Paragon Pearl 4426 Glass Fusing Kiln

Built for professional glass artists, production studios, and advanced educational programs, the Paragon Pearl 4426 delivers exceptional firing capacity, precise digital control, and dependable performance for fused glass panels, slumping, casting, decorative installations, and high-volume production work. Its expansive chamber, programmable heat distribution system, and lift-top access design make it an excellent kiln for artists creating large-scale or technically demanding projects.

The Paragon Pearl 4426 is designed for efficient workflow and reliable large-format firing. Its lift-top lid opens smoothly with heavy-duty air pistons, giving artists open access from three sides for easier setup and safer handling of large or delicate glass arrangements.

Inside the kiln, the spacious chamber accommodates a 42" x 24" shelf, providing ample room for fused panels, deep slumping molds, casting projects, and multi-piece production firings. Artists can assemble projects directly inside the kiln chamber to reduce movement and minimize disruption of fragile glass layouts before firing.

The kiln features both top and sidewall heating elements for balanced thermal performance across large firing surfaces. Quartz-protected lid elements help maintain a cleaner firing environment, while adjustable power ratio control allows artists to fine-tune top and side heat distribution for complex firing applications.

Built for demanding studio use, the Pearl 4426 includes 3" firebrick insulation, integrated locking casters, and configurable relay options including mercury displacement relays or upgraded solid-state relays depending on studio preferences and local regulations.

Important: Mercury displacement relays are restricted in CA, IL, CT, MN, ME, MA, NH, NY, RI, and VT. Customers in these states may require a solid-state relay configuration. Please contact us before ordering for assistance selecting the correct configuration.

The kiln is equipped with the SENTINEL Smart Touch digital controller, offering advanced ramp-hold programming, firing schedule storage, real-time temperature monitoring, and intuitive touchscreen operation for slumping, casting, annealing, and specialty glass firing applications.

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.)
