F500 Lamp Working Kiln

by Paragon Industries, Inc.

Uses:  Glass Annealing    Glass Bead Annealing    Lamp Working  



The kiln is designed for annealing large glass figurines, beads, and marbles. The interior is 24” wide, 22 1/4” high, and 18” deep. Imagine the huge glass pieces you could make with a kiln this large.

The massive F-500, with its towering door counter-weights and handsome black finish, is a workhorse that will raise your production. The F-500 simplifies annealing so you can immerse yourself in creating breathtaking ware.

Raise the counter-weight vertical-drop door to insert glass on a punty rod. Lower the door. The punty rod extends outside the firing chamber through a smaller punty rod door. The main door is balanced so it stays open where you stop it. Maintain the annealing temperature indefinitely with the Sentry Xpress 3-key controller.

The punty rod doors retain the heat

The main door includes two 4” x 10 1/2” punty rod doors. Two flexible gaskets under each door help to retain the heat. The punty rods can extend outside the kiln through the gap under the doors. This allows the doors to remain fully closed. The ceramic fiber punty rod doors are a full two inches thick to help retain heat. Rare-earth magnets hold the doors in the open and closed positions.

Adjustable rod rest

You can adjust the rod rest, which is positioned in front of the punty rod doors, with wing bolts. Adjust it horizontally and vertically without tools. Or remove the rod rest altogether when you don’t need it.

Durable 3” thick insulating firebricks; side elements

The insulating firebricks, wrapped in heavy-gauge steel, soak up heat for slow, efficient cooling. The firebricks are 3” thick, 20% thicker than the standard 2 1/2” bricks, throughout the top, walls, bottom, and door. The heating elements are protected in dropped, recessed wall grooves for trouble-free firing. Wires are fastened to the elements with heat-dissipating connectors refined and proven over many years in Paragon kilns. Elements are coiled from the finest high-temperature wire available. The F-500 has no roof elements.

Custom voltage

We can manufacture your F-500 kiln for your specific voltage/phase requirements.. We will contact you after your purchase to confirm requirements.

Heavy duty components

Costly heavy-gauge nickel-plated copper wiring is covered with high temperature glass-braided insulation. The thermocouple, which senses temperature inside the kiln, is protected with a high-nickel stainless steel sheath for long life. The built-in base stays cool even during extended hold times.

Industrial grade solid state relay

The relay is industrial grade and heavy-duty for extra long life. Glass artists cherish the dependability of the solid state relay.
