Paragon CT102322 Janus Ceramic and Glass Kiln

The Paragon CT102322 Janus delivers wide-chamber capacity, dual-mode firing, and dependable cone-10 performance in a versatile kiln designed for studios working in both ceramics and glass. With a 22.5″ interior diameter and 22.25″ depth (5.10 cu ft), it provides generous space for large platters, production pottery, and full multi-shelf loads while remaining accessible for easy loading. Built on Paragon’s trusted Ceramic Top platform, this model combines proven durability with the flexibility of Janus dual-mode firing—making it an ideal centerpiece for busy studios and classrooms.

This kiln features 3″ firebrick insulation throughout, solid-state relays (SSR) for quiet and efficient operation, and a vent-ready, pre-drilled base with an AOP (Auxiliary Outlet Plug) for seamless integration with an optional Orton VentMaster system. Its 10-sided chamber design promotes even heat distribution, while dropped, recessed element grooves eliminate the need for pins and extend element life. A top row of grooveless blank bricks helps reduce interior wear, and the reversible firebrick floor extends the kiln’s working life. Paragon’s patented LiteLid spring system allows smooth, one-handed lid lifting, while the drop-down hinged switch box provides convenient access for maintenance.

The Janus dual-mode system uses dedicated top and sidewall elements, controlled by a simple toggle switch that allows you to switch between glass and pottery firing modes. Glass mode activates the top and mid-side elements for controlled radiant heat—ideal for fusing, slumping, and sagging—while pottery mode uses sidewall elements only to ensure even heat distribution for bisque and glaze firings up to cone 10. This flexibility makes the CT102322 Janus an excellent choice for multi-disciplinary artists or institutions looking to maximize capability without adding another kiln.

Controller

The CT102322 Janus includes the Sentinel SmartTouch Controller, featuring a responsive color touchscreen, cone-fire and ramp-hold programming, user-friendly prompts for both ceramic and glass cycles, firing logs, diagnostics, and scheduling tools for consistent, repeatable results.

Optional Add-Ons

Furniture Kit: Includes six C-23H shelves (20″ round × ¾″), a full set of 1½″ square posts in multiple heights, and kiln wash—everything needed to begin firing immediately.

VentMaster Kiln Vent: This optional system improves heat distribution, enhances glaze consistency, and safely removes fumes. It connects directly to the kiln’s AOP and utilizes the pre-drilled vent port for quick installation.

Kiln Stand Options: Choose between the 6″ Standard Stand with mar-proof feet or the 12″ Deluxe Rolling Stand, recommended when pairing with a VentMaster system.

Please contact us to reach out to the manufacturer for an estimated lead time.

There is currently a firebrick supply constraint affecting several kiln manufacturers, including this model. Because of that, lead times have been extended and can fluctuate.

Rather than guess, we can confirm the current production timeline with the factory before you place your order so you know exactly what to expect.

Higher voltage means lower amperage draw and greater efficiency, which can save money long term. 240V and 208V cost the same—most home studios use 240V, while 208V is common in schools or large facilities. Amperage refers to the amount of electrical current a kiln draws—higher amps require heavier wiring and breakers.

Single-phase is what almost all homes have. If your facility has three-phase, you can choose either—but three-phase is typically the better long-term option due to smoother power and improved efficiency.

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.)
