How is the analysis of glass used in CSI?

Richard Saferstein (Former Chief Forensic Scientist) gives expert video advice on: How is the analysis of glass used in CSI?; What are the different kinds of glass studied in CSI?; How can comparison of glass fragments help in CSI? and more...

Glass analysis usually comes about when glass is broken, typically during a breaking and entering when fragments of glass will be scattered and perhaps will be caught in the clothing of the perpetrator, and when those fragments are brought back to the crime lab they will be linked, hopefully, by the crime lab technician to the broken glass at the crime scene. This link is normally established by looking at various physical properties of glass such as density and refractive index.
