Product Overview
Paragon Caldera-E Extension Collar for Enameling
The Paragon Caldera E Collar is a specialized expansion ring designed to increase the height of your Paragon Caldera kiln, specifically for annealing, glass fusing, ceramics, metal clay, and vitrigraph work. This collar adds extra vertical space to accommodate taller pieces or specialty setups, such as vitrigraph crucibles. Made from durable, high-temperature firebrick, the Caldera E Collar integrates seamlessly with the kiln body and lid, maintaining excellent heat retention and structural integrity. Ideal for artists and studios looking to expand their kiln's firing capabilities with flexibility and reliability.
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.
