    Abstract: A glass article includes lithium aluminosilicate, includes a first surface, a second surface opposed to the first surface, a first compressive region extending from the first surface to a first compression depth, a second compressive region extending from the second surface to a second compression depth, and, a tensile region disposed between the first compression depth and the second compression depth, where a stress profile of the first compressive region has a first local minimum point at which the stress profile is convex downward and a first local maximum point at which the stress profile is convex upward, where a depth of the first local maximum point is greater than a depth of the first local minimum point, and where a stress of the first local maximum point is greater than a compressive stress of the first local minimum point.

    Abstract: A glass strength evaluation apparatus includes a support unit, a plate disposed on the support unit and including a surface on which a glass article, which is a target to be tested, is disposed, a fixing jig disposed on the plate and a power unit lifting up or down the fixing jig in a vertical direction toward the surface of the plate. The fixing jig includes a body portion, which extends in the vertical direction and lower fixing bolts. A press-fitting member insertion opening is recessed from a bottom of the body portion to extend in an upward direction, lower fixing bolt insertion holes penetrate the body portion, from one side of the body portion, in a first horizontal direction intersecting the vertical direction, to be extended to the press-fitting insertion opening, and lower fixing bolts are coupled into the lower fixing bolt insertion holes.

    Abstract: A glass product includes: a first compressive region at a first surface; a second compressive region at a second surface; and a tensile region between the first and second compression regions. A stress profile of the first compressive region includes a first trend line between the first surface and a first transition point, a second trend line between the first transition point and a second transition point, and a third trend line between the second transition point and a point at a first compression depth from the first surface. A depth from the first surface to the first transition point is 10 μm or less, a stress at the first transition point is 200 MPa or greater, a depth from the first surface to the second transition point is 50 μm to 80 μm, and a stress at the second transition point is 40 MPa to 100 MPa.
