In the veryhigh temperature furnace two piles offlat carbon plates are employed, one pileon each side of the chamber. The application of the electric furnacecovers many fields, such as enamelingwatch dials, hardening steel, temperingtools and dies, aiding in food analysisin laboratories, testing minerals at mines,etc. v.
