|At no extra charge you can order your new kiln in one of the custom colors below instead of the standard blue or black! |
Please note: colors may vary slightly.
If you have difficulty loading deep kilns, we recommend the 22 ¼” deep TnF-23-3. If you need extra firing capacity in a short kiln, consider the 12-sided TnF-27-3.
During busy seasons when orders are backlogged, you will be grateful you own a dependable Paragon kiln such as the TnF-23-3. Studio owners call these kilns “real work horses.”
Paragon studio kilns have withstood years of abuse in school environments. High school ceramics teachers fire these kilns unmercifully, without remorse. Yet the kilns keep going. People swear by them.
The 10-sided TnF-23-3 comes in deluxe 3” thick sidewalls, lid and bottom. This is 20% thicker than the standard 2 ½” thick bricks. Since the TnF-23-3 is designed to fire porcelain and stoneware, it will easily handle low-fire ware.
The massive lid is easy to lift with Paragon's patented “LiteLid,” which does away with cumbersome pulleys and cords and reduces lid weight to only several pounds of pressure. Most people can lift the lid with one hand. Unlike pulleys and weights, the LiteLid is self-contained on the kiln. No need to drill holes in the ceiling for pulleys. The LiteLid sharply reduces wear between the lid and top rim of firebrick. The truss and floating lid allow expansion of the lid. Ask competitors if their lid spring includes a truss and floating lid.
This kiln features a top row of 2” high blank wall bricks. Since the brick is without element grooves, it is less susceptible to damage during loading than a grooved brick.
The 24” wide stand for 10 & 12-sided kilns supports the brick bottom with framing that is 4 ½” wide across the top of each side. The stand accommodates the Orton KilnVent. The stand is rock-steady, with 16-gauge frame and heavy 12-gauge legs.
If you move your TnF-23-3 kiln out of the way when not in use, order an optional deluxe kiln stand with steel casters.
Something to consider if you already own a 12-sided kiln: Why purchase a 10-sided kiln such as the TnF-23-3 when you produce enough ware to fill a 12-sided kiln? It is because some ware fires more efficiently in a 10-sided kiln. Example: 10- and 12-sided kilns both fire four 10” wide bowls per shelf. When you own both sizes of kilns, you can choose the most efficient kiln for each size of ware. The 10-sided kiln is a good choice for those whose production depends on short firing cycles. Since 10-sided kilns are smaller than 12-sided, they can heat and cool faster. The 10-sided shelves are lighter than the 12-sided, and easier to lift.
A heavy galvanized steel base covers the reversible brick bottom completely. It folds up under the stainless case on all sides to strengthen the firing chamber. This is one more assurance that your Paragon kiln is built to last.
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.
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. Learn to conserve energy by experimenting with firing speed, load density, etc.

Options and Accessories
The furniture kit consists of carefully selected fireclay shelves and posts for this particular model. When estimating the price of the kiln, include the cost of furniture. The furniture allows you to stack multiple layers of ware. Without it, you could fire only the ware that would fit on the kiln bottom.

3-Zone ControlType K Thermocouples
Improve temperature uniformity. The standard digital Paragon kiln is single zone; 3-zone is a factory-installed option that controls temperature from 3 separate locations in the kiln. 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.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. Orton Ventmaster, Not Installed KILNVENT MASTER 120V M9 VENT MASTER (Installed after the kiln is set up) The patented Orton Vent Master not only vents fumes but also improves firing results.
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 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.
Order a kiln with the Vent Master and we will drill all necessary holes at no extra charge. (Please note: kilns in stock will not be uncrated to drill the holes.) The holes are only ¼”.
The Vent Master requires a separate 120 volt wall plug unless your kiln is equipped with the AOP vent.
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.)
Position the Vent Master next to the kiln and attach the collection cup to the bottom or side of the kiln. The collection cup fits under most top-loading kilns. (Note: The kiln stand must be at least 5” high to accommodate the collection cup.) 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.Auxiliary Port for Orton Vent-Master
AUXILLARY OUTPUT FOR SENTRY II CONTROLLERS (VENT CONTROL) The AOP (Auxiliary Output) is an electrical outlet mounted to the kiln. Plug either a downdraft vent or an external alarm into the AOP. Control the vent with Cone-Fire or Ramp-Hold modes. 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. FREE Deluxe 24 inch Rolling Stand
Paragon 7-, 8-, 10-, and 12-sided top-loading ceramic and glass kilns now come with a deluxe rolling stand at no extra charge. The new stand has locking casters, a mounting bracket for the Orton Kiln Vent, and a greenware drying rack. You will enjoy the convenience of effortlessly moving the kiln out of the way when not in use.
The ceramic kiln deluxe stands are 12” high, and the glass kiln deluxe stands are 18” high. The stands include assembly instructions. The deluxe stand replaces the discontinued standard kiln stand.
The discontinued stands had four legs, four horizontal side pieces across the top, and plastic feet. The new stand has two side frames, two shelves, and four locking casters. The Ovation oval kilns will receive two stands per kiln.
The new stands slide together with slots that line up the screw holes. To install an Orton Kiln Vent, slide the collection cup into the vent bracket. The new stand eliminates the need for the collection cup mounting bolt.
Take advantage of the heat that radiates from the kiln. Load greenware on the lower shelf. Heat from the kiln will dry the ware and prepare it for the next firing. Save the time and expense of drying the ware inside the kiln. Type S Thermocouple Upgrade for Single Zone
Optional Type-S premium-grade thermocouple for single-zone 2 1/2" - 3" wall kilns. Ideal for firings above cone 4. It is extremely long lasting even at stoneware temperatures. (This price is for the thermocouple that is factory-installed on your new kiln.) Mercury Relay Upgrade TF-15
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.

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 email@example.com 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.
