Japanese Patent JP7439645
Kind Code:
B2
Abstract:
To provide a manufacturing method capable of properly managing stress characteristics of chemically strengthened glass.SOLUTION: A manufacturing method of chemically strengthened glass includes: (1) immersing, into a single molten salt composition, and at the same time chemically strengthening, first glass and second glass being glass having at least one of K-Na replacement speed and Na-Li replacement speed faster than that of the first glass in ion-exchange so as to obtain first chemically strengthened glass being the first glass chemically strengthened and second chemically strengthened glass being the second glass chemically strengthened; (2) measuring stress characteristics of the second chemically strengthened glass; and (3) checking whether the stress characteristics of the second chemically strengthened glass is within a designed range.SELECTED DRAWING: Figure 1
