<p>The present invention provides a method for manufacturing a glass substrate. When molten glass generated by glass raw materials are shaped to manufacture a glass substrate, metal impurities such as platinum alloy are hard to contain in the glass substrate. The method for manufacturing the glass substrate comprises a process of melting the glass raw materials in a melting furnace so as to manufacture the molten glass; a process of clarifying the molten glass; and a process of shaping the classified molten glass by a shaping device so as to form the glass substrate. Furthermore, before manufacturing the molten glass, the manufacturing method also comprises a process of pre-heating at least one part of a flow path forming component formed by platinum or platinum alloy to be close to the temperature for operating the glass substrate. During the pre-heating, inert gases circulate in the flow path of the molten glass, and the flow path forming component is used for forming the flow paths of the molten glass between the melting furnace and the shaping device.</p> |
