Paragon F240 - Deep Chamber Versatility for Glass Artists
The Paragon F240 is built for lampworkers and flameworking professionals who demand volume, flexibility, and thermal reliability. With a deep, cubic interior and multi-heating configurations, the F240 supports everything from long annealing cycles for large sculptures to simultaneous runs of beads, marbles, or figurines—all with even, stable heat distribution.
Built for Large-Scale Annealing
With a spacious 18.00" W x 18.00" D x 13.00" H firing chamber, the F240 gives you the room to fire large glass pieces or batch-load multiple smaller items without compromising on consistency. Whether you’re annealing large paperweights or working with multiple punty rods through a bead door, the F240 is ready for the job.
Side-Fire Version: Excellent for evenly annealing horizontal work across a wide shelf or base.
Top-Fire Version: Offers radiant heat from above—ideal for domed sculptures or surface-heated pieces.
Top & Side-Fire Version: Best of both worlds—combines radiant and wraparound heat for ultra-stable conditions and complex loads.
Professional Control & Performance
Sentinel Touch Xpress Controller: Tap through customizable programs with ramp/hold segments and full Novice Mode assistance. Save up to 12 unique schedules for fast, accurate repeat firings.
3" Firebrick Insulation: Heavy-duty brick walls maintain stable temperatures and slow cooling curves, ideal for fragile or complex glass projects.
Solid-State Relay (SSR) or Mechanical Door Relay (MDR): Choose between silent, long-lasting SSR models or rugged MDR control, depending on your studio preference. All units are built with workshop-ready electrical integrity.
Bead Door Access: F240 units come standard with a bead door—ideal for inserting punty rods mid-session while maintaining internal heat. Perfect for continuous lampworking flow.
Drop-Switch Door Safety: Heating elements automatically shut off when the door is opened—an essential safety feature for real-time annealing environments.
Ideal For:
- Artists working with large beads, marbles, or sculptures
- Studios producing medium-to-high volumes of lampworked pieces
- Makers needing multiple heat source configurations for different glass styles
- Educators or workshop leaders firing various shapes and sizes
Furniture Kit Includes:
1 - 16" x 14" square shelf
4 - 1" square post, 1/2" tall
1 - 1lb bag glass separator
Built with Pride in Mesquite, Texas
Each Paragon F240 is handcrafted with the precision and care that glass artists expect. With its generous depth, flexible heating options, and rock-solid construction, the F240 is the professional’s tool for serious lampworking and flawless annealing.
All Paragon Kilns now come standard with a Sentinel/Sentinel Xpress Touchscreen controller.
Paragon F-240 Lamp Working Kiln
Anneal large glass figurines in the digital F-240 lamp working kiln. Raise the spring-loaded vertical-drop door to insert a glass figurine with a punty rod. Lower the door. The punty rods or mandrels will extend outside the firing chamber through the small punty rod doors. This allows even large glass pieces to anneal safely.
Punty rod doors retain the heat
Two 4" x 7 1/2" punty rod doors will give you plenty of room to work with. Because of a gap under the punty rod doors, you can usually close them all the way even when mandrels extend past the firing chamber. Two layers of woven gaskets under each door help to hold in the heat. Powerful rare-earth magnets hold the punty rod doors in the open and closed positions. To help retain heat, the ceramic fiber punty rod doors are 2" thick.
Adjustable slide-out mandrel holder
We have added an adjustable mandrel holder to the front of the kiln. Adjust it horizontally and vertically without tools. Position the heavy-duty welded mandrel holder from 1 1/4" to 12" from the front edge of the main floor. (A firebrick extension on the front of the kiln fits under the punty rod doors beyond the front edge of the kiln floor.) Then tighten the mandrel holder with the thumb screws on each side of the kiln. The holder slides inside steel tubes mounted in the base of the kiln. The stainless steel mandrel rest, which includes 14 slots, can also be adjusted vertically.
New thicker firebricks in the F-240
The firebricks in the roof, walls, door, and bottom are 3" thick. This is 20% more insulation than the standard 2 1/2" firebricks in the walls and bottom of our earlier F-240 kilns. The extra insulation enables the F-240 to maintain a temperature hold with greater ease. A firebrick ledge extends 3" past the punty rod doors as a handy working surface.
Safety testing
For your safety the F-240 is rigorously tested by TUV to meet UL and CSA standards. TUV is Germany’s leading testing lab. We can make the F-240 for any electrical system in the world. The F-240 includes a safety on/off switch for your convenience. Electrical components stay cool in a slotted base.
Sidewall elements are now standard in the F-240
The F-240 elements heat from the sides and back of the kiln in dropped, recessed wall grooves. (This type of groove protects the elements.)
- On/off switch for rebooting the controller
- Safety pilot light
- Elements in the walls, protected in dropped, recessed grooves
- 3" insulating refractory firebricks throughout the firing chamber
- Optional door safety switch
- Electrical components stay cool in a slotted base. No extra stand is needed.
- Long-life electrical system
- Coated roof for extra durability
- Precisely balanced spring-loaded vertical-drop door
- 2 - 4" x 7 1/2" punty rod doors
- Double gaskets under the 2" thick punty rod doors
- Rare earth magnets hold the punty rod doors open or closed.
- TUV tested to UL and CSA standards
- Mar-proof plastic feet
- Made in the USA.
Made in USA
The F-240 is made at the Paragon factory in Mesquite, Texas USA. We are open from 7 a.m. to 5:30 p.m. Central Standard Time, Monday through Thursday. Our expanded hours allow us to serve customers in differing time zones. Call us, we look forward to hearing from you.
Thermocouple with "special limit" wire
The thermocouple senses temperature inside the kiln. It is the small rod that extends into the firing chamber. The ¼" wide Type-K, 14-gauge, exposed-tip thermocouple is made with special-limit wire for superior accuracy. The exposed tip gives the controller a fast response time for even temperatures during holds. The thermocouple is made in America to our exacting standards.
Designed for production
Paragon’s warranty is not affected by frequency of use. Fire your new kiln every day if you want, even in commercial settings. That will have no effect on the warranty period.
Optional colors at no extra charge
Brighten your studio with color! Order your kiln in one of our standard colors at no extra charge . . . berry, black, blue, hot pink, jade, navy, purple, or turquoise.
Please note that free shipping is only valid for the contiguous United States.
