Paragon CT122829 Janus Ceramic and Glass Kiln

The Paragon CT122829 Janus delivers massive capacity, dual-mode firing, and dependable cone-10 performance in a high-volume kiln designed for studios working in both ceramics and glass. With a 28″ interior diameter and 29″ depth (10.57 cu ft), it offers exceptional space for tall sculptural work, large platters, and full multi-shelf production loads. Built on Paragon’s proven Ceramic Top platform, this model combines industrial-level capacity with the flexibility of Janus dual-mode firing—making it a true powerhouse for production studios, schools, and serious artists. Upgraded to 48 amps, this kiln provides faster heat recovery and more consistent performance during demanding firing cycles. It 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 large, multi-sided chamber promotes even heat distribution, while sectional construction allows the kiln to be separated for easier maintenance, transport, or installation in tight spaces. A top row of grooveless blank bricks helps reduce interior wear, and the reversible firebrick floor extends the kiln’s working life. 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 large-format glass—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 CT122829 Janus an excellent choice for high-output studios or institutions that need one kiln to handle multiple disciplines without compromise. Controller The CT122829 Janus includes the Sentinel SmartTouch Controller, featuring a large 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 eight C-24H shelves (26″ octagon × 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 airflow, 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.
