A true workhorse
I lovelovelovethe Caldera . I not only fuse glass and work in metal clay,but I teach a lot of classes,so I’m firingthe kiln all the time . It is a true workhorse . In three years I have not had one problem with it . I have done drop ring vases,small pot melts,small dishes,and candleholders in it . It is inexpensive to run on 120 volts . –Lisel Crowley

This kiln will give you a haven of creative enjoyment that you will especially appreciate when life gets hectic . You will soon find that glass fusing is addictive .
The joy of testing
You will never outgrow a small kiln . If you later buy a larger one,you can continue to use the small one for testing and small projects . Perfect a new design in the small kiln before running production quantities in the large kiln . A small test kiln is invaluable in solving ceramic glaze problems and perfecting difficult glazes such as crystallines .
The Caldera in the classroom
A Caldera is a nice addition to school programs . A test kiln is relatively inexpensive . Students can make gifts in the Caldera 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 kiln load of ware have been ruined because they were fired to the wrong temperature . With a Caldera kiln,you can easily test unlabeled clay .
Strong lap joints
To strengthen the firingchamber,the firebrick corners are fitted together with L-shaped notches . This type of joint lasts longer than the butted joint and the picture frame mitered joint found on competitive brands . The base is versatile and can be flipped if one side is damaged . The lid and base are interchangeable unless you order the lid with a glass window .
This kiln is built to last . Elements are coiled from the finest high-temperature wire available . They use heat-dissipating element connectors refined and proven over many years in Paragon kilns .

The optional glass window
You can order your Caldera with an optional glass window in the top . The glass window is rated to 2300℉ (1260℃),so it can easily withstand glass fusing temperatures . Please note,however,that the window reduces the kiln's maximum temperature to approximately 2100℉ (1148℃) and is meant for glass fusing . (You can still fire porcelain and stoneware jewelry even with the window,but you will need to plug the window with ceramic fiber .)
The basic Caldera is part of a kiln expansion system . Add a collar for annealing glass beads or enameling small copper pieces . Add 4½of height to the Caldera with a Caldera-BC collar,which has a 7½x 2 door on the side for annealing glass beads . The Caldera-X is the same type of collar,but without the bead door . Explore copper enameling with the 6 3/4 tall Caldera-E collar .

Warning for the caldera kiln equipped with a lid safety switch and collar
The Caldera kiln was intended to be a stackable kiln with a separate lid and bottom . However,the lid must be hinged to the Caldera body when a lid safety switch is installed . To stabilize a Caldera kiln that has a hinged lid,we attach the kiln body and kiln bottom together with two latches .
If an unlatched collar (enameling,bead,or extension) is mounted between the Caldera body and the kiln bottom,care must be taken when opening the hinged lid . Do not open the lid past 90 degrees (where the lid is straight up) unless the lid leans against a heat-proof support behind the kiln .
Please be aware when firingthe Caldera with any collar in place,the maximum temperature is reduced . Enameling Collar−1800℉; Bead Collar−2000℉; Extension Collar−1700℉
The Caldera can ship by UPS/FedEx for lower shipping cost and faster service . Specially designed cartons and foam padding assure that the kiln will arrive safely . Save the box and foam packing inserts so you can conveniently move the kiln while on vacation or to seminars . Unstack and loadthe kiln sections in minutes .
