Olympic GF15E Large Capacity Glass Fusing Kiln
The GF15E delivers a massive 15 cubic foot firing chamber in a front-loading horizontal configuration designed for production glass studios and large-scale fusing work. At 60 inches wide and 36 inches deep, this kiln accommodates multiple full sheets of glass simultaneously, making it ideal for architectural panels, tabletops, and high-volume slumping operations. The horizontal chamber design provides even heat distribution across the entire shelf surface, critical for uniform fusing and annealing of large glass pieces.

Common questions
What electrical service does the GF15E require?
This kiln requires professional electrical installation by a licensed electrician. It's available in 240V single-phase or 208V three-phase configurations depending on your facility's power availability. Due to the high amperage draw of a 15 cubic foot chamber, you'll need dedicated circuit breakers and appropriately sized wire — contact us for exact electrical specifications for your voltage choice. Most production studios opt for three-phase 208V for more balanced power distribution and lower operating costs.
What size glass work can I fit in this kiln?
The 60″ × 36″ interior accommodates multiple full sheets of standard glass (up to 48″ × 96″ when positioned diagonally) or several smaller projects fired simultaneously. The 12-inch height allows for thick glass casting, multiple-layer fusing, and tall slumping molds. This capacity makes the GF15E ideal for architectural panels, large tabletops, multiple production runs, and commercial glass studio operations.
Do I need to purchase kiln furniture separately?
Yes, kiln shelves, posts, and fiber paper are sold separately to allow you to configure the furniture for your specific glass applications. We recommend custom-sized shelves for the GF15E's large chamber — standard furniture kits won't fit this professional-scale kiln. Contact us to specify shelf dimensions, quantities, and accessories for fusing versus slumping work.
Can this kiln handle full annealing cycles for thick glass?
Absolutely. The 3-inch brick insulation and digital controller provide the precise, slow cooling required for proper annealing of thick cast glass and multi-layer fused pieces. The large thermal mass of the chamber maintains stable temperatures during extended soak periods, and the optional multi-zone control compensates for temperature variations across the wide shelf span. Program extended annealing cycles of 24+ hours for architectural-thickness work.
How is Olympic's warranty activated?
Register your kiln with Olympic Kilns within 30 days of delivery to activate the one-year limited warranty covering manufacturing defects in materials and workmanship. Warranty is valid only on kilns purchased through authorized Olympic dealers like Peach State Pottery. Keep your purchase receipt and complete the registration form on Olympic's website immediately after installation.
