| titleOfInvention | Method for producing molten glass and method for producing glass article |
| abstract | The invention provides a method for producing molten glass, which can reduce the melting delay of glass raw materials. The method for producing molten glass is characterized by melting a glass raw material composition containing silica sand, alumina and an alkali metal source to produce a glass having SiO 2 Is 50 mol% or more of Al 2 O 3 5 mol% or more and Li 2 O、Na 2 O、K 2 The molten glass has a glass composition in which the total O content is 5 mol% or more, the silica sand has a D90 value of 450 [ mu ] m or more and a difference between D90 and D10 of 350 [ mu ] m or more, the alumina has a D90 value of 200 [ mu ] m or less, and the ratio of the volume of 0.1 to 5 [ mu ] m in the pore volume distribution of 0.004 to 5 [ mu ] m in pore diameter measured by mercury intrusion method is 60% or more. |
