F500 Lamp Working Kiln
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.
Optional door safety switch ($70 option - add to cart)
We recommend that you order the optional safety door switch, which turns off the element when the door is raised. (The temperature controller will continue to operate when the safety switch turns off the elements.)
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 mercury relay
A mercury relay is standard on the F-500. The relay sends power to the elements on command from the digital controller. The industrial-grade mercury relay far outlasts mechanical relays. The life of the quiet, reliable mercury relay has been measured in millions of on/off cycles.
Features of the F-500
Convenient digital temperature controller
The F-500 has a user-friendly 3-key Sentry Xpress 4.0 Digital Controller which includes two firing modes: Single Speed and 8-segment Ramp-Hold. The solid-state controller continually monitors the firing so you can spend your time productively without closely watching the kiln. The sealed controller touch pad keeps out dust and is easy to wipe clean.

High temperature black finish
The F-500 is proudly made in America to exacting standards. It has a durable high temperature, water-base finish. We chose water-base paint because of the low emissions during spraying.
