**The Single Set Point Control allows you to set desired temperature then toggle center switch to the left for a second and release to reach preset temperature and shut off. To fire to preset temperature and hold, move the center switch right and leave it there. *Stainless steel mesh shelves are stackable on the fiber shelf and on each other and with two mesh shelves 44 square inches of firing surface is available.
A bit more about the SSP controller. You CAN use it to fire other things. It will just be a manual process. Take glass for instance. Glass is subject to "thermal shock" which simply means if you heat or cool it too quickly through its "fragile zone" of 700-1000 degrees F it is likely to break. With a SSP controller, since you can set it to "ramp" (heat up) to 700 degrees, it will fire as fast as it can to 700 and will sit at that temperature until you change the temperature. Once there you would adjust the temperature to 800 degrees F and the kiln would simply start cycling on and off until it reached 800. Then you would set it to 900 - same thing then 1000 - same thing. Once it reaches 1000 you can program in the temperature at which glass starts "moving" which is about 1350 degrees F. The you just watch the glass creation until it reaches the desired state then you change the program back to 1000 degrees and it will cool down to that temp then you set it to 800 degrees and once there just turn the kiln off. The reason you can jump to 800 from a thousand is that the kiln does have some insulating properties in that it will retain heat and lose it slowly - slowly enough not to damage the glass as it cools its way through the 1000 to 700 degree fragile zone.
