Abstract
Locally cerammed optically transparent glass-ceramic articles for consumer products. The locally cerammed glass-ceramic articles may have one or more primary glass-ceramic regions including primary crystal phases of a glass-ceramic material and one or more secondary glass-ceramic regions including secondary crystal phases of the glass-ceramic material. The primary glass-ceramic region(s) may be optically transparent and the secondary glass-ceramic region(s) may be non-optically transparent. The primary glass-ceramic region(s) may have a fracture toughness less than the fracture toughness of the secondary glass-ceramic region(s).
