Olympic Kilns · Electric Kiln · Glass Fusing Olympic Square 146GFE Glass Kiln Model Square 146GFE · 120 Volt · 14.5″ W × 14.5″ D × 6″ H · Fires to 1700°F 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 120V NEMA 5-20 outlet and reaches 1700°F, making it ideal for jewelry studios, small glass projects, and PMC firing. The Bartlett KilnStar digital controller provides precision glass fusing programs with adjustable ramp and hold segments.

Common questions
Can I plug this kiln into a regular wall outlet?
Only if it is a 20-amp outlet. The Square 146GFE operates on 120-volt power, and it has a NEMA 5-20 plug and draws 16 amps, so it needs a 20-amp NEMA 5-20 outlet on a dedicated 20-amp circuit. If you don't have one, an electrician can install it. 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 controller handle glass firing?
The KilnStar controller supports 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.

Common questions about this kiln

Still stuck? Call or text (470) 264-3563 and talk it through with a real person.

Is freight delivery included in the price?

No. Kiln prices do not include freight, and we do not quietly build it into the product price. Freight is charged at a flat rate based on your delivery address and is shown at checkout. Liftgate service is included when it is needed, and standard delivery is curbside. You can estimate your delivered cost with the ZIP code tool above the Add to Cart button.

Can I return this kiln if it is not right?

Return requests can be submitted within 30 days of delivery. The kiln needs to be in its original packaging, in new and resellable condition, and approved before it is sent back. A restocking fee may apply. Completing the manufacturer's recommended first test firing does not by itself make a kiln non-returnable, so you can confirm it works before you commit. Full terms are on our Returns page.

What electrical supply do I need for this kiln?

The Specifications tab on this page lists this model's voltage, amperage, required breaker size and NEMA plug configuration. Most 240V kilns need their own dedicated circuit fitted by a licensed electrician, while many 120V models run from a standard household outlet. If you are unsure what your space can support, call or text (470) 264-3563 before ordering.

Does this kiln come with a warranty?

Yes. This kiln carries the Olympic Kilns manufacturer warranty. Coverage length, what is included and any registration deadline are listed in the Specifications tab on this page. We are an authorized Olympic Kilns dealer, which is a condition of warranty coverage on most kiln brands.

What comes with the kiln, and what do I need to buy separately?

The What's Included tab on this page lists exactly what ships with this kiln. Most kilns need shelves, posts and kiln wash before your first firing, and these are not always included. A vent is recommended for indoor installations. Any add-ons available for this model are shown above the Add to Cart button.
