A method of providing locally annealed regions for a glass article. The method includes providing a strengthened glass article having a first surface compressive stress and a first depth of layer of compressive stress, annealing the strengthened glass article to achieve a second surface compressive stress and a second depth of layer of compressive stress, and masking a portion of the glass article during the annealing step to achieve a third surface compressive stress and a third depth of layer of compressive stress in the masked portion. The glass article can be a laminate structure comprising a first glass layer, a second glass layer, and at least one polymer interlayer intermediate the first and second glass layers. The glass layers can include differing surface compressive stresses depths of layer of compressive stress. |
