Evaluation and comparison of methods for forensic glass source conclusions.

Float glass, a common type of glass used in windows and doors, can be important evidence in the investigation of a crime. If fragments are optically indistinguishable, they may be distinguishable in their chemical compositions, which can be measured using inductively coupled mass spectrometry with a laser add-on (LA-ICP-MS) [14]. If the measurements are "similar enough" then the recovered fragment is indistinguishable from the crime scene glass [1].
