강화된 유리 물품을 형성하는 방법이 제공된다. 방법은 강화된 유리 물품을 제공하는 단계를 포함한다. 강화된 유리 물품은 내부 체적을 둘러싸는 외부 표면 및 내부 표면을 가진 측벽을 포함하는 용기 형태이다. 측벽은 외부 표면을 포함하는 외부 강화된 표면층, 내부 표면을 포함하는 내부 강화된 표면층, 및 인장 응력하에 있는, 외부 강화된 표면층과 내부 강화된 표면층 사이의, 중간층을 갖는다. 레이저-유도된 의도된 분리선은 유리 물품을 분리하지 않고 레이저를 통해 측벽을 조사함으로써 외부 강화된 표면층과 내부 강화된 표면층 사이의 미리 정해진 깊이로 중심층에 형성된다. A method of forming a strengthened glass article is provided. The method includes providing a strengthened glass article. The strengthened glass article is in the form of a container including a sidewall having an exterior surface and an interior surface that encloses an interior volume. The sidewall has an exterior strengthened surface layer that includes the exterior surface, an interior strengthened surface layer that includes the interior surface and a central layer between the exterior strengthened surface layer and the interior strengthened surface layer that is under a tensile stress. A laser-induced intended line of separation is formed in the central layer at a predetermined depth between the exterior strengthened surface layer and the interior strengthened surface layer by irradiating the sidewall with a laser without separating the glass article.
