Question- What is Forensic Glass Examination?
Answer- 👉Forensic examination of glass consists of the examination of two or more fragments to determine whether they have a common origin.
👉Identifying broken glass fragments having a common source to the exclusion of all other sources may only be done if they can be physically matched together.
Question- How will you analyse Glass fragments in lab?
Answer- 👉Submitted samples from a crime scene must first be confirmed as glass. ✔Differentiating glass from plastic is done by examining hardness, solubility, and observation with a polarized light microscope. ✔Once confirmed as glass, the examiner will perform an analysis of
📌physical properties, such as; color, fluorescence, thickness, curvature, density, 📌optical properties, such as; Refractive Index 📌and chemical composition.
✔ no further comparison is needed if any difference between questioned and known samples is found during analysis.
