Jen-Ken AF3C 1815 Ceramic Kiln

The Jen-Ken AF3C 1815 is a high-performance small kiln designed for artists who want professional results at home. Operating on a 30-amp dryer circuit, it’s simple to install and powerful enough to fire up to Cone 8, making it perfect for pottery, ceramics, and glaze work in home studios or small classrooms.

Built from durable 2,300°F firebrick, this kiln combines energy efficiency with long-lasting performance. Its compact footprint fits easily into tight spaces while still offering the firing depth needed for a variety of projects—from test tiles to small functional ware.

Choose Your Controller

The AF3C 1815 comes standard with the Orton AF3C 3-Button Controller (AF4X), offering precise digital temperature control and easy programming. It includes preloaded fiber-kiln schedules that fire faster than traditional brick kiln programs, plus 25 blank user slots for storing your own custom firing profiles.

Upgrade options give you even more control and flexibility:

• Orton AutoFire 12-Key Controller (AF/AFG) – A robust upgrade supporting multiple thermocouples for zone control, allowing for exceptional temperature uniformity across the kiln. Perfect for advanced users who demand accuracy.

• Orton AutoFire Slide Touchscreen Controller – A modern touchscreen interface with smooth P-I-D temperature control and up to 35 programmable firing schedules.

• TAP II Touchscreen Controller by SDS Industries – The top-tier option with Wi-Fi capability, intuitive operation, and unlimited program storage for ultimate creative freedom.

Optional Upgrades to Enhance Performance

Solid State Relays (SSRs) – Upgrade from mechanical relays to SSRs for quieter, more precise firing cycles and extended component life. They deliver smoother power modulation, improving temperature stability for glass or long hold firings.

Furniture Kit – Expand your kiln’s versatility with a furniture kit that includes shelves, posts, and kiln wash. Ideal for optimizing space and maintaining even heat distribution during multi-level firings, whether you’re bisque firing, glazing, or experimenting with mixed media.

3" Insulated Brick Upgrade – For artists who fire frequently or to higher temperatures, the optional 3" firebrick insulation provides superior heat retention and energy efficiency. It allows faster heat recovery between firings and greater temperature consistency throughout the chamber—ideal for those seeking professional-grade performance in a compact kiln.

Choose the voltage that matches the electrical service where the kiln will be installed. Some kilns are available in only one voltage, while others can be ordered in multiple voltages. If both 120V and 240V are available, 240V is generally the preferred choice because it places less demand on your electrical system, while 120V offers the convenience of operating on a dedicated standard household circuit. If both 208V and 240V are available, select the voltage that matches your building's electrical service—240V is most common in homes, while 208V is common in many commercial, educational, and institutional buildings. If you're unsure which voltage you have, confirm it with your electrician before ordering.

Your kiln must be built to match the electrical service where it will be installed. Choose single-phase if that's what your building has (almost all homes do). Choose three-phase only if your building has three-phase power available. If both are available, three-phase is generally the preferred option. If you're unsure, verify the available electrical service with your electrician before placing your order.

Mechanical relays are standard and reliable. Solid-state relays (SSR) offer silent operation, faster cycling, greater precision, and longer lifespan—ideal for frequent or high-accuracy firings.

The following controllers are used across kilns sold by Pottery Pulse. Not all models offer every option—available controllers are listed on each product page. Some kilns include only the standard controller, while most allow upgrades for added precision and convenience.

Not all kilns can use a collar, but Olympic’s Hot Box kilns can be ordered with a collar to expand versatility. A blank collar simply adds height to the firing chamber, while a bead collar adds the same height and includes a built-in bead or annealing door for quick-access lampwork projects.

This safety feature automatically cuts power to the heating elements whenever the kiln lid or door is opened. It prevents accidental burns, protects elements, and resumes power only when safely closed. (Also called an automatic lid shutoff on Olympic kilns.)
