To provide a method for producing molten glass, whereby formation of dust can be suppressed when the molten glass is produced by an in-flight melting method. Granules containing silica sand and satisfying the following conditions (1) to (3) are used. (1) In a particle size distribution curve obtained by measuring the granules passed through a sieve having 1 mm openings by a dry laser diffraction scattering method, D50 representing the cumulative volume median diameter is from 80 to 800 μm. (2) The average particle size of the silica sand in the granules is from 1 to 40 μm. (3) In a particle size distribution curve obtained by measuring water-insoluble particles to constitute the granules by a wet laser diffraction scattering method, the ratio of D90/D10 is at least 10.

摘要:
To provide a process for producing glass raw material granules which are less likely to be formed into fine powders which cause a change of the glass composition at a time of forming a glass melt or defects of glass, and which can be preferably used for producing glass.A process for producing glass raw material granules, which comprises a granulation step of adding boric acid to either one of or both of a glass raw material powder and an alkaline solution having a pH of at least 9 and mixing the glass raw material powder together with the alkaline solution. The glass raw material powder preferably contains at least 10 mass % of boric acid.
