The new and improved F-240.
We have added major upgrades to three of our lamp working kilns; the prices remain the same. You, the lamp worker, asked for these changes, and we listened.
New thicker firebricks
We increased the firebrick wall thickness of the F-130, F-240, and F-500 by 20%. These kilns now have 3” thick firebricks throughout their firing chambers. The extra insulation enables the kilns to maintain long temperature holds with greater ease.
The deluxe mercury relay
Of these three models, the F-500 was the only kiln that previously came standard with a mercury relay, which controls the cycling of the heating elements. Now the F-130 and F-240 also have a mercury relay. The relay is industrial grade and heavy-duty.
Improved mandrel holder
The F-500 has had a slide-out mandrel holder for two years. We just added that to the F-130 and F-240. The mandrel holder on these kilns can be adjusted horizontally and vertically without tools. Pull out the heavy-duty mandrel holder (also called a point rest) until it is exactly where you need it. The holder slides inside steel tubes, which are hidden in the base of the kiln.
Sidewall heating elements
Previously the F-130 and F-240 could be special-ordered with sidewall elements; they came standard with the F-500. Now these models all have sidewall elements instead of top elements.
The elements heat from the sides and back in dropped, recessed wall grooves, which protect the elements. But if you prefer, you can still order these kilns with elements in the top instead of the walls; the price of the kiln is the same.
We recommend that you order the optional safety door switch, which turns off the elements when the door is raised. (The temperature controller will continue to operate when the safety switch turns off the elements.)
