Common questions
What electrical service does the FL53E require?
The FL53E requires 3-phase electrical service at either 240V or 208V. This is commercial/industrial power that most residential locations do not have. You will need a licensed electrician to verify your facility has 3-phase service and to hardwire the kiln to a dedicated circuit with appropriate breaker and wire gauge. Three-phase kilns are typically installed in studios, universities, production facilities, and commercial buildings with industrial electrical infrastructure.
Does this kiln come with shelves and furniture?
No. Kiln furniture is not included with the FL53E due to the wide variation in loading requirements for different work. At 53 cubic feet, furniture costs can be significant. We recommend consulting with our team to design a custom furniture package based on your typical firing load—whether that's production pottery, sculpture, or mixed work. We can provide shelves, posts, stilts, and shelf support systems sized for the 46″ × 46″ interior.
Can this kiln fire ceramics and glass?
The FL53E is designed specifically for ceramic work and fires to Cone 10. It is not recommended for glass fusing or slumping. Glass requires significantly lower firing temperatures (1200-1500°F), slower ramp rates, and different element configurations. For glass work, Olympic offers dedicated glass kilns with appropriate controllers and heating profiles.
How is the warranty activated?
Olympic Kilns provides a one-year limited warranty that must be registered within 30 days of delivery. Registration is completed online at Olympic's website with your serial number and proof of purchase. Warranty coverage is valid only when the kiln is purchased through an authorized dealer like Peach State Pottery and installed according to Olympic's specifications. Extended warranty options may be available at time of purchase.
What is the typical firing cost for this kiln?
Firing costs depend on your local electricity rates, firing temperature, and program. A Cone 10 firing in the FL53E will use substantial power due to the 53 cubic foot capacity. At average commercial electricity rates of $0.12/kWh, expect higher per-firing costs than smaller kilns, but significantly lower cost per cubic foot when firing full loads. Many production studios find the FL53E economical when consistently firing near capacity. We can help you calculate estimated costs based on your usage patterns.
