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.
Optional colors at no extra charge
Brighten your studio with color! Order your kiln in one of our standard colors at no extra charge . . . berry, black, blue, hot pink, jade, navy, purple, or turquoise. Scroll down to see color samples in the options section.
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.

Sentinel Controller optional on new kilns with a Sentry Controller
This kiln can be ordered with the optional Sentinel Smart Touch controller instead of the standard Sentry 2.0 12-key controller. The upgrade price is only for a Sentinel ordered with a new kiln. The Sentinel is available as an option on any Paragon kiln that comes with the 12-key Sentry controller.
The new controller is made by Bartlett Instruments of Fort Madison, Iowa. New Paragon kilns equipped with the Sentinel give a continuous amperage and circuit voltage readout during firings. This is to inform the kiln user of voltage drops during times of heavy electrical demand, such as hot summers. The amperage reading indicates when the elements are beginning to wear.
Ramp-Hold programs can have a customized program title, which is entered through a touch screen. Store 12 custom programs with up to 32 segments per program. The Sentinel includes Novice Mode, which adds questions to guide you during programming. The controller can be updated through WiFi. View the progress of a firing in graph mode. The firing schedule can be edited during firing with Skip Step, Add Segments, Add Temperature, and Add Time. The Sentinel can turn a kiln vent or gas injection flow meter on or off for each segment of a program.21in High Stand with Casters

Shipping Weight: 177.00 Lbs. ( 80.29 Kg.) Orton Ventmaster, Installed
KILNVENT MASTER 120V M9 VENT MASTER, Installed (on large 4-sided kilns) The patented Orton Vent Master not only vents fumes but also improves firing results. At this price, the vent is factory-installed onto the back of the kiln.
It pulls fresh oxygen into the kiln for brighter colors, especially noticeable with red and orange glazes and decals. Fire red and green glazes in the same load without glaze contamination. The Vent Master draws air from the kiln, dilutes it with room air, and pushes it outdoors through a vent hose.
The extra oxygen and increased air movement help burn carbon out of the clay, which helps eliminate a host of firing problems: bloating, dark patches in the clay, porcelain mildew, pinholes, pitting, blisters, and bubbles.
The Vent Master removes fumes containing volatile metals, fluorides and sulphur oxides. You can fire even lusters, decals, metallics, and pate-de-verre glass without strong odor.
The flow of fresh air helps even out the temperature throughout the kiln. The vent also extends the life of the Kiln Sitter tube assembly, since fumes by-pass the tube. You will enjoy the convenience of the Vent Master. Throughout the firing, keep the lid closed and peephole plugs inserted. You no longer need to remember to lower the hot lid from vented position.
The Vent Master increases firing time by about five minutes for firings up to cone 4; 12 minutes for firings from cone 4 to 10. It has little effect on maximum temperature. At 132 watts, electrical consumption of the Vent Master motor is only pennies per firing.
From the shut-off temperature down to 1000°F, the Vent Master has little effect on cooling time. From 1000°F to room temperature, it reduces cooling time by about two hours.
As with Paragon kilns, the Orton Vent Master can be made for any electrical system in the world. Approved for use in the 1992 Uniform Mechanical Code. UL/CSA approved for UL Listed kilns. ETL Listed, CE Certified. Two year limited warranty.
The Vent Master requires a separate 120 volt wall plug unless your kiln is equipped with the AOP vent. (Vents that plug into the AOP of a 208 or 240 volt kiln must be the same voltage as the kiln.)
A 3’ long 2” duct comes with each vent. The 2” duct runs between the collection cup and the blower motor. Use 4” aluminum dryer duct or 4” PVC pipe between the motor and the vent outlet. (Do not use vinyl dryer duct.)
Since the vent motor is away from the kiln, there is no vibration in the kiln, the motor is kept away from the heat of the kiln, and the fan is easy to clean. The Vent Master works with all Paragon kilns except the smallest tabletop models. The Vent Master can vent two kilns. For the second kiln, order the Vent Master Expansion Kit.2x2 Glass Viewing Window
Watch the bright red kiln interior through the optional 2” x 2” high-temperature glass window, which is rated to 2300°F. This is especially convenient for glass fusing. Watch your glass treasures progress through every stage from tack fuse to full fuse. (Note: always wear firing safety glasses when viewing the kiln interior.)
This price is for an optional glass window ordered with a new kiln.Mercury Relay Upgrade TF-26
Order your new kiln with the factory installed mercury relay upgrade. The mercury relay is quiet and reliable. The life of a mercury relay has been measured in millions of on/off cycles. Mercury relays outlast the standard mechanical relays and are available as an option on new kilns. Ceramic Fiber Top with Embedded Elements
This kiln can be ordered with an optional ceramic fiber top to replace the firebrick top. (Please note that the price shown here is for a factory-installed optional lid on a new kiln.) The elements are embedded into the ceramic fiber. This eliminates element pins. This design has been proven for several years in the Bullseye factory. Lid or Door Safety Switch
The optional lid or door safety switch turns off power to the heating elements when the lid is raised or door is opened. The controller remains powered. The switch turns the power to the elements back on when the lid is closed. The switch mounts to the back of the lid or front of the door. IMPORTANT: The lid or door safety switch is required in some areas such as Canada and Europe. PC Control Port for Sentry 2
RS232 PORT ON SENTRY 2 CONTROLLERS (PC CONTROL) The RS232 is a computer port mounted to the kiln. You can monitor the kiln from a computer and store a record of each firing on your hard drive. Print graphs of firings.

