  • METHOD FOR MANUFACTURING TEMPERED GLASS SHEET
    Publication number: 20160083292
    Abstract: A method of manufacturing a tempered glass sheet includes: an arrangement step of arranging a plurality of glass sheets to be tempered, each having a substantially rectangular shape and a sheet thickness of 1.0 mm or less, in a support in an upright posture in a thickness direction at an interval of 10 mm or less, to thereby obtain an arrangement of glass sheets to be tempered; a tempering step of immersing the arrangement of glass sheets to be tempered in an ion exchange solution so as to subject the arrangement of glass sheets to be tempered to ion exchange treatment, to thereby obtain an arrangement of tempered glass sheets; an annealing step of annealing the arrangement of tempered glass sheets; and a removal step of removing each of tempered glass sheets forming the arrangement of tempered glass sheets from the support.
