1. A method of forming an anti-counterfeit marking in a pharmaceutical package, comprising:
focusing a pulsed laser beam at a point on a surface of a glass body formed from an alkali-aluminosilicate glass composition; and
translating the pulsed laser beam along a scan path along the surface effective to remove a polymer-based coating from the surface of the glass body without affecting the surface of the glass body, thereby forming the anticounterfeit marking on the glass article, the anticounterfeit marking comprising at least a portion of the polymer-based coating that has been removed from the surface of the glass body to expose the surface of the glass body.
