Optional accessories
Glass Kiln Furniture Kit
Includes kiln-washed ceramic shelves, shelf posts in various heights, and fiber paper specifically sized for glass fusing applications in the Square 149GFE.
Solid State Relay (SSR) Upgrade
Replaces mechanical contactors with silent solid-state switching for quieter operation, extended element life, and more precise temperature control during critical annealing phases.
Orton Kiln Vent System
Downdraft ventilation system removes fumes from glass binders, coatings, and inclusions while maintaining temperature uniformity and creating a safer studio environment.
Type K Thermocouple Replacement
Precision-grade spare thermocouple for accurate temperature measurement. Recommended to keep on hand for minimal downtime during critical production schedules.
Power Interrupt Module
Automatically shuts down the kiln if power is interrupted and restored, preventing uncontrolled reheating that could damage glass projects or create safety hazards.
Emergency Parts Kit
Includes critical spare parts like relays, thermocouple, fuses, and element connectors to minimize downtime and keep your kiln operational during urgent production needs.
Digital Pyrometer
Independent temperature monitoring device for verification of controller accuracy and peace of mind during extended annealing cycles and valuable glass projects.
Kiln Sitter Cone Kit for Glass
Assortment of low-temperature pyrometric cones suitable for glass work, providing visual temperature verification and backup safety for fusing and slumping firings.
Controller upgrade
Genesis Touchscreen — Bartlett InstrumentsRecommended
The Genesis controller brings modern touchscreen convenience to glass firing with expanded programming capacity, real-time firing graphs, and advanced features specifically beneficial for complex fusing and annealing schedules. The large color display shows heating rate, target temperature, and current progress at a glance.
- 6-segment programming per step with up to 32 steps for complex glass schedules including controlled cooling and precise annealing
- Full-color touchscreen with intuitive interface displays firing curves in real-time for immediate feedback on heating and cooling rates
- Store up to 100 custom programs for different glass types, project sizes, and firing techniques including fusing, slumping, and annealing
- Delay start and time-of-day firing let you schedule firings to complete overnight or during off-peak electricity hours
- Alarm notifications and program completion alerts with detailed diagnostic information for troubleshooting and safety monitoring
- USB port allows firmware updates and program backup/transfer between kilns for consistent results across multiple studios
Common questions
What types of glass projects can I fire in the Square 149GFE?
This kiln is designed for fusing, slumping, annealing, and casting projects up to 14″ square. The 1700°F maximum temperature handles all standard fusible glass including Bullseye, Spectrum, and Uroboros, as well as borosilicate annealing. The 9″ chamber height accommodates multiple shelf levels for small jewelry pieces or single-layer work for larger plates, bowls, and art panels. The front-loading design makes it particularly convenient for slumping operations where you need to check mold alignment.
Do I need an electrician to install this kiln?
Yes, professional installation by a licensed electrician is required. The Square 149GFE draws 20.8 amps at 240V and requires a dedicated 30-amp circuit with 10 AWG copper wire. Your electrician will need to install the appropriate breaker and either hardwire the kiln or install a NEMA 6-30 receptacle depending on your preference. The kiln can also operate on 208V single phase with slightly reduced performance. Always follow local electrical codes and obtain necessary permits.
Does the kiln come with shelves and posts for glass work?
The kiln does not include kiln furniture in the base price. You'll need to purchase an optional glass kiln furniture kit that includes properly sized ceramic shelves (14″ × 14″), shelf posts in various heights for stacking, and fiber paper. It's essential to use kiln wash or fiber paper between glass and shelves to prevent fusion. We recommend purchasing the furniture kit at the same time as your kiln so you're ready to fire immediately upon installation.
How does the front-loading design compare to top-loading for glass work?
Front-loading kilns like the Square 149GFE offer significant advantages for glass artists. You can easily view your work at eye level when loading, check shelf alignment for slumping molds, and access projects without reaching down into a hot chamber. The door design also allows you to crack it open slightly to check firing progress during critical stages. The trade-off is a slightly smaller chamber capacity compared to equivalent top-loaders, and the door hinge requires occasional maintenance to ensure proper sealing.
How is the warranty activated and what does it cover?
Olympic Kilns provides a one-year limited warranty that must be registered within 30 days of delivery to be valid. The warranty covers manufacturing defects in materials and workmanship but does not cover normal wear items like elements, thermocouples, and firebrick, which degrade naturally with use. The warranty is only valid when purchased through authorized dealers like Peach State Pottery. Keep your purchase receipt and register online at Olympic's website immediately after delivery. Damage from improper installation, incorrect voltage, or misuse is not covered.
