You will not outgrow this small digital test 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. This digital 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 Paragon Caldera XL kiln 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 digital test 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”
The Paragon Caldera XL kiln 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 of the digital test kiln.
The Paragon Caldera XL kiln 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 Paragon Caldera XL kiln can ship by UPS. Enjoy a lower
shipping cost and faster service. Specially designed cartons and foam padding assure that the digital test 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.)
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.
Features of the Sentry Xpress 3-key Controller for Ceramic Kilns
Fire to a pyrometric cone by merely entering cone number and slow, medium, or fast speed.
Use Program Review to check the accuracy of the program you are about to fire.
Set a temperature alarm to remind yourself to close a vented lid or check the kiln at a certain temperature.
Design Ramp-Hold programs with up to 8 segments (steps).
Skip a segment in Ramp-Hold during firing.
Hold (soak) the temperature in both Cone-Fire and Ramp-Hold.
Control both heating and cooling in Ramp-Hold.
Add hold time in Ramp-Hold during firing.
Change the target temperature in Ramp-Hold during firing.
Temperature Display throughout firing and cooling in your choice of °F or °C
Thermocouple Offset adjusts the thermocouple readout.
Set the Delay to turn on the kiln later to suit your busy schedule.
Error Messages report mechanical problems such as a disconnected thermocouple, stuck relay or broken element.
LED Lights show whether you are in program, review, or firing mode.

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 OPTIONAL 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.
