Paragon Caldera XL
Fire porcelain, stoneware, china, ceramics, and decals in Paragon’s digital Caldera XL. Test glazes and glaze application ideas before running production quantities in a large studio kiln.
You will not outgrow a small kiln even if you acquire a larger kiln later. Continue to use the Caldera XL for testing or for small projects. Carry it with you to seminars or on vacation; convenient hand lifts on the sides aid in moving the kiln.
The Caldera XL in the Classroom
A Caldera XL is a nice addition to school programs. A test kiln is relatively inexpensive. With the Caldera XL, students can make gifts in time for a birthday or holiday instead of waiting until the school’s large kiln is fired. A test kiln creates enthusiasm for a clay program. Students can test glazes while they feel the momentum instead of waiting to fire them in the large kiln.
New teachers inherit bags of unlabeled clay in their classrooms. Many loads of clay have been ruined because they were fired to the wrong temperature. With a Caldera XL kiln, you can easily test unlabeled clay.
Built to Last
The firebrick corners are fitted together with L-shaped notches for extra strength. This type of joint lasts longer than the butted joint and the "picture frame" mitered joint found on competitive brands.
The Type-K thermocouple, which reads the firing chamber temperature, is protected in a high-nickel stainless steel sheath for long life. A steel base supports the brick bottom. The Caldera XL comes with a built-in steel stand; no extra stand is needed. Use the switch on the front panel to turn off power to the controller when the kiln is idle.
Both sides of the lid and top rim of sidewall firebricks are hardened and sealed with a refractory coating to protect the ware from dust. The firing chamber, including the lid and bottom, is made of 3” thick firebricks, 20% thicker than standard 2 1/2” bricks.
The Caldera XL has dual mechanical relays for extra reliability. They turn on power to the elements after receiving a signal from the digital controller. Two relays last longer than the single relay of competitive kilns because of the reduced amperage going through each relay.
Heating elements are made from the finest high-temperature wire available. Paragon uses heat-dissipating element connectors refined and proven over many years in our kilns. The stainless steel case and lid band include case tighteners for easy maintenance.
The Caldera XL control box is painted with a durable high temperature, water-base finish. We use water-base paint because of the low emissions during spraying. This creates a safer working environment for our employees and cuts down on pollution.
The Caldera XL can ship by UPS. Enjoy a lower shipping cost and faster service. Specially designed cartons and foam padding assure that the kiln will arrive safely.
The Convenience of Digital Firing
The reliable solid-state Sentry Xpress controller continually monitors the firing so you do not need to watch it closely. (Please remember, however, to check the kiln occasionally during firing and to monitor it near the expected shutoff time.) You can try out a demonstration of the controller on your computer by clicking here. Practice using the controller before you even buy the kiln.
Paragon’s innovative controller will help you achieve consistent firing results. The user-friendly controller has powerful features that you will enjoy.
The Sentry Xpress controller fires in either Ramp-Hold or Cone-Fire mode. Control both heating and cooling with simple 3-key operation.

The heat of the kiln offers wonderful surprises. Glazes undergo a complete transformation in the kiln. Opening a kiln to view your masterpieces is a joy you will never outgrow. Get your family involved and create priceless memories using your kiln.
The Furniture Kit
The furniture kit consists of carefully selected fireclay shelves and posts for the Caldera XL or Caldera XL-KS. 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.
Made in the USA
The Caldera XL is proudly made in Mesquite, Texas by master craftspeople. Half of our factory employees have been at Paragon for at least 10 years. Phone calls during business hours are answered by a live person at the Mesquite factory. We are open from 7 a.m. to 5:30 p.m. Central Standard Time Monday through Thursday. These expanded hours allow us to serve customers in differing time zones. Call us—we would enjoy hearing from you. Our customer service representatives will be glad to help you after the sale, even long after the kiln is out of warranty, and at no charge.
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.

Options and Accessories
Recommended furniture kit for the Paragon Caldera XL, Caldera XL-KS, and equivalent sized kilns. Included:
2 - C-7 Shelves (7” x 7” square x 5/8”)
1” wide Square Posts, 4 each of - 1”, 3”, 5”
1 lb. Bag Kiln Wash
Shipping size: 12” long x 9” wide x 7” high
Ware is fired on shelves that can withstand high temperatures. The shelves are separated by posts so that you can fire multiple layers of ware in your kiln. Coat the shelves with kiln wash, which prevents glaze or glass from sticking to the shelves.
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. Sentry 12 Key Controller Upgrade
This kiln can be ordered with the optional Sentry 12-key controller instead of the standard Sentry Xpress 3-key controller. The upgrade price is only for a Sentry 12-key ordered with a new kiln.
Because you can type numbers into the 12-key Sentry, it is faster to program than the 3-key. (Numbers are programmed into the 3-key Sentry Xpress by scrolling up or down with arrow keys.)
Ramp-Hold programs are divided into segments. Each segment has a target temperature, firing rate, and, if desired, a temperature hold. Hold (soak) maintains a specific temperature. (Programs remain in storage even when the kiln is unplugged.)
Program Storage, 12-key Sentry: one 20-segment and eight 10-segment programs
Program Storage, 3-key Sentry Xpress: four custom programs, 8 segments (steps) each
General Features That are Unique to the 12-key Sentry
Firing Cost: Enter your cost of electricity and the kilowatts used by your kiln. At the end of a firing, the controller will give the cost of electricity to fire that load. Find out how little a kiln actually costs to fire. Learn to conserve energy by experimenting with firing speed, load density, etc.
AOP Vent: The “Auxiliary Output” is available on most Paragon kilns that have the 12-key Sentry. The AOP is a relay-powered electrical receptacle mounted to the kiln. You can plug an Orton Vent Master into the AOP to control when the vent operates during firing.
Stop/Back Key goes back one step with each key press during programming to correct errors.
Add Time Key adds five minutes to a temperature hold with each key press during firing. Helpful for glass with holds.
Thermocouple Selection: The 12-key Sentry can operate types K, S or R thermocouples.
Program Safety Lock for the program in active memory gives you peace of mind.

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.
