A small pyrometric cone placed in the Auto-Cone bends to maturity and turns off the kiln. (A pyrometric cone is a small pyramid of clay that bends when the ware has received the proper amount of heat work. Cones and ceramic materials are rated by cone number.)
Note: Please monitor the kiln during firing and check it near the expected shutoff time. Do not completely depend on any shutoff device, mechanical or electronic.
Built to Last
The firebrick corners of the Caldera XL-KS are fitted together with L-shaped notches for extra strength. This type of joint lasts longer than the butted joint and the "picture frame" mitered joint found on competitive brands.
The inner and outer lid surfaces and the top rim of sidewall firebricks are hardened and sealed with a refractory coating that protects the ware from dust. The firing chamber, including the lid and bottom, is made of 3” thick firebricks, 20% thicker than standard 2 1/2” bricks. A heavy steel base supports the brick bottom. No extra stand is needed.
We make the heating elements from the finest high-temperature wire available. Paragon uses heat-dissipating barrel-shaped element connectors refined and proven over many years in our kilns. The stainless steel case and lid band include case tighteners for easy maintenance.
The Caldera XL-KS control box is painted with a durable high temperature, water-base finish. We use water-base paint because of the low emissions during spraying. This creates a safer working environment for our employees and cuts down on pollution.
The Caldera XL-KS can ship by UPS. Enjoy a lower shipping cost and faster service. Specially designed cartons and foam padding assure that the kiln will arrive safely.
The heat of the kiln offers wonderful surprises. Glazes undergo a complete transformation in the kiln. Opening a kiln to view your masterpieces is a joy you will never outgrow. Get your family involved and create priceless memories using your kiln.
The Furniture Kit
The furniture kit consists of carefully selected fireclay shelves and posts for the Caldera XL or Caldera XL-KS. When estimating the price of the kiln, include the cost of furniture. The furniture allows you to stack multiple layers of ware. Without it, you could fire only the ware that would fit on the kiln bottom.
