    Abstract: A scratch resistant alkali aluminoborosilicate glass. The glass is chemically strengthened and has a surface layer that is rich in silica with respect to the remainder of the glass article. The chemically strengthened glass is then treated with an aqueous solution of a mineral acid other than hydrofluoric acid, such as, for example, HCl, HNO3, H2SO4, or the like, to selective leach elements from the glass and leave behind a silica-rich surface layer. The silica-rich surface layer improves the Knoop scratch threshold of the ion exchanged glass compared to ion exchanged glass that are not treated with the acid solution as well as the post-scratch retained strength of the glass.
