To promote recycling of an alkali-free glass, to invent a method for manufacturing a glass sheet with excellent dislvability of a glass batch, to increase recycling rate of the alkali-free glass, and to reduce production cost of a glass sheet having a high strain point.
The method for manufacturing the glass sheet comprises: blending glass raw materials and preparing the glass batch; subsequently melting the glass batch in a glass-melting furnace; and shaping the melt into the glass sheet. Here, the alkali-free glass is used as a portion of the glass raw materials. The glass raw materials are blended so that the glass sheet acquires a glass composition comprising, in mass% calculated in terms of oxides, 40-75% SiO
