Pearl 4426 Glass Kiln

PARAGON PEARL 4426: Master-Level Kiln for Monumental Glass Creations

The Paragon PEARL 4426 is a powerhouse built for professionals who push the boundaries of glass art. With its 44-inch wide interior, 26-inch depth, and smart lid-lift design, this kiln makes it possible to fire expansive glass panels, deep casting molds, or production loads of pendants in a single cycle. Whether you run a busy studio or produce large-scale works, the PEARL 4426 gives you the performance, precision, and durability to bring your vision to life.

Assemble Directly Inside the Kiln

Forget transferring fragile glass setups across the room. With the PEARL 4426, the entire top lifts open with the help of heavy-duty air pistons and a 50-inch handle, giving you access from three sides. Position your 42" x 24" shelf, compose your design in place, then gently close the lid. A woven rope gasket and sealed lid surfaces ensure a tight, cushioned fit for safe, repeatable firings.

Designed for Clean, Even Heat

• The lid’s heating elements are protected inside six quartz tubes, keeping the interior cleaner while minimizing element exposure to dust or contamination.

• Sidewall heating elements are mounted in recessed grooves for optimal heat distribution across large surfaces.

• Paragon’s power ratio technology lets you control top vs. side heat distribution in precise 10% increments—perfect for balancing thermal gradients across complex designs or slumping delicate forms.

• Twin pilot lights let you know at a glance whether the lid or side elements are active.

Rugged Construction, Smooth Operation

• The PEARL 4426 features 3-inch thick firebrick walls, lid, and floor—half an inch thicker than many kilns on the market.

• A ceramic fiber expansion joint in the lid and base helps extend kiln life and reduce cracking under thermal stress.

• A heavy tubular steel frame gives the entire firing chamber rigid support, with welded leg plates ready for optional 2-inch steel locking casters.

• Electrical components are mounted low inside a ventilated switch box with a dual heat-shield system and air gap for cooling efficiency.

Industrial-Grade Reliability

• Equipped with mercury relays for ultra-long relay life and silent switching, this kiln is designed for non-stop production cycles.

• The exposed-tip Type-K thermocouple delivers fast, accurate temperature readings with special-limit wire built to Paragon's specifications.

• Costly, heavy-gauge nickel-plated copper wiring is protected with high-temperature glass-braided insulation for safety and longevity.

Precision Control with SENTINEL 

The PEARL 4426 is now powered by the SENTINEL Smart Touch controller, Paragon’s intuitive digital interface for managing even the most complex firing schedules. Easily program ramp-hold sequences, view real-time temps, check energy usage, and repeat past firings with perfect consistency. The sealed touchpad resists dust and wipes clean in seconds.

Who Is This Kiln For?

• Glass artists working on large fused panels or deep molds.

• Production studios needing efficient, high-capacity firings.

• Professionals who demand maximum control and industry-level reliability.

• Advanced slumping, casting, and specialty glass processes that require programmable heat distribution.
