Apparatus, systems and methods for increasing the strength of glass are disclosed. The strengthening of one portion of the glass article can be performed to a greater degree than another portion. Additionally, to mitigate against any distortion, such as warpage, physical manipulation of the glass article can be performed prior to or during strengthening, namely chemical strengthening. For example, in accordance with one embodiment, an outer surface of a glass article (e.g., cover glass) can be chemically strengthened to a greater degree than an inner surface of the glass article, yet the asymmetric strengthening does not induce distortion of the glass article because the glass article was physically manipulated, such as being bent, to counter any such distortion. Accordingly, glass articles that have undergone chemical strengthening processing are able to be not only thin and undistorted but also sufficiently strong and resistant to damage. The strengthened glass articles are well suited for use in consumer products, such as consumer electronic devices (e.g., portable electronic devices).
