Methods of fabricating formed glass articles are described herein. In one embodiment, a method for fabricating a formed glass article may include forming a glass ribbon, forming a parison, and shaping the parison to form a glass article. The glass article may be attached to the glass ribbon at an attachment region defining an edge of the glass article. The process may also include contacting the attachment region with a focal line of a laser beam and separating the glass article from the glass ribbon at the attachment region. The attachment region may be perforated by the laser beam and the focal line may be substantially perpendicular to the plane of the glass ribbon.
