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). L'invention concerne des articles vitrocéramiques optiquement transparents, localement céramisés, destinés à des produits de consommation. Les articles vitrocéramiques localement céramisés peuvent présenter une ou plusieurs régions vitrocéramiques primaires, comprenant des phases cristallines primaires d'un matériau vitrocéramique, et une ou plusieurs régions vitrocéramiques secondaires, comprenant des phases cristallines secondaires du matériau vitrocéramique. Lesdites régions vitrocéramiques primaires peuvent être optiquement transparentes et lesdites régions vitrocéramiques secondaires peuvent être non optiquement transparentes. Lesdites régions vitrocéramiques primaires peuvent présenter une ténacité à la rupture inférieure à la ténacité à la rupture desdites régions vitrocéramiques secondaires.
