ADVANCER® kiln shelves are the only silicon carbide shelves tested and recommended for use in resistance coil element kilns. At only 5/16-inch thick, ADVANCER® kiln shelves allow for significantly more stacking space when compared to conventional 5/8” and 1” thick cordierite kiln shelves. Put 6 ADVANCER® shelves in the height required for 5 cordierite shelves giving an additional 20% stacking space! At less than half the weight of conventional shelves, ADVANCER® kiln shelves are far easier to handle and lift in and out of the kiln with less stress to your hands and back.
Lower mass and faster heat transfer (greater thermal conductivity) means shorter firing cycles and reduced energy consumption.
Not only will an advanced Silicon Carbide shelf stay flat in this application, but its 5⁄16-in. thickness also allows for more stacking space and reduced energy costs. It is also easier to lift in and out of top-loading kilns due to its lighter weight. The initial investment for the shelf is significantly higher than cordierite, however, it is easy to realize a substantial return on investment when energy and productivity savings are considered.
It should be noted that there has been a long-standing belief in the pottery market that silicon carbide shelves cannot be used in electric kilns due to the risk of electrical shock.
Silicon carbide is an electrical conductor; however, the electrical resistance of advanced NSiC shelves depends on several variables, making the likelihood of an electrical shock minimal. As with any type of powered equipment, observing common sense rules, precautions and maintenance recommendations will eliminate potential hazards. For instance, advanced NSiC shelves should not be used in kilns that are in poor repair with unpinned elements protruding out of their grooves, and an operator should never reach into an electric kiln unless the power is turned off.
