Paragon Kiln - GL24ADTSD

Deluxe Mercury Relays or Optional Swapped Solid State Relays

The GL-24ADTSD includes features not found on competitive kilns. For instance, for your peace of mind, mercury relays are standard on this kiln. Relays send power to the elements on command from the digital controller. Mercury relays found on the GL-24ADTSD are industrial-grade and far outlast mechanical relays. The life of the quiet, reliable mercury relay has been measured in millions of on/off cycles.

Elements in the Top, Walls, and Door

The GL-24ADTSD digital kiln heats from the top, three sides, and door for unsurpassed heat distribution. It is 15” high inside with room to bend glass for curved windows or cabinet doors and to repair lampshades. Make huge glass-fused platters. Crack the door to drag a rod across the softened glass or to emboss designs in the surface. Explore small-to-medium sized casting and pâte de verre. Enjoy the glittering beauty of dichroics. Make treasured gifts.

The GL-series lid elements use an element groove that eliminates element pins. The element coils are wider than the groove opening, so the elements stay in place without pins. The elements in the walls are seated and protected in dropped, recessed grooves.

Use the kiln’s side heat for taller projects such as drop-out vases sagged through a ring mold. Side elements span the three walls in six horizontal rows.

The kiln’s door elements offer unsurpassed heat distribution for difficult pieces. (The door, with elements, is always hinged on the right side.)

Adjust the Ratio of Heat Between the Top and Walls

The kiln uses advanced power ratio technology, pioneered by Paragon, to balance the heat between the top and side/door elements. Program the digital controller to balance the heat between the top and sides in increments of 10%. (i.e., 100% top - 0% sides, 50% top - 50% sides, 80% top – 20% sides, etc.) Set the heat balance for any combination desired between the top and sides so that the total heat output equals 100%. Imagine the precise control you will have in adjusting the kiln to slump glass or to improve heat distribution over large fused panels.

Heavy Duty Construction

Paragon’s GL-series are made for years of rigorous firing, as artists all over America can attest. The insulating firebrick, wrapped in heavy-gauge steel, soak up heat for slow, efficient cooling. A double heat shield and air gap between the kiln and ventilated switch box help keep electrical components cool for long, trouble-free service. Costly, heavy-gauge nickel-plated copper wiring is covered with high-temperature glass-braided insulation.

Accurate Thermocouple

The thermocouple senses temperature inside the kiln. It is the small rod that extends into the side of the firing chamber. The GL-24ADTSD comes with a ¼” wide Type-K, 14-gauge, exposed-tip thermocouple made with special-limit wire for superior accuracy. The new and improved thermocouple replaces our earlier sheathed thermocouple. The new thermocouple is made in America to our exacting standards.

Spring-Loaded Door Latches

The spring-pressure latch and a ½" recess around the edge of the firebrick door keep the door tightly closed. The door remains rock-steady on a heavy hinge shaft. Four hand lifts aid moving. The base is open in the back and slotted to dissipate heat.

Peepholes

Watch the red-hot glass through two tapered peepholes, drilled one above the other in the wall opposite the switch box. Peephole plugs are included. (The optional glass viewing windows are not available on the GL-24ADTSD because of the heating elements in the door.)
