Abstract
A glass includes a first glass portion and a second glass portion. The first glass portion has a higher ion packing density than the second glass portion (has a composition that forms a glass in which, out of plastic deformation characteristics, plastic flow is dominant). The second glass has a lower ion packing density than the first glass portion (has a composition that forms a glass in which, out of the plastic deformation characteristics, densification is dominant).
