Caldera-BC Bead Annealing Collar

The Caldera-BC collar is a kiln section that stacks onto the Caldera or Caldera-S kiln. The Caldera-BC collar has a 7½” x 2” door on the side for annealing glass beads. The Caldera-BC collar adds 4 ½” of height to the kiln. The collar has no heating elements. The Collar is made of 2 ½” insulating refractory firebricks.

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.

Imagine the glass you could make with this kiln: Sag, slump, and fuse. Make small bowls, pendants, earrings, cufflinks, and even bracelets. Enjoy the glittering beauty of dichroics. This kiln will give you a haven of creative enjoyment that you will especially appreciate when life gets hectic.

***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.

The Caldera-BC can ship by UPS. Enjoy lower shipping cost and faster service. Specially designed cartons and foam padding assure that the kiln will arrive safely.

This is a must have for anyone who needs lots of access to the kiln during the session. I personally open my kilnd 50 or more times heating rods and putting in and pulling out beads and gauges so for me this part is a must have! The magnet that comes with it, well I dont know what its for, wont hold the door open but if you set it just right it will hold it closed this way you can get close to max temp with the bead ring on. Door size, I have no complaints about this, could be bigger I guess but there has to be a medium between door size and heat escaping so this is good enough. Its nice and thick so it holds heat nicely.

Must have if you own caldera

If your a lampworking/bead worker with a caldera then you NEED THIS! Mainly for the door which is a good size. But it doubles your kiln in height. But honestly I own a FIREFLY NOT A CALDERA and I just took my lid of its hinge and turned it into a table top. And the middle stack fits great!
