Paragon Caldera Bead Collar Drop Ship Item.

Paragon Caldera Bead Collar Kiln Attachment

The basic Caldera is part of a kiln expansion system. When you are ready to anneal glass beads, add the modular Caldera-BC collar. It is a kiln section that stacks onto the main Caldera or Caldera-S kiln base. The Caldera-BC collar has a 7 ½” x 2” door on the side for annealing glass beads. The collar includes a brushed stainless steel mandrel holder. Insert the mandrels into the kiln. The bead door stays partially open while the glass anneals. The kiln ships with a rare earth magnet to hold the bead door open. The Caldera-BC collar adds 4 ½” of height to the main kiln. The collar has no heating elements. The Caldera and Caldera-S, with a collar, still fire to 2000°F/1093°C. The Collar is made of 2 ½” thick hand-selected insulating refractory firebricks. The insulating firebricks, wrapped in heavy-gauge stainless steel, soak up heat for slow, efficient cooling. 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 little workhorse. For easy maintenance, the stainless steel case includes case tighteners. The Caldera-BC is made in Mesquite, Texas USA by skilled craftspeople. Add a bead collar for annealing lampworked beads. With a hinged 7.5" x 2.25" (191 x 57mm) door, it adds 4.5" (114mm) of height to the kiln. Measures 13" x 13" x 4.5" (330 x 330 x 114mm). Max Temperature: 2000 Degrees F Shipping Dims: 8.5 x 16.5 x 16.5 in. (22 x 42 x 42cm) Shipping Weight: 14 Lbs. (6.35 kg.)
