Thisinner compartment con-tains the electrodes for thearcs (indicated in Fig. 2 incross-section by small cir-cles.) The glass-making materials drop down through the arcs, and are acted upon bythe same. Sand is fed into the furnace through the hopper atthe top and passes downward through the flue. Just before itreaches a vertical passage, fluxes, lime, etc., are fed through thehoppers, specially provided for this purpose, as shown in theillustration. The mixture then drops downward through the. FIG. 2.—GLASS furnace. KLKC I KtH AND METAI .1 .lK(liCAL INDUSTRY. [Vol. III. No. lo. arcs.
