The electric melting technology is an efficiency and clean technology, and the all-electric melting furnaces can be used for production of various kinds of glass. The structural and process characteristics of all-electric melting furnaces were summarized. The "oxidation/reduction" chemical reactions of glass raw materials during high-temperature melting were introduced, and the impact of several elements in raw materials at high temperatures chemical reactions were analyzed. Finally, it is recommended that all-electric melting furnaces can be adopted when producing special glass.
