Paragon has introduced the Trifecta glass blower's kiln, designed for glass blowers who make custom glass colours, blown vessels and neon tubing. According to the company, the kiln holds three crucibles, which are accessed through nine-inch holes in the lid. The three crucible holes each include a firebrick crucible cover with a wooden handle. The lid, which does not have a hinge, is held in place with four T-handle spring latches and four hand lifts are mounted to the lid. The three-inch thick, K-25 insulating refractory firebrick walls are wrapped with a ceramic fibre blanket between the firebricks and stainless steel case. As with the wall bricks, the K-25 firebrick lid and bottom are three inches thick. The crucibles can be viewed through the tapered peephole in the side of the kiln. An S-Type platinum thermocouple and a mercury relay are standard on the Trifecta kiln. After receiving a signal from the digital controller, the relay sends power to the heating elements. The separate bottom section is held in place with four T-handle spring latches, therefore should a crucible crack during firing and leak glass onto the firebrick bottom, the bottom section can be quickly replaced.
