Paragon GL-18AD Glass Fusing Kiln
Create breathtaking glass in the deluxe GL-18AD Professional Series glass kiln. The GL-18AD is proudly made in America by skilled workers and is designed for those whose livelihood depends on glass production.
An Endless Variety of Glass Projects
Imagine the glass you could sag, slump, and fuse with this kiln. Make small bowls, pendants, earrings, cufflinks, and even bracelets. Enjoy the glittering beauty of dichroics. Make treasured gifts. When you own a Paragon kiln, you can experiment with new glass ideas to your heart’s content.
Becky Johnson, a glass teacher in Dallas, Texas, describes the excitement of a kiln: “I like to open the kiln with my students so that we can review and admire each other’s treasures together. The transformation of the glass inside the kiln is magical and mystical. It changes from pieces of arranged cut glass to awe-inspiring art. To be some part of that process is a true gift.”
The GL-18AD digital kiln is 13” high inside with room to bend glass for curved windows or cabinet doors and to repair lampshades. Make glass-fused platters. Crack the door to rake or emboss designs in the surface. Make small-to-medium sized castings and pâte de verre.
Engineered for Reliability
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 of the glass. 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. The thermocouple, which senses temperature inside the kiln, is protected with a high-nickel stainless steel sheath for long life.
Dual Mechanical Relays
The GL-18AD has dual mechanical relays for extra reliability. They send power to the elements on command from the digital controller. Two relays last longer than the single relay of competitive kilns because of the reduced amperage going through each relay.
Optional Deluxe Mercury Relays
Relays turn on the kiln’s heating elements. Order your new kiln with the quiet, reliable mercury relay instead of the standard mechanical relays. The life of a mercury relay has been measured in millions of on/off cycles. The mercury relay far outlasts the standard mechanical relays and is optional on the GL-18AD.
Pinless Element Groove
The GL-series lid elements are mounted in pinless element grooves. Pins are unnecessary because the element coils are wider than the groove opening. Wires are fastened to the elements with heat-dissipating connectors refined and proven over many years in Paragon kilns.
The spring-pressure door 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.
Watch the red-hot glass through two tapered peepholes, drilled one above the other in the wall opposite the switch box. The peepholes are hardened and sealed with a special refractory coating to help protect the glass from dust. Peephole plugs are included. (Most GL-18 models are drilled for peepholes. However, some international models have no peepholes. If you are outside the U.S. and you want peepholes, please specify them at the time that you order the kiln.
You can also order an optional 2” x 2” glass window for your kiln. The window is rated to 2300°F (1260°C), so it can easily withstand glass fusing temperatures.
The Convenience of Digital Firing
You will be amazed at the convenience of digital firing. The reliable solid-state Sentry controller continually monitors the firing so you can spend your time productively without closely watching the kiln. (Please remember, however, to check the kiln during firing and to monitor it near the expected shutoff time.) The sealed touch pad keeps out dust and is easy to wipe clean.
Paragon’s innovative controller will help you achieve consistent results from one firing to the next. The controller has powerful features that you will enjoy using. Yet we have also worked hard to make the controller user-friendly.
Do you ever wonder how much electricity your kiln uses? The digital controller can figure this for you with the press of a button. Find out how little a kiln actually costs to fire.
The electronic circuit board can be removed in minutes for upgrade or repair. The board is the heart of the digital kiln and is small enough to fit in the palm of your hand.
Water Base Paint
The GL-18AD has a durable high temperature, water-base finish. We chose water-base paint because of the low emissions during spraying. This creates a safer working environment for our employees and cuts down on pollution.
Optional Ceramic Fiber Top
The standard GL-series kiln comes with an insulating firebrick top, grooved for heating elements. The upgrade option is a ceramic fiber top with element grooves. The fiber top helps keep the glass clean during firing.
Optional Kiln Stand
The heavy-duty GL-series stand raises your GL-18, GL-22 or GL-24 kiln to a convenient working height. Begin operating your new kiln without having to find a table strong enough to support 250 pounds. The table is 147 pounds of rock solid construction.
At Paragon, phone calls that we receive during business hours are answered by a live person at the factory. We are here to help you long after the sale should you ever need it.
And, of course, Paragon kilns are made in America by highly skilled workers. Fifty-one percent of them have been with Paragon for over a decade.
Designed for production
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.
