Details

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. No extra stand is needed for your kiln.

 

Deluxe mercury relays are standard

 

We have upgraded the F-240 with the deluxe mercury relay, which controls the cycling of the heating elements. The relay is industrial grade and heavy-duty for extra long life. Ask experienced glass artists what they think of the relay.

Glass is fired in the kiln on a shelf. Coat the shelf with glass separator to prevent the glass from sticking to the shelf. Place short posts between the shelf and the kiln bottom to circulate heat around the shelf.

Paragon’s durable cordierite shelves resist warpage and thermal shock. They are volume-stable.

 

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.)

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.

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.

BEAST

This thing, as I said in the title, is a beast!! For one person in the shop its great for all types of sculptural work. Its a very well built kiln and holds the heat with no problems. The Kevlar on the doors is a great addition. I have had mine for a year with no problems. A great investment.

Great kiln from Paragon

I have had this kiln for over a year and it has operated perfectly. The programmable controller works very well with little to no temperature overshoot, holds within a degree or two of the set point, and the ramp feature is very useful. The downside to the controller is that it is not very intuitive to use and every time I program it I still need to refer to the directions. The first time firing the Kiln it does emit a fairly strong odor which is expected but make sure you do this in a well ventilated area. There was no odor on any subsequent firings. The large size of this kiln is great for annealing larger pieces and the punty rod doors make it easy to garage your pieces while still allowing the kiln to retain its heat. The front mandrel rest is fully adjustable forward and back as well as up and down. The 3 inch fire brick does a great job holding in the heat, running at 1050 for hours the outside only get slightly about warm. After over 100 firings I have had no issues.

This is the one :)

For anyone not knowing if this is the right kiln or not. Your answer is yes. I’ve had it for about 3 years now, and have used it almost everyday, except weekends. Usually use it 10-15 hours everyday as well. Hasn’t gave me a single problem. Love it. Best purchase ever. Mountainglass for life.
