Abstract
Apparatus, systems and methods for increasing the strength of glass are disclosed. The use of multi-bath chemical processing for a glass article can facilitate controlled chemical strengthening. Through multi-bath (or multi-step) chemical processing, differing levels of strengthening can be achieved for different portion of glass articles. The multi-bath chemical processing can be achieved through the use of successive chemical baths. Accordingly, glass articles that have undergone multi-bath chemical processing are able to be not only thin 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). In one embodiment, the glass member can pertain to a glass cover for a housing of an electronic device.
