Caldera-E Extension Collar for Enameling (Free Shipping)

by Paragon Industries, Inc.

Uses:  Enameling   


The Caldera-E collar stacks onto the modular Caldera or Caldera-S, adding 6 3/4” of height to the kiln. The Caldera-E collar has a 7 ½” x 4” copper enameling door on the side. Now you can explore the exciting art of copper enameling without having to buy a front-loading enameling kiln. The door is large enough for small enameling pieces such as pendants. The collar ships with a rare earth magnet to hold the enameling door open, and a stainless steel bead mandrel holder. The mandrel holder attaches to the front of the kiln.

1500 F maximum temperature

The Caldera-E collar has no heating elements. For this reason, the Caldera-E collar will slow down the firing rate of the Caldera and Caldera-S and reduce the maximum temperature to 1500°F (815°C). The collar is made of 2 ½” thick hand-selected insulating refractory firebricks. The firebricks, wrapped in heavy-gauge stainless steel, store heat for minimal heat loss after opening the door to remove a copper piece.

Rugged construction

To strengthen the firing chamber, 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. Rugged construction makes this kiln a real workhorse. For each maintenance, the stainless steel case includes case tighteners.
