Options:
Orton AutoFire Slide Touchscreen — Intuitive touchscreen firing control
TAP Smart Touchscreen Controller — Wi-Fi, unlimited programs, cloud backup, firing logs, and remote monitoring

Optional Enhancements

Furniture Kit
Add shelves, posts, and kiln wash to maximize space and load flexibility — essential for multi-level bisque and glaze firing.

Solid-State Relay (SSR) Upgrade
Upgrade to silent, precise power control for smoother heating curves and extended relay life — ideal for frequent firing environments.

Lid lifters
Kiln stand
