Olympic Square 146GFE Glass Kiln
The Square 146GFE is a compact 120-volt glass kiln designed for fusing, forming, and precious metal clay work in a 14.5″ × 14.5″ × 6″ chamber. This countertop-friendly kiln plugs into a standard household outlet and reaches 1700°F, making it ideal for jewelry studios, small glass projects, and PMC firing. The GFE controller provides precision glass fusing programs with adjustable ramp and hold segments.

Common questions
Can I plug this kiln into a regular wall outlet?
Yes. The Square 146GFE operates on standard 120-volt household power and plugs into any 15-amp or 20-amp outlet. A dedicated circuit is recommended for best performance, but no special electrical installation or electrician is required. This makes it ideal for studios, classrooms, and home workshops without 240V service.
What glass fusing applications can this kiln handle?
The 1700°F maximum temperature is perfect for full fusing, tack fusing, slumping, and annealing of glass up to 14″ × 14″. You can fire dichroic glass, frit work, jewelry-scale pieces, small plates and bowls, and test tiles. It's also excellent for precious metal clay (PMC) firing, which requires similar temperature ranges and controlled ramping.
Do I need to purchase kiln furniture separately?
Yes. Glass kiln furniture (kiln-washed shelves, shelf paper, and posts) is sold separately to allow you to configure the setup for your specific glass fusing needs. We recommend ordering a furniture kit sized for this 14.5″ × 14.5″ chamber when you purchase the kiln to begin firing immediately upon delivery.
How does the GFE controller differ from standard ceramic kiln controllers?
The GFE controller is specifically programmed for glass work with adjustable ramp and hold segments that match glass fusing schedules. It allows you to program precise heating rates (critical for avoiding thermal shock in glass), extended hold times at fusing temperatures, and controlled annealing cycles. This level of control is essential for successful glass work but unnecessary for ceramic firing.
How do I activate the Olympic Kilns warranty?
Register your kiln at the Olympic Kilns website within 30 days of delivery to activate the one-year limited warranty. Keep your purchase receipt from Peach State Pottery, as warranty coverage is valid only through authorized Olympic dealers. The warranty covers manufacturing defects in materials and workmanship but does not cover normal wear items like elements and thermocouples.
