The evidential value of small glass particles has been recognised for quite some time. While physical properties such as RI & density offer some discrimination of samples, they offer little in the way of classification of glass product type. Further, with improved glass manufacturing process, the range of physical properties seen in modern glass samples is decreasing. Many have advocated the use of elemental analysis for the purpose of forensic glass analysis. Various instrumental techniques have been employed, including flameless atomic absorption spectrometry, inductively coupled plasma atomic emission spectrometry, & energy dispersive X-ray fluorescence spectrometry. These more commonly employed methods are discussed with regard to the application to forensic glass analysis. Advantages & disadvantages of each technique are highlighted.
