F240 Lamp Working Kiln

by Paragon Industries, Inc.

Uses:  Glass Bead Annealing    Lamp Working


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.

The F 240 now has a solid state relay, which lasts far longer than a standard mechanical relay. The solid state relay has no moving parts to wear out. The first thing you will notice is that the solid state relay is silent. You will hear just the reassuring hum of elements. The solid state relay makes heating elements last longer and offers better temperature control during holds.

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 two inches thick.

New 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.

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.


Optional Furniture Kit

Recommended furniture kit for the Paragon F-240 and equivalent sized kilns. Included:

1 - C-17 Shelf (16” x 14” x 5/8”)

4 – 1/2” long, 1” wide Square Posts

1 lb. Bag Glass Separator

Shipping size: 24” long x 24” wide x 9” high

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.)

    If you prefer an element in the top instead of the walls, that option is available for an additional $80.  Top elements are mounted in deluxe pinless element grooves. You can order both top and sidewall elements for an additional $180.
