Mesquite, TX (PressExposure) November 17, 2011 -- Paragon Industries, the kiln factory in Mesquite, Texas, has just introduced the Darby Dipper crucible furnace (also called a kiln). It is designed for glass blowers who need a small, 120 volt kiln for making custom glass colors, blown vessels, and neon tubing. The kiln can also be ordered in 240 volts and for international electrical systems.
The Darby Dipper is made from 3" insulating firebricks and has extra ceramic fiber blanket insulation behind the walls. The kiln, or furnace, is equipped with a Sentry Xpress digital temperature controller and an S-Type platinum thermocouple. The digital controller mounts on the wall and is connected to the Darby Dipper with 6' cables.
The Sentry Xpress digital controller can be programmed with up to 8 segments, or sections. The controller stores 4 programs. It can also operate in the simplified Single Segment mode, which is firing to one specific speed and temperature. The controller is made by the Orton Ceramic Foundation for Paragon Industries.
The controller includes a delay time, temperature alarm, program review, thermocouple offset, and various error messages that report mechanical problems.
Access to the crucible is gained through a 6" hole in the firebrick top. (The top is mounted without a hinge so that it can be replaced easily.) The kiln includes a firebrick cover with handle to place over the 6" hole. Sidewall heating elements are protected in dropped, recessed firebrick grooves. Paragon invented this type of groove several decades ago. The stainless steel case can be adjusted with case tighteners mounted to the side of the kiln.
"Paragon was founded by Frances Darby," said Arnold Howard, spokesman for Paragon. "She would be amused by the name Darby Dipper. This is the first time we have named a product after her." Frances Darby founded Paragon in 1948. The kiln factory is a few miles east of Dallas, Texas.