Kiln Shipping Information
The most important thing to remember is that almost all kilns ship for FREE to the contiguous United States. If you need a kiln shipped outside of the lower 48 please contact us by phone at 314-963-0180 or email firstname.lastname@example.org to obtain a freight quote.
You probably realize that kilns can be very heavy and you may be nervous about ordering one online and having it shipped, but we will help you make the process smooth and easy.
Most kilns ship on a truck rather than by UPS, but don't worry, because just like a UPS shipment we handle all the paperwork and logistics.
Receiving a Kiln
Kilns are shipped on wooden pallets or crated in wooden boxes and delivery by a trucking company does not include unpacking the kiln, moving it into your building or hauling away any packing materials. If your kiln is being delivered to a residential location or a location without a loading dock we will request a lift gate so the kiln can be removed from the truck and placed on level ground. When the truck arrives the driver will unload the kiln and move it on the pallet or crate to a location near the truck. Most drivers are accommodating and will place the kiln in a reasonable location at your request BUT trucking companies are only required to unload the kiln from their truck so you should have a plan in place to move it to the final location. All kilns come with instructions on how to unpack and move your new kiln. For residential deliveries freight companies will schedule a delivery window with you in advance so you can be prepared to move your kiln to the final location.
Kiln Inspection and Damage
- It is YOUR responsibility to inspect merchandise prior to the delivery agent's departure. Inspecting your shipment includes checking for missing items as well as looking for damage to the items and the packaging. We have a signed BOL (Bill of Lading) stating that the shipment left our warehouse complete and in good condition so it is critical you inspect BEFORE signing for receipt. If you sign the receipt without a note indicating damage and/or missing items it is VIRTUALLY IMPOSSIBLE for us to file a claim on your behalf.
- If the merchandise OR packaging appears to be damaged in any way, please note the damage on the freight bill and retain a copy (a photo of the paperwork is fine). This will aid in the return/replacement process. In the case of damage you may refuse the delivery. If you do this you must contact us immediately so we can work with the carrier to resolve the issue.
- If damage is discovered after the driver has left, contact us IMMEDIATELY. If you do not contact us within 5 days damage claims CANNOT be made with the carrier and you will be responsible for repair costs. As long as damage is reported to us within 5 days we can file a claim to get it repaired. For this reason it is critical you open and inspect all freight deliveries before the window closes.
When you buy a kiln from Krueger Pottery Supply and you live within 150 miles of our location in St. Louis or staff typically delivers your kiln on one of our delivery trucks. Our staff will unpack your kiln and set it up in your building. We are not licensed electricians so we cannot do any electrical work on your home or businesses electrical system to install a kiln. Consult a qualified electrician to have a circuit run or check your existing configuration. We will also haul away all trash and packaging at your request. Cardboard and packaging are recycled if at all possible.
