The GL-24ADTSD Professional Series glass kiln.
Paragon has just released its Professional Series glass kilns. They are painted black to distinguish them from our blue ceramic, jewelry, and pottery kilns and smaller glass kilns.
The new kilns incorporate a number of subtle changes and two major ones. The larger Professional Series have mercury displacement relays, which turn on the heating elements. The relays work hard in a glass kiln, especially during the very long annealing times needed for fusing and slumping thick, large pieces. The mercury displacement relays last much longer than the mechanical type. (You can also order optional mercury relays for most of the other Paragon models.)
We are also introducing power ratio technology in our new glass kiln series. The feature comes with models that heat from the top and sidewalls. Power ratio is part of the digital temperature controller and allows the kiln owner to adjust the ratio of heat output between top and side/door elements.
The heat can be adjusted between the top and sides in increments of 10%. Power ratio eliminates the infinite switches of earlier models, so the kilns have less wiring and fewer mechanical parts. Also, the software makes the adjustment more precise than is possible with the infinite controls.
